Choosing the proper bearing lubricant can help keep a facility’s machinery safe and operational. Emerson Bearing Boston, a bearing company catering to Original Equipment Manufacturers (OEM) and Maintenance, Repair and Operations (MRO) markets, offers tips for proper bearing lubricant selection and a complimentary online “Bearing Maintenance Guide”.

Grease or lubricant selection can make a huge difference in the performance and life span of a piece of equipment or system. While the proper lubricant can ensure smooth and reliable performance, the wrong lubricant can result in frequent maintenance and service outages.

For industrial applications, bearing lubricants come in three basic forms: oils and fluid lubricants; semi-solid or solid grease products (which are similar to fluid lubricants but also include a thickening agent); and dry lubricant powders and films for precise placement.

Below, Emerson Bearing offers five grease/lubricant selection tips:

– The machinery system and its operating conditions dictate which form and makeup of lubricant are the most suitable for use. 

– Because lubricants need to be able to withstand heat and reduce friction, the most important factors to consider when selecting a lubricant are operating speeds, minimum and maximum system, and the viscosity of the lubricant in that range of operating temperatures.

– Different greases should not be combined unless the product directions explicitly allow for such mixtures. Instead, look for specialty greases and lubricants specifically designed for the conditions of the machinery and systems. 

– Mixing two or more greases, with different base oils together, may result in a final lubricant product that loses many of the individual products’ unique benefits.

– It’s critical to match the service life of the grease to the service life of the bearing.

From military and defense equipment to mining, manufacturing, transportation and even industrial bottling technologies, bearing selection plays a critical role when it comes to heavy load applications that require great freedom of movement.

Emerson Bearing, based in Boston, is expanding their line of Slewing Ring Bearings, an innovative bearing solution that offers a number of unique benefits over other ball and roller bearings.

Precision slewing ring bearings are a type of angular bearing that consist of two concentric rings with balls or rollers that enhance movement in load-bearing and power transmission applications. The two rings may be constructed with toothed gears to increase torque and can facilitate movement in any direction from the center of the bearing.

What Sets Slewing Ring Bearings Apart

Slewing ring bearings have the load carrying capacity as well as high material stiffness to ensure sufficient support in rigid bearing applications. They also provide 360-degree joint support for complex load bearing systems, which allows for concurrent movement on multiple axes. Slewing ring bearings have a shaftless design and are valuable for their low-friction and freedom of movement. All of these advantages result in an extended service life.

The versatility and efficiency of slewing ring bearings makes them ideal for use in a range of industries. Common applications include:

– Missile launchers, tank turrets and optical devices in the Military and Defense industry. Slewing ring bearings are often used in military and defense equipment that must direct heavy loads with a high degree of precision. 

– The construction industry, particularly in load-bearing and lifting applications such as lifts, cranes, hydraulic excavators and borers. 

– Industrial bottling applications including sanitization, washing capping, and labeling functions. The 360-degree rotation of slewing rings makes them especially useful.

– Mining excavation and tunnel boring, where equipment must be able to move freely under heavy loads.

– Transportation such as trains, trams, and subways. Slewing rings are often used to facilitate free and easy vehicle movement.

“Our bearing experts can assist in determining which bearing technologies would be most suitable by taking into consideration the specifications, recommendations, maintenance strategies, fatigue life and wear resistance of bearings in relation to the application,” explained Steve Katz, president of Emerson Bearing Boston.

Emerson Bearing Boston expands line of innovative bearing solution for heavy load applicationsRead More

Emerson Bearing Boston, a bearing company catering to Original Equipment Manufacturers (OEM) and Maintenance, Repair and Operations (MRO) markets around the world, has expanded their bearing line to include Shaft Grounding Devices, which reduce the risk of danger and protect motor bearings from damage.

Motor shaft voltages have the potential to damage the components around them. If a shaft’s voltage exceeds the insulation capabilities of nearby cables or parts, it can cause both long-term and acute damage to motor bearings. Some high voltages can even lead to arcing between the shaft and the bearing. When this occurs, the arcing rapidly elevates the temperature of the bearing. Metal can vaporize and become permanently damaged and pitted from this process. 

Shaft grounding devices are a cost-efficient solution to preventing the currents produced by shaft voltage. They are utilized in a number of industries, including Marine, Manufacturing, Industrial and HVAC.

Shaft voltage can occur for a number of reasons. Usually, it can be traced back to leakages or induction. Some external sources may even influence the likelihood of shaft voltage occurring. Rubber belts creating friction against drive pulleys and other nearby coupled machines are a few examples of these. AC and DC motors with variable frequency drives (VFD) often produce induced electrical currents on the motor shaft.

Emerson Bearing includes top brand Helwig Carbon shaft-mounted grounding devices, which are the most economical means of protecting bearings from electrical discharge. AC systems with VFD control and DC motors with pulse width modulation (PWM) drives benefit greatly from this added security. Grounding provides a low-impedance path for shaft voltage to travel through. Currents are forced away from bearings and voltage is prevented from building gradually over time on rotors. This simple technology is all it takes to dramatically reduce the risk of danger or property damage. 

Helwig Carbon shaft-mounted grounding devices offer exceptional bearing protection and prevent failure. With sizes available for both large and small motors and internal mounting capabilities, they’re ideal for a number of applications, including: HVAC units; Pump motors; Fans; Air-handling equipment; Compressors; Elevators; Data centers; Chillers; and Conveyors.

Shafts ranging from 6mm (.2500”) to 225mm (9.000”) are available. Sealed options also increase resistance in contaminated environments like wash-down applications. 

“Grounding devices are the most effective technology for minimizing shaft voltage and often outlast the units they’re installed on,” explained Steve Katz, president of Emerson Bearing Boston. “Grounding devices are the smartest choice an organization can make when it comes to protecting their people and their equipment from dangerous, damaging currents.”

Choosing a bearing catalog can be intimidating and confusing – as some seem to be written in a secret code, with a series of letters and numbers that are unknown to anyone who hasn’t chosen a bearing before. 

Emerson Bearing Boston, a bearing company catering to Original Equipment Manufacturers (OEM) and Maintenance, Repair and Operations (MRO) markets around the world, shares tips for cracking the code and understanding how to get the most from your bearings.

Rolling bearings are designated by codes that indicate the construction, dimensions, tolerances, and clearances of each bearing. Tolerance is the limit of random (unintentional) deviation of a dimension from its nominal value. Allowance is the amount of designed (intentional) deviation between two mating dimensions in a fit, which, in combination with their respective tolerances, results into a maximum and minimum clearance or interference.

Emerson Bearing breaks it all down:

The Codes in a bearing catalog can include any or all of these three parts: the basic code, prefixes, and suffixes. The basic code tells you what kind of bearing it is and its bore diameter (diameter of the inner ring). Prefixes indicate basic components in the bearing, and suffixes indicate any special characteristics or designs.

Basic Code consists of the bearing series, which indicates the type of bearing, and the bore number, which specifies the bore diameter. The bearing series can be made up of letters and/or numbers that designate the construction, diameter series, and in many cases the width series. The bore number indicates the bore diameter. If the bearing code only contains the basic code and doesn’t include any prefixes or suffixes, it means that it is a normal bearing with normal standards of form, precision, and clearance. 

Prefixes refer to basic bearing components and common prefixes include H for Tapered Roller Bearings-Inch, N for Cylindrical Roller Bearings-Metric, NN for Super Precision Cylindrical Roller Bearings, and S for Stainless Steel – to name just a few.

Suffixes indicate bearings with special characteristics or designs, including special outer forms, cages, precision tolerances, clearances, and other characteristics like heat treatment and noise behavior. The most common suffixes for internal design are E for Higher Capacity Bearings, UA for Close Axial Preload, UO for No Clearance, and UL for Light Preload. There are also suffixes for outer surface dimensions, sealings, cage materials, precision tolerances, bearing clearances and dimensionally stabilized bearings. Note that for bearings with both special precision tolerance and special clearance, the suffixes are combined.

“We are dedicated to helping our customers find the bearings they require,” explained Steve Katz, president. “Our team of experts can assist with proper bearing selection and equip customers with the knowledge needed – which often includes deciphering bearing codes – which  helps to ensure they avoid costly pitfalls and downtime.”
