Friction-reduced rolling bearings increase efficiency and sustainability
Rolling bearings feature especially low friction characteristics, making it possible to reduce bearing friction by half, and offering the construction machinery sector the opportunity to achieve significant carbon dioxide savings without imposing high development costs. Stefan Scharting Schaeffler KG Schweinfurt, Germany Rolling bearings with optimized friction and performance characteristics can have a significant influence when it comes to reducing the power […]
Full ceramic radial bearings for extreme environment applications
The XTREME 6000 ZrO2 Series of full ceramic radial bearings from CeramicSpeed are designed to provide levels of performance in extreme environments beyond the capabilities of steel and even hybrid bearings. The complementing components of these bearings were carefully selected to provide the highest levels of performance in high temperatures, and adverse environments such as; […]
Smart fixed flange bearings unlock predictive maintenance
igus has developed intelligent two- and four-hole fixed flange bearings with wireless sensing capabilities for wear detection, enabling condition monitoring and preventing costly machine breakdowns. Constructed from self-lubricating, high-performance plastic, the bearings feature an integrated abrasion sensor, thin circuit board and cableless battery supply. Wear interrupts the board’s conductor paths, causing the electronics to lose […]
How to calculate crossed roller bearing life (with various load types)
A crossed roller bearing is a type of rotary bearing that uses cylindrical rollers arranged in a crisscross pattern, with each roller oriented at a 90 degree angle relative to the one adjacent to it. This arrangement allows crossed roller bearings to withstand radial, axial, and moment loads, so they can often replace dual-bearing arrangements, for […]
Why is viscosity important for bearing lubrication?
Lubrication — or, more correctly, improper or insufficient lubrication — is one of the leading causes of equipment failures in industrial applications. Without it, sliding, rolling, or meshing surfaces experience significant friction, heat, and wear, leading to increased noise, loss of accuracy, and reduced equipment life. One of the most important characteristics of a lubricant […]
How to specify motion components for cleanroom environments: Part 2
In this two-part article, we cover the products, materials, and features that designers and engineers should specify when choosing motion components for cleanroom environments. In part 1, we looked at how to reduce particle generation due to friction between moving components. In this second part, we’ll look at another source of contamination — outgassing — […]
How to specify motion components for cleanroom environments: Part 1
In this two-part article, we cover the products, materials, and features that designers and engineers should specify when choosing motion components for cleanroom environments. In part 1, we look at how to reduce particle generation due to friction between moving components. Designers of automation systems are tasked with many competing demands, such as balancing cost and performance, […]
New igus robolink Apiro is modular kinematics system for automation
igus now sells components as part of a modular motion system called robolink Apiro. The systems could soon make designing and using individual automation setups more cost effective and much easier. With robolink Apiro, design engineers can choose from three lubrication-free worm gears for standard, inverted and linear movement. For users, the device offers setups […]
Rotary bearings: Summary of types and variations
Rotary bearings are common components in motion systems. They’re used in gearboxes, motors, pulleys, fans, pumps—virtually any time a shaft is rotating, rotary bearings are there to reduce friction and support radial or axial loads. The classification of rotary bearings begins with the type of bearing that supports the load—ball or roller. Within the ball […]
