Troubleshooting V-belt wear and failure
Although there are more than a dozen symptoms of premature wear and impending failure for V-belts — ranging from visible damage to audible noise — there are a few key ways that these friction-based … [Read More...] about Troubleshooting V-belt wear and failure
Linear rails from Rollon simplify design of high-performance automated systems
Rollon has upgraded its Telerace family of linear rails to help designers simplify projects and enhance the efficiency of automated systems. Two Telerace families of cold-drawn steel rails now feature … [Read More...] about Linear rails from Rollon simplify design of high-performance automated systems
When are stepper motors paired with ball screws (rather than lead screws)?
Stepper motors are widely used in industrial and consumer applications ranging from packaging equipment and medical devices to 3D printers and vending machines. They have excellent torque production … [Read More...] about When are stepper motors paired with ball screws (rather than lead screws)?
What do the belt section designations H, J, K, L, and M mean for ribbed V-belts?
V-belts rely on friction caused by the "wedging" of the belt between pulley flanges — together with internal fiber cords — to transmit power in a wide range of industrial and consumer-goods … [Read More...] about What do the belt section designations H, J, K, L, and M mean for ribbed V-belts?

Rack and pinion drives: A new look at an old technology
Comparing rack and pinion drives with other linear drives such as belts and ball screws shows that sometimes simplicity can be the ultimate sophistication. YYC North … [Read More...] about Rack and pinion drives: A new look at an old technology
What are the benefits of six-row linear bearings
The most common types of recirculating linear bearings use four rows of balls — two on each side of the bearing block — to provide good load capacity and rigidity. But the four-row design means that … [Read More...] about What are the benefits of six-row linear bearings
Contact angle: What is it and how does it affect linear bearing performance?
In profiled rail linear guides that use balls or rollers, the geometry and arrangement of the bearing raceways play a significant role in the bearing's load capacity, friction, rigidity, and ability … [Read More...] about Contact angle: What is it and how does it affect linear bearing performance?
How to choose a lubricant for recirculating linear bearings
All metal-on-metal recirculating bearings require lubrication in order to function properly and provide a reasonable bearing life. Lubrication reduces friction and heat by separating the rolling … [Read More...] about How to choose a lubricant for recirculating linear bearings
