About Ball and Roller Bearings

Easy-Install Mounted Cylindrical-Roller Bearings
A split housing means you can remove the top half of these bearings to inspect or repair shafts and components. This reduces downtime and minimizes the risk of damaging surrounding components.
Bearings for radial loads accommodate minor changes in your shaft’s length as it expands and contracts from your machinery heating up and cooling down. They are typically used in assemblies with long shafts and positioned away from the drive end.
Bearings for combined radial and thrust loads anchor the shaft in position and absorb the thrust load. However, they are not designed to handle your shaft expanding and contracting. They’re typically mounted near the drive side of an assembly.

Low-Friction Telescoping Slides
Use these slides for short-travel, high-speed applications where low-friction performance is a must. They have a bearing cage that eliminates ball collisions to extend service life.
Travel length is the total distance the carriage travels in both directions. For example, a slide with a 6" travel length travels 3" in each direction.
Note: Capacities listed are for horizontal mounting. If side mounted, load capacities are cut in half.
