A roller screw is a mechanical actuator similar to a ball screw that uses rollers as the load transfer elements between nut and screw instead of balls. The rollers are typically threaded but may also be grooved depending on roller screw type. Providing more bearing points than ball screws within a given volume, roller screws can be more compact for a given load capacity while providing similar ...

Compared with other thrust roller bearings, this type of bearing has a lower friction coefficient, higher speed, and self-aligning ability. 29000 type rollers are asymmetric spherical rollers, which can reduce the relative sliding of rollers and raceways during work, and the rollers are long and large in diameter.

Browse All Bearings While roller bearings can handle higher loads than conventional ball bearings, their applications are generally limited to low-speed operations. Many types of roller bearings are self-aligning, and are easily able to overcome misalignment and mounting issues — cutting down on maintenance, repair, and labor needs.

Ball-type axle bearing assemblies are pressed on and off the axle shaft, and a retainer ring made of soft metal is pressed onto the shaft against the wheel bearing. Roller axle bearings are lubricated by gear oil inside the differential housing, and are most often pressed into that housing rather than onto the axle.

Ball bushings are versatile as they can be used fully supported (open type) or end supported (closed type). Linear ball and roller guides must be fully supported from either above or below. Whilst the roller linear guides offer higher load capacities, recent product development of the ball guides has narrowed the gap between their load capacities.

The ball deflects vertically 20 um per 12 kN, laterally 27 um per kN. The roller deflects vertically 12 um per 12 kN, laterally 17 um per kN. I don't claim this one case to represent all cases (i.e. all manufacturers), but the rollers are not quite twice as stiff in this case. In size 35, otherwise the same.
