Ball Screw End Bearings

These plastic parts are responsible for scooping ball bearings off the ball screw raceway winding picking them up off the track and recirculating the ball bearings to the other end of the ball nut and dropping them back on the track.

Ball screw end bearings. We offer flanged and non flanged series for both standard and rotating nut mountings. Rexroth precision pillow block units enable. The bf simple floating support has only a standard ball bearing that provides rotational support on the end of the ball screw opposite of where the drive occurs typically a motor or pulley. Rexroth precision ball screw assemblies product overview rexroth precision ball screw assemblies with driven screws end bearings rexroth precision ball screw assemblies are available with steel or aluminium pillow block bearings or bearing units complete with matching slotted nuts.

Please consult rockford ball screw s engineering tech team for application assistance if required. To meet these requirements screw drives can be supported at both ends by skf super precision angular contact thrust ball bearings. Housed cartridge and pillow block units facilitate bolting to machine tool surfaces. Internal ball bearings provide smooth low friction travel in applications that require high speeds accurate positioning and repeatable movement.

The ball screw drive is an assembly that converts rotary motion to linear motion or vice versa. These bearing mounts are designed to support radial and axial load components of force. The bm series bearing mounts are simple supports that utilize a set of angular contact ball bearings mounted back to back. This video serves as an introduction to the design and basic functions of ball screw support bearings.

It consists of a ball screw and a ball nut packaged as an assembly with recirculating ball bearings. The interface between the ball screw and the nut is made by ball bearings which roll in matching ball forms. Our broad line of timken fafnir ball screw support bearings includes single and double row designs with a variety of mounting configurations. Because these critical parts are made from plastic they can wear quickly and crack blocking the return of.
