Bosch Rexroth R165922165 ball runner block. A runner block is the moving carriage of a profiled rail linear guide: recirculating ball tracks inside the block roll on the ground raceways of a hardened steel guide rail, carrying load in every direction perpendicular to travel while leaving the travel direction nearly free. Manufacturer: Rexroth. Part Number: R165922165. Product Family: Rexroth Ball Rail System. Rolling Elements: recirculating steel balls.
R165922165 — Bosch Rexroth nine-digit material number, the ordering identity for this runner block.
R-165-922-165 — the same material number in the punctuated form printed on packaging and used in parts lists.
R165 — Rexroth’s ball runner block number range within the Ball Rail System programme.
A recirculating ball carriage takes radial, reverse-radial and both lateral loads on a single block, so one rail-and-block pair constrains an axis in five degrees of freedom and leaves only the travel direction free. That is what allows a gantry or slide to be built from one rail rather than two crossed ways. Rolling contact keeps the friction coefficient low and close to constant across the speed range, which is what lets a servo axis settle on position and repeat it across long duty cycles rather than fighting stick-slip.
The block bolts to the moving carriage through threaded mounting holes in its top face and rides on a matching Rexroth ball guide rail. Runner blocks and rails are a matched system within the Ball Rail programme: the block seats on the rail profile of its own size.
Unit Quantity: 1 Pc. One runner block per listing.
Rexroth linear motion components are ordered and cross-referenced by material number. R165922165, R165 922 165 and R-165-922-165 are the same part; a machine parts list, assembly drawing or maintenance BOM quoting any of those strings resolves to this runner block.
