SBR Rail Bearing Blocks — Sizes & Specifications
The SBR series is an open-type bearing block made to run on SBR supported rails, where the shaft is carried by an aluminum rail along its full length. Fully supported shafts do not sag, so SBR blocks are the standard choice for long-travel gantries, CNC routers and woodworking machinery. BPK supplies SBR10UU to SBR50UU, factory-direct from Yandian, Shandong, for importers, distributors and OEM buyers.
