BS ISO 12090-1 pdf download Rolling bearings — Profiled rail guides for linear motion rolling bearings Part 1: Boundary dimensions and tolerances for series 1, 2 and 3
1 Scope
This part of lSO 12090 establishes the boundary dimensions and tolerances for series 1, 2 and 3 of linearmotion rolling bearings,profiled rail guides.
These bearings consist of profiled rails with carriages, which can support forces from all perpendiculardirections and moments around all axes and consist of recirculating rolling elements. The internal design ofthese profiled rail guides is at the discretion of the manufacturer.
An assembly, as specified by the manufacturer,can comprise one or more carriages on a profiled rail.Therefore, the interchange or combination of these elements can only be carried out within the limits permittedby the manufacturer.
