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.

For the purposes of this document, the terms and definitions given in ISO 1132-1, ISO 5593,ISO 24393 andthe following apply.
3.1
linear rail guideprofiled rail guide
(monorail guidance system) linear motion rolling bearing unit consisting of a profiled rail or profiled guidewayand one or more ball carriages or roller carriages
NOTE Adapted from lSO 24393:2008, definition 02.02.01.
3.2
ball carriage profiled rail guide
linear rail guide consisting of one or more ball carriages and a profiled rail or profiled guideway
[ISO 24393:2008, definition 02.02.03]
NOTE The amount of linear movement (stroke length) is unlimited as the ball carriage has a ball recirculating feature.

linear rail guide consisting of one or more roller carriages and a profiled rail or profiled guideway
[ISO 24393:2008, definition 02.02.04]
NOTE The amount of linear movement (stroke length) is unlimited as the roller carriage has a roller recirculating feature.
3.4
ball carriage
