Rolling bearings - Profiled rail guides for linear motion

rolling bearings - Part 2. Boundary dimensions and

tolerances for series 4 and 5

1 Scope

This Part of GB/T 32322 establishes the boundary dimensions and tolerances for

series 4 and 5 of linear motion rolling bearings, profiled rail guides.

These bearings consist of profiled rails with carriages, which can support forces from

all perpendicular directions and moments around all axes and consist of recirculating

rolling elements. The internal design of these 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 permitted by the manufacturer.
