DIN ISO 12090-2:2016-08

This standard specifies the boundary dimensions and tolerances for series 4 and 5 of profiled rail systems with recirculating rolling elements. These bearings consist of profiled rails and carriages with rolling element recirculation, which can support loads from all directions and can support moments around all axes. The internal structure, such as the design of the raceways, rolling elements and rolling element recirculation, is at the discretion of the manufacturer. An assembly as specified by the manufacturer may 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. The text of ISO 12090-2:2011 has been prepared by Technical Committee ISO/TC 4 "Rolling bearings" of the International Organization for Standardization (ISO). The responsible national committee is NA 118-01-11 AA "Linear-Wälzlager einschließlich Teile und Zubehör" ("Linear motion rolling bearings including parts and supplies ") at DIN Standards Committee Rolling Bearings and Plain Bearings (NAWGL).
