SX crossed roller bearings are bearings for precision applications and conform in their dimensions to ISO dimension series 18 in accordance with DIN 616. They consist of outer rings, inner rings, rolling elements and plastic spacers. The outer ring is split and held together by three retaining rings.
Rollers in an X arrangement
Due to the X arrangement of the cylindrical rollers, these bearings can support axial loads from both directions as well as radial loads, tilting moment loads and combined loads using a single bearing position. This makes it possible to reduce designs with two bearing positions to just one. Crossed roller bearings are very rigid, offer high running accuracy and are available with normal clearance, reduced clearance or preload.
Crossed roller bearings are also available with corrosion protection featuring the INA special coating Corrotect®.
Sealing / Lubrication
The bearings are not sealed. If sealing of the bearing position is required, this can be freely designed within the adjacent construction. Crossed roller bearings are preserved with oil. The bearings must be lubricated before initial operation.
