Separable, they consist of inner ring and a cage with rollers Designed to carry large, and compound loads (axial and radial) in one direction only
313 series (with enlarged contact angle) are applied in order to carry largest axial loads
Cages are mainly made of steel (polyamide cages are very rare)
Bearings produced at present have modernised construction comparing to basic versions and characterise of higher load capacity and better rotary parameters. This was obtained by increasing number and size of rollers by keeping unchanged main dimensions of bearings. These constructions are marked with "A" after main symbol of bearing.
