Self-aligning ball bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, inner rings with a cylindrical or tapered bore and ball and cage assemblies. The bearings are available in open and sealed versions.
Thin section bearings have high precision, are very quiet and have high load carrying capacity. These ball bearings are available in three different designs and have an extremely small, predominantly square cross-section. Within each series, the cross-section remains constant even for larger shaft diameters and housing bores. The bearings are therefore also described as Constant Section (CS). This special feature distinguishes thin section bearings from conventional bearings as standardised in ISO series.
Four point contact bearings are single row angular contact ball bearings and therefore require significantly less space in an axial direction than double row designs.
Spindle bearings are single row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in open and sealed versions.
Single row angular contact ball bearings
Single row angular contact ball bearings are self-retaining units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages.
Double row angular contact ball bearings
Double row angular contact ball bearings are units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages. They correspond in design to single row angular contact ball bearings in pairs in an O arrangement but give a narrower design than these.
