Features

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. Their construction is similar to a pair of single row angular contact ball bearings in an O arrangement but they are narrower to a certain extent. They differ in the size of the contact angle and the design of the bearing rings.
The bearings are available in open and sealed designs. Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for seals or shields. Sealed bearings are maintenance-free and therefore allow particularly economical bearing arrangements.
The angular adjustment facility of the angular contact ball bearings is very limited.

Sealing/lubrication

Series 38..-B, 30..-B, 32..-B and 33..-B with suffix 2RSR are sealed by lip seals on both sides. Contact seals are suitable for giving protection against dust, contamination and damp atmospheres.
Series with the suffix 2Z have gap seals on both sides.Sealed bearings are greased with a high quality grease and are lubricated for life. Bearings without seals can be lubricated with grease or oil.

Operating temperature

Open bearings are suitable for operating temperatures from –30 °C to +150 °C.

Caution

Bearings with cages made from glass fibre reinforced polyamide are suitable for operating temperatures up to +120 °C, restricted by the cage material.Bearings with suffix 2RSR are suitable for operating temperatures up to +110 °C, restricted by the lubricant and seal material.
