BALL BEARINGS OBLIQUE CONTACT TECHNICAL FEATURES
INNER AND OUTER RING
Material: Core hardened steel 100Cr6 (UNI 3097 – WNr. 1.3505 ) or 100 CrMo7 (WNr. 1.3507) according to dimensions. On request they can be manufactured in hardening steel for specific applications.
Heat treatment: Annealing (annealing of workability), hardening & tempering These treatments will be always performed ensuring a stabilization SZ0 ( for use of bearings without dilatation of rings at temperatures 150°).
On request these treatments can be performed ensuring a final stabilization SZ1 & SZ2 :
SZ1 – for functioning without dilatation of rings until 200° ( suffix SZ1)
SZ2 – for functioning without dilatation of rings until 250° ( suffix SZ2).
Hardness: 58/62 HRc
Single row angular contact ball bearings are normally provided with one of the following types of cages, according to the range and dimensions:
Bearings provided with polyamide cage 6,6 reinforced with glass fibres, can be used at work temperatures until 120°. In the applications where the temperature is constantly over 120°or under -40° C, it is necessary to use bearings with metallic cage. If there is a cooling system that uses constantly ammonia we recommend bearings with steel massive cage.
