CUSCINETTO SKF 3308 ATN9 – Cuscinetti obliqui a sfere

Description

Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space. They can operate at high speeds and are more suitable than deep groove ball bearings for supporting large axial forces in both directions.

  • High-speed capability
  • Accommodate relatively high radial loads, high axial loads in both directions and tilting moments
  • Suitable where a stiff bearing arrangement is required
  • Require less axial space than equivalent pair of single row angular contact ball bearings
