Deep Groove Ball Bearings
The versatile workhorse for motors, pumps and general machinery.
Overview
Simple, robust and low-friction. Carries radial and moderate axial loads in both directions at high speeds.
Deep groove ball bearings are the most widely used rolling bearing type. Deep, uninterrupted raceways closely conform to the balls, so the bearing can carry radial loads and axial loads in both directions while running quietly at high speeds.
We supply open, shielded and sealed versions from miniature to large bore sizes, with normal or increased internal clearance for applications with high operating temperatures or tight fits.
Key features
- Radial and moderate axial loads in both directions
- Low friction and noise for high-speed operation
- Open, shielded (ZZ / 2Z) and sealed (2RS) versions
- Normal, C3 and C4 internal clearance options
