Deep Groove Ball Bearings

Considered as one of the most widely used bearing type due to its versatility and design which permits precision tolerance, even at high-speed. Deep groove ball bears utilize an uninterrupted raceway that makes it optimal for radial loads.

Deep groove ball bearing

We stock a range of deep groove ball bearings from FAG and PFI Bearings that are available in radial and axial designs for many different variants.

Single Row Deep Groove Ball Bearings

Single row deep groove ball bearings are available in open and sealed designs. They are designed for high to very high speeds and can accommodate radial as well as axial forces. The single-row bearings are particularly suitable where:

  • High and very high speeds are required
  • The bearing arrangement must be operated with very low friction
  • Very low running noise is required, without reducing the speed, load carrying capacity and operating life of the bearing
  • High demands are made on the sealing of the bearing, without increasing heat generation or limiting the speed
  • The bearing position is to be designed particularly economically

Double Row Deep Groove Ball Bearings

Double row deep groove ball bearings correspond with single-row deep groove ball bearings in design and are used when the radial load capacity of single-row deep groove ball bearings is insufficient. Double-row bearings can be considered for bearing arrangements when:

  • The load carrying capacity of single row deep groove ball bearings is no longer sufficient 
  • Axial loads in both directions and/or tilting moments must be supported in addition to radial loads 
  • A high load carrying capacity is required and the design envelope available in a radial and axial direction is relatively small

Axial Deep Groove Ball Bearings

The axial deep groove ball bearings are available in single or double-direction design variants. These bearings are especially well suited to high axial loads.

  • Standardised, ready-to-fit units with high axial load carrying capacity
  • Suitable exclusively for the support of predominantly axial loads 
  • Particularly suitable where the bearing position is subjected to high axial loads from one or both sides, but the requirements for axial load carrying capacity are not so high that axial cylindrical roller bearings with even higher load carrying capacity must be used
  • Permit higher speeds than roller or needle roller and cage assemblies 
  • Compensate, in conjunction with a spherical housing locating washer, static misalignments between the shaft and housing

Variants of deep groove ball bearings:

  • Deep groove ball bearings
  • Axial deep groove ball bearings
  • Generation C deep groove ball bearings
