Double Direction thrust ball bearings of the series 523

The special feature of this series. Main dimensions according to DIN 711. Double direction thrust deep groove ball bearings of the series 523 are suitable for very high axial loads in both directions. They withstand higher loads than thrust deep groove ball bearings of the series 522 with the same inner diameter and are dismountable.

  • double direction design
  • consists of shaft washers, flat housing locating washers, and ball-cage assemblies
  • suitable for high axial loads in both directions
  • can be dismantled, the bearing washers and the ball cage assemblies can be mounted separately
  • manufacturers of bearings, such as FAG, KOYO, NSK, SKF, NTN-SNR, etc. assign different suffixes for their characteristics; for better orientation, take note of the comparison table of bearings (see further information)

The special feature of this series

Thrust ball bearings are pure thrust bearings, which means they can only withstand major axial loads. However, tiny radial forces can also be transmitted depending on the axial load and speed range.

Thrust ball bearings also include thrust deep groove ball bearings and thrust angular contact ball bearings. Thrust angular contact ball bearings can withstand lower axial load than similar thrust ball bearings but have a higher radial load capacity.

  • Separable and interchangeable

The separable parts of TFL thrust ball bearings are interchangeable. This facilitates installation and removal, as well as maintenance and inspection.

  • Initial misalignment

Bearings with spherical races can accommodate initial misalignment.

  • Interference fit

The shaft ring has a round hole for an interference fit. The hole of the bearing seat washer is turned and is always larger than the hole of the shaft washer.

Available brands: INA/FAG, KOYO, NSK, SKF, NTN-SNR, IKO, NACHI, TIMKEN, different suffixes are assigned according to their characteristics. Please pay attention to the bearing comparison table (see more information). In addition, to meet the special needs of the equipment, we accept bearing customization to meet your specific needs.

Application of 523 Series Double Direction thrust ball bearings

A thrust bearing is a rotating bearing that rotates between parts to reduce friction and is designed to support axial loads (mainly used in low-speed applications). It is the axial bearing that allows rotation between the parts.
