Heavy-duty truck recirculating-ball steering system – split-type, fully assembled four-point contact ball bearing

Features: Designed for use on both sides of the screw–nut pair in a transmission assembly, this solution accommodates the substantial bidirectional axial loads generated by the reciprocating screw motion. It employs a four-point contact ball bearing configuration, with either a full‑complement design or a cage‑type separator serving as the retainer. By replacing conventional tapered roller bearing arrangements or thrust angular contact ball bearing setups, it reduces system torque and minimizes bearing slippage. It is also suitable for applications such as large rotary tables and construction machinery.

Product Description

Heavy-duty truck recirculating-ball steering system – split-type, fully assembled four-point contact ball bearings

Features: Applied to both sides of the screw–nut pair in the drive assembly, this configuration accommodates the substantial bidirectional axial loads generated by the reciprocating screw motion. To address these demands, a four-point contact ball bearing design is employed, with either a full‑complement or a cage‑type separator serving as the retainer. This approach replaces conventional tapered roller bearing arrangements or thrust angular contact ball bearing setups, thereby reducing system torque and minimizing bearing slippage.

It can also be applied in fields such as large turntables and construction machinery.

Single-row deep groove ball bearing

It is the most typical structural form among rolling bearings and finds wide application. In addition to supporting radial loads, it can also accommodate axial loads in both directions. With a low friction torque, it is ideally suited for applications requiring high-speed rotation, low noise, and minimal vibration.

Angular contact ball bearing

They are primarily used in high-speed rotating applications with relatively light loads and can withstand combined radial and axial loads. When installed in pairs, angular contact ball bearings can handle combined radial and axial loads, with the radial component being dominant, and they can also accommodate purely radial loads. In a tandem arrangement, they can only support axial loads in one direction, whereas the other two arrangements can accommodate axial loads in either direction.

Cylindrical roller bearing

Cylindrical roller bearings are line-contact bearings. They offer high load-carrying capacity and primarily support radial loads. The rolling elements experience low friction against the raceway shoulders, making them well suited for high-speed operation. Depending on whether the rings are equipped with shoulders, they can be classified into single-row cylindrical roller bearings—such as NU, NJ, NUP, N, and NF—and double-row cylindrical roller bearings—such as NNU and NN.
