Product Introduction

FAG Angular contact ball bearing The internal steel ball and the raceway form a fixed contact angle, which can bear radial load and unidirectional axial composite load at the same time. When single-row bearings are operated under radial loads, axial component forces will be generated. Generally, they need to be installed in pairs in back-to-back DB, face-to-face DF or series DT. Preload can also be applied to improve the rotational rigidity and positioning accuracy of the shaft system.

The product line is divided into five major sections: industrial general-purpose single row angular contact ball bearings, universal matched bearings, double row angular contact ball bearings, four-point contact ball bearings, and B‑HSS‑HCB ultra-precision machine tool spindle bearings. The high-performance upgraded version of X‑life optimizes the contact profile between the raceway and the steel ball, reduces edge stress, significantly increases the rated load and fatigue life, has a higher limit speed and lower vibration and noise.

Bearings are available in a variety of contact angle specifications: C (15°) is suitable for ultra-high speed working conditions; E (25°) is the main force in industrial general use; B (40°) has the strongest axial load capacity. The cage can be optionally made of glass fiber reinforced nylon TVH cage, which has low temperature rise during high-speed operation; the heavy-duty large model uses a solid brass cage; the high-precision spindle model uses a phenolic resin T cage, guided by the outer ring, and is suitable for oil and gas lubrication ultra-high-speed conditions. The universal pairing model has been precisely selected at the factory and can be directly assembled in pairs without additional processing of spacers. Sealing style-2RS is equipped with rubber sealing rings on both sides and is pre-filled with long-lasting grease at the factory to achieve maintenance-free operation.

The accuracy level of high-precision spindle bearings covers P5, P4, and P4S ultra-high-precision specifications; HCB hybrid ceramic ball insulated spindle bearings, ceramic rolling elements can block shaft current, effectively avoiding electric corrosion damage to the variable frequency motor spindle.
