Paired angular contact ball bearings: customized combinations for efficient load-bearing solutions

Paired angular contact ball bearings are bearing assemblies that combine two or more sets of unidirectional angular contact ball bearings in a specific way (back-to-back, face-to-face, series) and pre-adjusted. Its core value lies in the standardized pairing design, which solves the problem of a single bearing being unable to withstand bidirectional loads or requiring enhanced load-carrying capacity, while ensuring the coaxiality and preload consistency of the bearings in the group. It is widely used in machine tool spindles, precision motors, elevator traction machines and other scenarios with complex load directions and high stiffness requirements.

From a structural point of view, paired angular contact ball bearings are based on two sets of unidirectional angular contact ball bearings, and form three typical structures according to the difference in combination methods: one is the **back-to-back (DB) combination**, the wide sides of the outer rings of the two sets of bearings face each other, and the contact angle center line is in the shape of an "eight". The advantage is that it has strong resistance to overturning moments, and is suitable for scenes such as machine tool spindles that are susceptible to radial unbalanced loads; the second is the **face-to-face (DF) combination**, with two sets of bearing outer rings The narrow sides are opposite, and the contact angle center line is in the shape of an "X". It is characterized by high axial stiffness and is suitable for equipment that can withstand bidirectional axial loads and have high rotation speeds (such as servo motors). The third is the **tandem (DT) combination**. The narrow sides and wide sides of the outer rings of two sets of bearings are arranged in the same direction, and the contact angle center lines are parallel. This can increase the axial load-bearing capacity to 1.8-2 times that of a single set of bearings, and is suitable for one-way axial heavy load scenarios (such as elevator traction machines). Some matching components will integrate spacers (to adjust the preload force) or positioning sleeves to reduce the adjustment process during installation. The cages of the bearings in the group are mostly made of brass (suitable for high speed), and the rolling elements can be steel balls or ceramic balls (to improve wear resistance).Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
