Products Description

Angular Contact Ball Bearings (ACBB) are engineered to handle combined radial and axial loads simultaneously with exceptional precision. Featuring a defined contact angle (typically 15°-40°), they deliver superior rigidity, high-speed capability, and accurate shaft positioning – making them critical for applications demanding minimal deflection and maximum rotational accuracy.

TP’s ACBB series combines advanced materials, optimized internal geometry, and ISO-certified manufacturing to ensure unmatched performance in industrial automation, robotics, machine tools, and high-performance drivetrains.

Angular Contact Ball Bearings Type

Types	Features
Single-Row Angular Contact Ball Bearings	Designed to accommodate combined radial and axial loads in one direction. Common contact angles: 15°, 25°, 30°, 40°. Often used in paired arrangements (back-to-back, face-to-face, tandem) for higher load capacity or bidirectional load handling. Typical Models: 70xx, 72xx, 73xx series.
Double-Row Angular Contact Ball Bearings	Functionally similar to two single-row bearings mounted back-to-back. Can support axial loads in both directions along with radial loads. High rigidity and space-saving design. Typical Models: 32xx, 33xx series.
Matched Angular Contact Ball Bearings	Two or more single-row bearings assembled together with specific preload. Arrangements include: DB (Back-to-back) – for moment load resistance DF (Face-to-face) – for shaft alignment tolerance DT (Tandem) – for high axial load in one direction Used in precision machine tools, motors, and spindles.
Four-Point-Contact Ball Bearings	Designed to handle axial loads in both directions and limited radial loads. Inner ring split into two halves to allow four-point contact. Common in gearboxes, pumps, and aerospace applications. Typical Models: QJ2xx, QJ3xx series.
