Angular Contact Ball Bearings
Overview
- Angular contact ball bearings are engineered to carry combined radial and axial loads by utilizing a precisely ground raceway with a defined contact angle—typically 15°, 25°, or 40°. Unlike deep groove bearings with near-zero contact angles, this geometry enables superior axial load capacity and improved stiffness under demanding operating conditions.
- Talos Bearing supplies ISO 15 boundary dimension angular contact ball bearings in both standard and high-precision grades (P5 / P4). These bearings are designed for a wide range of industrial applications, from general-purpose pumps and gearboxes to high-speed CNC spindle systems operating at elevated dn values, where accuracy, rigidity, and thermal stability are critical.
- The range covers both single and matched set configurations, enabling engineers to optimize performance for speed, load distribution, and system rigidity in advanced mechanical designs.

Product Series Table
Single-Row 70 / 72 / 73
The most common configuration. Supports combined radial load and axial load in one direction. Often arranged in matched pairs (DB, DF, DT) for bidirectional capacity.
| Series | Bore Range | Contact Angle | Configuration | Typical Application |
|---|---|---|---|---|
| 70.. (Extra Light) | 4–200 mm | 15° / 25° | Single, or paired (DB/DF/DT) | High-speed spindles, small motors |
| 72.. (Light) | 8–200 mm | 15° / 25° / 40° | Single, or paired (DB/DF/DT) | Pumps, gearboxes, machine tools |
| 73.. (Medium) | 10–200 mm | 15° / 25° / 40° | Single, or paired (DB/DF/DT) | Conveyors, agricultural machinery |
Double-Row 32 / 33
A single integrated unit equivalent to two single-row bearings arranged back-to-back. Handles radial load plus axial load in both directions within a more compact axial footprint than a duplex pair.
| Series | Bore Range | Contact Angle | Configuration | Typical Application |
|---|---|---|---|---|
| 32.. | 10–200 mm | 30° | Integral double-row | Wheel hubs, pumps, gearboxes |
| 33.. | 15–110 mm | 30° | Integral double-row (wider) | Higher radial load applications |
Four-Point Contact QJ2 / QJ3
Single-row design with a split inner ring, allowing the balls to contact the races at four points. Supports heavy axial load in both directions plus radial load — in the same axial footprint as a single-row bearing.
| Series | Bore Range | Contact Angle | Configuration | Typical Application |
|---|---|---|---|---|
| QJ2.. | 10–140 mm | 35° | Split inner ring, single row | Compact bidirectional thrust + radial, gearboxes |
| QJ3.. | 15–160 mm | 35° | Split inner ring, single row (heavier) | Heavy machinery, pumps, compressors |
Quick Selection Guidance
- Axial load in one direction only, often at high speed: Single-row (70 / 72 / 73 series)
- Axial load in both directions, space isn't tight: Single-row pair (DB) or Double-row (32 / 33 series)
- Axial load in both directions, space is limited: Four-point contact (QJ series) — same footprint as a single-row bearing
