Components of High Precision Matched Angular Contact Ball Bearings
 

Outer and inner rings

The inner ring fits over the shaft that the bearing connects to. The outer ring is the bearing's exterior. It contains and protects the bearing's components

Raceways

Angular contact bearings have inner and outer raceways. The outer raceway is asymmetrical to form the inclined contact angle.

Balls

The rolling elements are spherical. They move along the raceways to reduce friction in the bearing.

Cage

The cage is a separator in the raceway to keep the balls evenly spaced.

FAQ

 

Q: How do I know if the matched set fits my shaft/housing?

A: (1) Bearing model (e.g., 7008AC/DB);
(2) Shaft diameter;
(3) Housing inner diameter.

Q: What's the difference between P4 and P5 grade for my small CNC machine?

A: P4: For ultra-precise tasks (e.g., high-speed milling), better for tight tolerances.
P5: For general high-precision use (e.g., standard turning), more cost-effective.

Q: How long do matched sets usually last in daily use?

A: 1–3 years on average.

Q: Can I store matched sets for a long time?

A: Yes. Store them in a dry, dust-free area (temperature 5–25°C, humidity <60%) and avoid stacking heavy objects on the packaging. Shelf life is 2–3 years.

Q: How to preload an high precision matched angular contact ball bearing?

A: This is achieved by stick out grinding the bearing components at a fixed axial applied load, such that the inner and outer ring faces are flush with each other within a set axial force tolerance.

Q: What are the applications of high precision matched angular contact ball bearings?

A: Angular contact bearings are used in applications with combined radial and axial loads, high speeds, and high precision, such as machine tool spindles, electric motors, gearboxes, pumps, wind turbines, automotive components, and aerospace systems. Their ability to support significant axial loads in conjunction with radial loads makes them ideal for demanding, high-performance machinery requiring rigidity and accuracy.
