Single Row Angular Contact Bearing

1. Load & Mounting Performance
● Suited for combined radial‑axial loads and pure axial thrust conditions, well‑adapted to high‑speed rotating operating scenarios.
● Takes unidirectional axial loads. Note that radial loading induces secondary axial force while the bearing is running.
● Restricts one‑way axial displacement for shafts and housings when operated as a single unit bearing.
● Mount with a second bearing set to offset axial forces acting from the reverse direction.
● Supports back‑to‑back (DB) and face‑to‑face (DF) mounting layouts to cancel out residual axial forces.
● Matched paired installation enables bidirectional axial positioning for shafts and housings.

2. Rigidity & Structural Design
● Features a higher ball complement than same-size deep groove ball bearings, delivering superior load ratings, enhanced system rigidity, and smooth, stable operation.
● Radial internal clearance can be fine-tuned via relative displacement of the inner and outer rings; multiple bearings can be pre-loaded in parallel to further boost overall system stiffness.

3. Contact Angle & Clearance Configuration
● Built with a non-zero contact angle, available in standard industry sizes: 15°, 25°, 30°, and 40°.
● Larger contact angles provide increased axial load capacity, while smaller contact angles optimize performance for high-speed rotational applications.
● Individual bearings are manufactured with standard initial internal clearance; matched bearing sets are configured to achieve the required internal clearance for specific applications.
● Matched bearing assemblies are offered in two configurations to suit operational needs: preload (zero or negative internal clearance) and pre-set internal clearance.
● Preload matched sets are factory-calibrated with zero/negative clearance, ideal for machine tool spindles and other high-rigidity, high-precision applications.
