1. Product Description
The Single Row Angular Contact Ball Bearing is engineered for high precision and speed applications where combined radial and axial loads are present. Manufactured by Adarsh Bearings Pvt. Ltd. under the Locus brand, these bearings are suitable for demanding industrial environments such as machine tools, gearboxes, motors, and pumps. They support thrust load in one direction and are often used in matched pairs.

3. Working Principle
The bearing consists of inner and outer rings, a row of balls, and a cage. It is designed with a non-perpendicular contact angle that enables it to withstand combined loads (radial + axial). The axial load is supported only in one direction, which means correct orientation during installation is crucial.
4. Principle
Angular contact bearings work on the principle of angular contact load distribution. The internal geometry is designed such that the ball-race contact points are aligned at an angle to the bearing axis, allowing axial force to be transmitted through the ball and inner/outer ring in one direction.

10. Frequently Asked Questions (FAQs)
Q1: Can Angular Contact Bearings take axial load in both directions?
→ No, single row bearings support axial load in one direction only. Use paired bearings for both directions.
Q2: Can I run these at high speed?
→ Yes. They’re designed for high-speed and precision use.
Q3: Are these suitable for vertical shafts?
→ Only when paired correctly (DF or DB configuration).
Q4: What preload options are available?
→ Light (L), Medium (M), Heavy (H) preload options available on request.
Q5: Are sealed options available?
→ Yes, options include Open, ZZ (Shielded), and 2RS (Rubber Sealed).
