Review: See stars - great
Review: Good quality bearing for limited clearance - These bearings were used to replace worn sleeve bearings for small lathe handwheel shafts. The small size outer race was appropriate for the minimal clearance available. The application is shaft stabilization in low speed application and for that purpose, these bearings are entirely satisfactory.

## Features

- COMPACT SIZE: This miniature bearing features an ultra-compact design with an inner diameter of 8 mm, outer diameter of 12 mm, and width of 3.5 mm, making it ideal for applications with limited installation space.
- CAGELESS DESIGN: No retainer cage, full ball construction for higher radial load capacity, ideal for low-speed free spinning applications.
- SMOOTH PERFORMANCE: The balls inside these bearings roll nearly friction-free. You’ll often find them on rapidly rotating parts, from the whirring chuck on a power drill to the spinning shaft on an electric motor.
- DOUBLE SHIELDED: Double Shielded closures have a shield on both sides to protect the rolling elements from dust and debris, but allow lubricants to get in. Shields are made of metal and are not limited by speed or high temperature conditions.
- BEARING STEEL: Bearing steel cage material is durable and wear resistant in applications where corrosion is not a concern. Bearing steel ring material resists corrosion when exposed to damp or harsh environments.
- APPLICATIONS: Radial ball bearings provide support and alignment for rotary motion elements to run smoothly, such as a wheel on an axle. Ball bearings reduce friction which causes noise, vibration, and wear. They are found in a wide variety of equipment that have rotary motion elements such as in machine tools, pumps, motors, and conveyors.
