6201 2RS 1/2" SMB Ball Bearing 12.7x32x10 mm

6201 2RS 1/2" SMB Deep Groove Ball Bearing 12.7x32x10 mm

6201 2RS 1/2" SMB is a sealed deep groove ball bearing designed for industrial applications requiring inch-size shaft compatibility, contamination protection, and long-term reliable operation.

Industrial applications

The 6201 2RS 1/2" SMB deep groove ball bearing is widely used in machinery where imperial shaft dimensions are required. Its 1/2 inch inner diameter makes it ideal for equipment designed to US and UK standards.

Typical applications include:

• electric motors and drive systems with 1/2 inch shafts
• conveyor systems and automation equipment
• agricultural and garden machinery
• workshop equipment and industrial tools

This bearing is especially useful in maintenance and retrofit operations where inch-based components are still in use.

Construction and design

This deep groove ball bearing features a classic single-row design optimized for versatility and durability. The 2RS sealing system provides rubber seals on both sides, protecting against dust, moisture, and contaminants while retaining lubrication inside the bearing.

Precision-ground raceways and high-quality steel balls ensure smooth rotation, reduced vibration, and stable operation even at higher speeds.

The combination of metric outer dimensions and inch inner diameter creates a hybrid solution for mixed-standard mechanical systems.
