1603-2RS Ball Bearing

The 1603-2RS Ball Bearing is an imperial-size deep groove ball bearing engineered for compact applications requiring stable rotation, lubrication protection, and consistent performance in continuous-duty equipment.

Widely used in small motors, power tools, automated systems, and light industrial equipment, the 1603-2RS belongs to the inch-series bearing family commonly applied in machinery built with imperial dimensions. Its double rubber seals (2RS) help preserve internal grease while reducing exposure to fine dust and light contaminants, contributing to longer operational service life. 

Manufactured from hardened chrome steel and supplied factory pre-lubricated, the bearing delivers reduced vibration, quiet operation, and dependable mechanical efficiency in compact rotating applications. 

Common Applications for the 1603-2RS

The 1603-2RS is frequently used in compact equipment requiring smooth operation and reduced maintenance, including:

• Small electric motors
• Power tools
• Automated equipment
• Compact machinery
• Light conveyor systems
• Agricultural equipment
• Industrial fans
• Precision systems

The 1600 Series is recognized for combining compact sizing, operational stability, and dependable capability in continuous-duty applications.
