1621-2RS Ball Bearing

The 1621-2RS Ball Bearing is a deep groove ball bearing with double rubber seals engineered for applications requiring contamination protection, quiet operation, and dependable performance in rotating systems.

Manufactured from chrome steel and factory pre-lubricated, this model combines low maintenance with efficient operation in industrial and mechanical equipment. The 2RS seal configuration helps preserve internal lubrication while reducing exposure to dust, moisture, and external debris.

Features of the 1621-2RS

The 1621-2RS belongs to the deep groove ball bearing family, widely used for applications involving radial loads and moderate axial loads.

Rubber seals on both sides help retain lubrication and reduce wear caused by external contamination. This style of bearing is commonly selected for systems requiring dependable operation and reduced maintenance intervals.

Common Applications

The 1621-2RS can be used in:

• Electric motors
• Agricultural equipment
• CNC machinery
• Conveyor systems
• Power tools
• Automated equipment
• Pulleys and reducers
• Light industrial machinery

Additionally, 1600 series bearings are widely used in equipment requiring continuous operation and low rotational resistance.

Benefits of the 1621-2RS Ball Bearing

Improved contamination protection

The 2RS seal helps block dust, moisture, and debris that could reduce bearing life.

Quieter operation

Deep groove design supports reduced vibration and smoother operation.

Reduced maintenance requirements

Factory lubrication helps simplify installation and reduce initial maintenance.

Stable mechanical performance
