6305-2RS Ball Bearing

The 6305-2RS Ball Bearing is a deep groove ball bearing with double rubber seals designed for industrial applications requiring smooth operation, mechanical durability, and dependable performance in high-speed rotating systems.

Measuring 25x62x17mm, this bearing is manufactured from chrome steel and supplied factory pre-lubricated to provide stable operation under radial loads and continuous use. The 2RS configuration uses rubber seals on both sides of the bearing to help preserve internal lubrication while reducing exposure to dust and moisture during operation.

Applications for the 6305-2RS

The 6305-2RS can be used in a variety of industrial and mechanical systems, including:

• Electric motors
• Industrial pumps
• Industrial machinery
• Conveyor systems
• Agricultural equipment
• Industrial fans
• Gearboxes and transmissions
• Automotive equipment

6300 series bearings are widely used in applications requiring increased load capacity and stable continuous operation.

Features of the 6305-2RS Ball Bearing

Double rubber seals

The 2RS configuration helps retain internal lubrication while reducing exposure to external debris and moisture.

Smooth operation

Deep groove design supports lower vibration, reduced friction, and efficient high-speed performance.

Chrome steel construction

Chrome steel provides dependable mechanical strength and long-lasting industrial durability.

High-speed support

This bearing is suitable for equipment operating under higher RPM and continuous use.

When to Use a 2RS Bearing

2RS bearings are commonly recommended for:

• Moderately dusty environments
• Equipment exposed to occasional moisture
• Continuous industrial systems
• Applications requiring improved lubricant retention

ZZ bearings are generally preferred for lower rotational resistance and cleaner environments.

Usage Recommendations

To help maximize bearing life:

• Check shaft alignment
• Avoid excessive impact loads
• Monitor operating temperature
• Keep the system clean
• Inspect vibration and noise regularly
