MRC Series Conveyor Roller Bearing

inch / metric 2RS sealed heavy duty

The MRC Series conveyor roller bearing is a precision-engineered unit designed specifically for material handling applications. Constructed with a thick-walled outer ring and a double-row ball complement, this bearing provides high radial load capacity while maintaining low rotational friction. The bearing is factory-filled with high-temperature grease and sealed with dual-lip nitrile rubber seals (2RS) to prevent ingress of dust, moisture, and debris commonly found in conveyor environments. Available in both inch and metric bore sizes, the MRC series offers direct interchangeability with existing roller designs. Operating temperature range spans -30°C to +120°C, suitable for continuous operation in warehouses, distribution centers, and manufacturing facilities.

High radial load

Thick-walled outer ring and optimized ball complement support heavy loads in high-traffic conveyor systems.

2RS sealing system

Dual-lip nitrile rubber seals provide superior protection against dust, moisture, and debris in harsh environments.

Pre-lubricated

Factory-filled with high-temperature lithium grease, eliminating the need for initial lubrication and reducing maintenance.

Universal fitment

Available in both inch and metric bore sizes for direct replacement in existing conveyor roller designs.

Frequently asked questions

What is the recommended mounting method for MRC bearings?

Press the bearing into the roller tube using a mounting tool that contacts the outer ring only. Ensure the tube ends are deburred and clean before insertion. Use a press with controlled force to avoid damaging the seals or raceways.

How often should MRC bearings be relubricated?

MRC bearings are pre-lubricated for life under normal operating conditions. For high-speed or high-temperature applications, consult the manufacturer for relubrication intervals. Sealed variants should not be regreased as this can damage the seals.

Can MRC bearings be used in washdown environments?

Yes, stainless steel variants with enhanced sealing are available for washdown applications. Standard carbon steel versions are suitable for dry indoor environments only.

Storage

Store in original packaging in a dry, temperature-controlled environment. Humidity should not exceed 60% to prevent corrosion of precision surfaces.

Handling

Avoid dropping or impacting the bearing. Use clean gloves during handling to prevent contamination of the sealed surfaces.

Installation

Ensure the shaft or roller tube is within tolerance. Excessive interference can reduce internal clearance and cause premature failure.
