6302RS Deep Groove Ball Bearings with Seal

The 6302RS Deep Groove Ball Bearings with Seal is a high-performance sealed rolling bearing designed for applications that require dustproof, waterproof and axial fixation.

Parameters

Core design features

1. Retaining ring groove structure

The outer ring has a standard retaining ring groove (circlip groove) to facilitate the installation of retaining rings or retaining rings to achieve axial positioning and prevent the bearing from shifting under high-speed operation or vibration conditions.

6302RS Deep Groove Ball Bearings with Seal is suitable for design scenarios where the shaft end is fixed or simplified installation is required.

2. Sealing performance

RS sealing ring: It adopts oil-resistant rubber (NBR) sealing layer and contact sealing design to effectively prevent dust, water vapor and fine particles from invading the bearing interior and extend the life of grease.

Applicable environment: humid, dusty or slightly polluted industrial environment.

3. Material and process

Bearing ring and steel ball: high carbon chromium steel (GCr15) quenching treatment, hardness up to HRC 60-64, with high wear resistance and fatigue resistance.

Cage: steel plate stamping cage (SPCC standard), lightweight and impact resistant, ensuring uniform distribution of steel balls.

4. Performance advantages

High load capacity: deep groove structure can bear radial load and bidirectional axial load at the same time

Low friction operation: precision grinding process ensures smooth raceway, with high-quality grease, low friction coefficient, suitable for high-speed application

Long life design: sealing protection + high carbon steel material, significantly reducing wear rate

Typical application areas

Motor and transmission system: industrial motor, reducer, power tool, fan motor.

Automotive parts: gearbox, water pump, generator, belt tensioner.

Household appliances: washing machine drum, air conditioner compressor, vacuum cleaner motor.

Industrial equipment: pumps, conveyor belt rollers, food machinery, agricultural machinery.

Installation and Maintenance Guide

1. Preparation before installation

Clean the shaft and bearing seat to ensure that there are no burrs or contaminants to avoid damaging the seal ring.

Check the matching of the retaining ring groove size and the retaining ring

2. Installation method

Use a mechanical press to install, and do not knock the seal side directly.

After installation, confirm that the retaining ring is fully embedded in the groove to provide stable axial fixation.

3. Lubrication and maintenance

Default pre-lubrication, no need to add grease under normal working conditions; when running at high temperature or high speed, lubricant can be added through the grease injection hole on the side of the seal ring.

Check the integrity of the seal ring regularly, and replace it in time if it is found to be aging or damaged.

Bearing preservation

Bearings are precise parts. In order to maintain the accuracy and reliability of bearings, they must be handled carefully during operation, especially to keep the bearings clean and avoid strong collisions and rust.

The 6302RS Deep Groove Ball Bearings with Seal produced by the company are all attached with rust inhibitors on the surface and should be stored at room temperature with a relative humidity below 60%.
