Bearing 6304 RS shielded single-row deep groove ball bearing

Shielded 6304 RS single-row deep groove ball bearing designed to provide reliable radial support and accommodate moderate axial loads in both directions. The RS shield protects internal components from dust and light contaminants while helping retain lubricant, making this bearing suitable for applications where occasional exposure to debris occurs and where service intervals should be extended. Typical installation positions include shafts in electric motors, gearboxes, pumps, and general industrial rotating equipment.

Advantages

This single-row deep groove ball bearing offers compact design, low friction, and dependable rotational accuracy under radial loads. The RS shielding reduces ingress of contaminants and slows lubricant loss, which lowers maintenance frequency. Its construction supports smooth operation at moderate speeds and provides straightforward mounting and replacement in common mechanical assemblies.

Suitable for

• Electric motors and alternators
• Gearboxes and transmission assemblies
• Agricultural and construction machinery components
• Pumps, fans, and blowers
• General industrial rotary shafts and housings

Key specifications

• Bearing type: single-row deep groove ball bearing with shields
• Shielding: RS (shielded on one or both sides depending on variant) to reduce contamination and retain lubricant
• Load support: designed for radial loads and moderate axial loads in both directions
• Operating characteristics: low friction profile for smooth rotation at moderate speeds
• Typical materials: steel races and balls with rubber or metal shields and internal lubricant
• Mounting: designed for press-fit on shaft and in housing seats typical for this bearing class

How to use

Before installation, verify shaft and housing dimensions and ensure mating surfaces are clean and free of burrs. Fit the bearing using appropriate tools to apply force only to the correct ring to avoid damaging rolling elements or shields. After seating, check for free rotation and correct axial play. If additional sealing or lubrication is required for the application, follow equipment manufacturer guidelines. Avoid exposing the bearing to high-pressure washing or heavy contamination without additional protection.

Usage recommendations

For longer service life, use correct tolerances for shaft and housing fits, maintain proper lubrication levels, and avoid shock loads during assembly and operation. Replace bearings showing signs of excessive wear, noise, or vibration to prevent secondary damage to machinery.
