SKF 6302-2RSH/C3 Sealed Deep Groove Ball Bearing
The SKF 6302-2RSH/C3 is a sealed single row deep groove ball bearing designed for smooth rotation and effective shaft support in compact industrial machinery. It accommodates radial loads and axial loads in both directions while combining rubber contact seals with increased C3 internal clearance.
Design and Construction
The SKF 6302-2RSH/C3 features a single row of steel balls running between deep raceway grooves. A stamped steel cage separates and guides the rolling elements during rotation.
Its bearing steel construction provides strength and effective load support under suitable operating conditions. With dimensions of 15x42x13mm, it fits assemblies designed for the standard 6302 bearing size.
2RSH Contact Seals and C3 Internal Clearance
The 2RSH designation indicates rubber contact seals on both sides of the bearing. These help retain factory applied grease while restricting the entry of dust, moisture and other contaminants.
The bearing is supplied lubricated and sealed for low maintenance operation. Routine relubrication is not normally required.
Its C3 radial internal clearance is greater than normal clearance. This helps compensate for reductions in operating clearance caused by interference fits and temperature differences between the bearing rings.
Applications
The SKF 6302-2RSH/C3 can be considered for equipment where its dimensions, sealing arrangement and increased clearance meet the operating requirements.
Electric motors
Industrial pumps
Fans and ventilation equipment
Conveyor rollers and drive assemblies
Agricultural machinery
General industrial rotating equipment
Benefits
The SKF 6302-2RSH/C3 offers several practical advantages.
Double Contact Seals: Help retain grease and protect the rolling elements against contamination.
C3 Internal Clearance: Helps accommodate reductions in operating clearance caused by interference fits and temperature differences.
Low Maintenance: Factory grease lubrication and integrated seals reduce routine lubrication requirements.
Combined Load Support: Accommodates radial loads and axial loads in both directions.
Compact Construction: Provides effective shaft support where a 15mm bore and 42mm outside diameter are required.
Smooth Rotation: Deep groove raceways support efficient rolling motion under suitable operating conditions.
Bearing Selection
Before purchasing, confirm that the 15x42x13mm dimensions and C3 radial internal clearance match your equipment specifications.
Check operating loads and speeds alongside shaft and housing fits. Temperature, moisture exposure and contamination levels should also be considered. Contact seals provide additional protection but introduce more friction than an open bearing.
If normal radial internal clearance is required, the SKF 6302-2RSH may be more suitable. For machinery requiring direct grease or oil lubrication, consider an appropriate open SKF 6302 variant.
