SKF 6205-2RSH Sealed Deep Groove Ball Bearing
The SKF 6205-2RSH is a sealed single row deep groove ball bearing designed for smooth rotation and effective shaft support in industrial machinery. It accommodates radial loads and axial loads in both directions while providing protection through integrated rubber contact seals.
Its factory grease lubrication and normal radial internal clearance make it a practical choice for equipment requiring the standard 6205 bearing dimensions with reduced routine maintenance.
Design and Construction
The SKF 6205-2RSH features a single row of steel balls running between deep raceway grooves. A sheet metal cage separates and guides the rolling elements during rotation.
Its bearing steel construction provides effective load support under suitable operating conditions. With dimensions of 25x52x15mm, it offers a smaller outside diameter and narrower profile than the 6305 series while retaining the same 25mm bore.
2RSH Contact Seals and 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 grease lubricated and sealed for low maintenance operation. Routine relubrication is not normally required.
It has normal radial internal clearance (CN) for applications where standard clearance is specified. Contact seals provide additional protection but introduce more friction than an open bearing.
Applications
The SKF 6205-2RSH can be considered for equipment where its dimensions, sealed construction and operating characteristics meet the machinery requirements.
Industrial electric motors
Pumps and fluid handling equipment
Industrial fans and blowers
Conveyor rollers and drive assemblies
Agricultural machinery
General industrial rotating equipment
Benefits
The SKF 6205-2RSH offers several practical advantages.
Double Contact Seals: Help retain grease and protect the rolling elements against contamination.
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 shaft support where a 25mm bore, 52mm outside diameter and 15mm width are required.
Smooth Rotation: Its deep groove raceways support efficient rolling motion under suitable operating conditions.
Normal Internal Clearance: Provides the standard clearance arrangement for machinery where normal clearance is specified.
Bearing Selection
Before purchasing, confirm that the 25x52x15mm dimensions and normal radial internal clearance match your equipment requirements.
Check operating loads and speeds alongside shaft and housing fits. Temperature, lubrication conditions and contamination exposure should also be considered when selecting the bearing.
If increased radial internal clearance is required, the SKF 6205-2RSH/C3 may be more suitable. For machinery requiring direct grease or oil lubrication, consider an appropriate open SKF 6205 variant.
