SKF 6205/C3 Open Deep Groove Ball Bearing
The SKF 6205/C3 is an open single row deep groove ball bearing designed for smooth rotation and effective shaft support. It accommodates radial loads and axial loads in both directions while maintaining low friction. Its increased internal clearance makes it a practical choice for machinery where C3 clearance is specified.
Design and Construction
The SKF 6205/C3 features a single row of steel balls running between deep raceway grooves. A sheet metal cage separates and guides the rolling elements during operation.
Its bearing steel construction provides effective load support. The dimensions of 25x52x15mm make it suitable for assemblies requiring the standard 6205 bearing size.
C3 Internal Clearance and Open Design
The bearing features C3 radial internal clearance, which is greater than normal clearance. This helps accommodate reductions in operating clearance caused by interference fits and temperature differences between the bearing rings.
Its open design without seals or shields allows direct grease or oil lubrication. Suitable external sealing may be required to protect the bearing against contamination and lubricant loss.
Applications
The SKF 6205/C3 can be considered for equipment where its dimensions and C3 clearance meet the operating requirements.
Electric motors
Industrial pumps
Fans and ventilation equipment
Gearboxes and mechanical transmissions
Conveyor drive assemblies
Agricultural machinery
Benefits
The SKF 6205/C3 provides several practical advantages.
C3 Internal Clearance: Helps accommodate reductions in operating clearance caused by shaft fits and temperature differences.
Low Friction: Supports efficient rotation while helping reduce mechanical energy losses.
Combined Load Support: Accommodates radial loads and axial loads in both directions.
High Speed Capability: Its deep groove design supports relatively high rotational speeds with suitable lubrication.
Flexible Lubrication: Open construction allows direct grease or oil lubrication.
Effective Shaft Support: Bearing steel components provide strength and reliable load support under suitable operating conditions.
Bearing Selection
Before purchasing, confirm that the 25x52x15mm dimensions and C3 internal clearance match your equipment requirements.
Check operating loads and speeds alongside shaft and housing fits. Lubrication and contamination exposure should also be considered. If normal internal clearance or integrated sealing is required, a different SKF 6205 variant may be more suitable.
