SKF 6207/C3 Open Deep Groove Ball Bearing
The SKF 6207/C3 is an open single row deep groove ball bearing designed for smooth rotation and effective support of rotating shafts. Its deep raceway construction accommodates radial loads and axial loads in both directions while maintaining low friction. The increased internal clearance makes it suitable for assemblies where C3 clearance is specified.
Design and Construction
The SKF 6207/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 35x72x17mm, the bearing offers a smaller outside diameter and narrower profile than the 6307 series while retaining the same 35mm bore.
C3 Internal Clearance and Open Design
The bearing features C3 radial internal clearance, which is greater than normal clearance. This helps compensate for reductions in operating clearance caused by interference fits and temperature differences between the bearing rings.
Its open design without seals or shields allows grease or oil to reach the rolling elements directly. Suitable external sealing may be necessary to protect against contamination and lubricant loss.
Applications
The SKF 6207/C3 can be considered for rotating machinery where its dimensions and increased internal clearance meet the operating requirements.
Electric motors
Industrial pumps
Fans and ventilation equipment
Conveyor drive assemblies
Gearboxes and mechanical transmissions
General industrial machinery
Benefits
The SKF 6207/C3 offers several practical advantages.
C3 Internal Clearance: Helps accommodate reductions in operating clearance caused by interference fits and temperature differences.
Low Friction: Supports efficient shaft rotation while helping reduce mechanical energy losses.
Combined Load Support: Accommodates radial loads and axial loads in both directions.
Compact Bearing Profile: Provides a smaller outside diameter than the 6307 series for assemblies designed around the 6207 dimensions.
High Speed Capability: Its deep groove construction supports relatively high rotational speeds with appropriate lubrication.
Flexible Lubrication: Open construction allows direct grease or oil lubrication.
Bearing Selection
Before purchasing, confirm that the 35x72x17mm dimensions and C3 radial 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 is required, the SKF 6207 may be more suitable. For applications requiring integrated sealing, check the corresponding sealed or shielded SKF 6207 variants.
