SKF 6312/C3 Open Deep Groove Ball Bearing
The SKF 6312/C3 is an open single row deep groove ball bearing designed for smooth rotation and effective shaft support in industrial equipment. It accommodates radial loads and axial loads in both directions while maintaining low friction. Its increased internal clearance makes it suitable for assemblies where C3 clearance is specified.
Design and Construction
The SKF 6312/C3 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 strength and effective load support under suitable operating conditions. With dimensions of 60x130x31mm, the bearing offers a substantial cross section for machinery requiring the 6312 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 rolling elements against contamination and prevent lubricant loss.
Applications
The SKF 6312/C3 can be considered for machinery where its dimensions, load capacity and increased internal clearance meet the operating requirements.
Industrial electric motors
Pumps and fluid handling equipment
Industrial fans and blowers
Conveyor drive assemblies
Gearboxes and mechanical transmissions
General industrial rotating machinery
Benefits
The SKF 6312/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.
Robust Construction: Its substantial 6312 series cross section provides effective load support under suitable operating conditions.
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 60x130x31mm dimensions and C3 radial internal clearance match your equipment requirements.
Check operating loads and speeds alongside shaft and housing fits. Lubrication and exposure to contamination should also be considered.
If normal internal clearance is required, the SKF 6312 may be more suitable. For machinery requiring integrated sealing, check the corresponding sealed or shielded SKF 6312 variants.
