SKF 6301/C3 Open Deep Groove Ball Bearing
The SKF 6301/C3 is an open single row deep groove ball bearing designed to provide smooth rotation and efficient 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 rotating equipment where C3 clearance is specified.
Design and Construction
The SKF 6301/C3 features deep raceway grooves and a single row of steel balls guided by a sheet metal cage. Its bearing steel construction provides strength and supports effective load distribution under suitable operating conditions.
With dimensions of 12x37x12mm, the bearing provides a robust arrangement for assemblies requiring the standard 6301 bearing size.
C3 Internal Clearance and Open Design
The bearing features C3 radial internal clearance, providing greater clearance than a bearing with normal internal 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 the bearing from contamination and lubricant loss.
Applications
The SKF 6301/C3 can be considered for rotating equipment where its dimensions and increased internal clearance meet the operating requirements.
Electric motors
Machine tools
Industrial pumps
Packaging machinery
Fans and ventilation equipment
General industrial machinery
Benefits
The SKF 6301/C3 offers several practical advantages.
Low Friction: Supports smooth rotation while helping reduce mechanical energy losses.
C3 Internal Clearance: Helps accommodate reductions in operating clearance caused by shaft fits and temperature differences.
Combined Load Support: Accommodates radial loads and axial loads in both directions.
High Speed Capability: Its deep groove design supports efficient operation at relatively high rotational speeds.
Flexible Lubrication: Open construction allows direct grease or oil lubrication.
Robust Construction: Bearing steel components provide effective load support under suitable operating conditions.
Bearing Selection
Before purchasing, confirm that the 12x37x12mm dimensions and C3 radial internal clearance match your equipment requirements.
Operating loads and speeds should be checked alongside shaft and housing fits. Lubrication and contamination exposure are also important. If normal internal clearance or integrated sealing is required, a different SKF 6301 variant may be more suitable.
