SKF 6203/C3 Open Deep Groove Ball Bearing
The SKF 6203/C3 is an open single row deep groove ball bearing designed for 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 machinery where greater operating clearance is required.
Design and Construction
The SKF 6203/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 efficient load distribution during operation. With dimensions of 17x40x12mm, the bearing provides compact shaft support while allowing efficient rotation at relatively high speeds.
C3 Internal Clearance and Open Design
The bearing features C3 radial internal clearance, which provides greater clearance than a bearing with normal internal 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 necessary to protect the bearing against contamination and lubricant loss.
Applications
The SKF 6203/C3 can be considered for rotating equipment where its dimensions and C3 clearance meet the operating requirements.
Electric motors
Industrial pumps
Fans and ventilation systems
Gearboxes and mechanical drives
Conveyor equipment
General industrial machinery
Benefits
The SKF 6203/C3 open deep groove ball bearing 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 construction supports efficient operation at relatively high rotational speeds.
Flexible Lubrication: Open construction allows direct grease or oil lubrication.
Robust Construction: Bearing steel components provide strength and effective load support under suitable operating conditions.
Bearing Selection
Before purchasing, confirm that the 17x40x12mm dimensions and C3 internal clearance match your equipment specifications. Operating loads and speeds should be checked alongside shaft and housing fits. Lubrication and environmental conditions are also important. If normal internal clearance or integrated sealing is required, a different SKF 6203 variant may be more suitable.
