SKF 6005/C3 Open Deep Groove Ball Bearing
The SKF 6005/C3 is an open single row deep groove ball bearing designed for smooth rotation and efficient shaft support. Its slim construction makes it suitable for rotating equipment with limited installation space where increased C3 internal clearance is required.
Design and Construction
The SKF 6005/C3 features a single row of steel balls running between precision manufactured deep raceway grooves. A stamped steel cage guides the rolling elements and maintains their separation during operation.
Its bearing steel construction provides strength and effective load support. With dimensions of 25x47x12mm, it offers a compact alternative for equipment requiring the standard 6005 bearing size.
C3 Internal Clearance and Open Design
The bearing features C3 radial internal clearance, which provides greater clearance than a bearing with 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 housing seals may be necessary to protect against contamination and lubricant loss.
Applications
The SKF 6005/C3 can be considered for rotating equipment where its dimensions and increased internal clearance meet the operating requirements.
Electric motors
Industrial pumps
Fans and ventilation equipment
Mechanical drive assemblies
Industrial transmission equipment
General rotating machinery
Benefits
The SKF 6005/C3 offers several practical advantages.
C3 Internal Clearance: Helps maintain suitable operating clearance where shaft fits or temperature differences reduce internal clearance.
Low Friction: Supports smooth 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 construction supports relatively high rotational speeds with suitable lubrication.
Flexible Lubrication: Open construction allows direct grease or oil lubrication.
Slim Construction: Provides effective shaft support where a smaller bearing outside diameter is required.
Bearing Selection
Before purchasing, confirm that the 25x47x12mm 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 or integrated sealing is required, a different SKF 6005 variant may be more suitable.
