- 03Bore
- Bore 17 mm: by standard, 03 designates 17 mm.
- CSuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6303 is the standard ISO basic designation, which sets the bearing type, series and bore.

For equipment that needs a straightforward, reliable support, the FAG -C series deep groove ball bearing is a single row design with a sheet metal cage. It handles moderate radial and axial loads in both directions. You will find it in electric motors, pumps, fans, gearboxes and other power transmission applications. MR Industrial Accessories supplies this line and assists you in pinpointing the exact part number for your job.
The part number tells the story. The base number sets the size: 629-C, 6000-C, 6001-C, 6002-C, 6004-C, 6005-C, 6006-C and 6007-C all belong to the series, with bore diameters increasing as the number rises. The -C suffix marks a design variant within the deep groove ball bearing family. For precise dimensions, tolerances and clearance, check the manufacturer's data sheet or send us the full part number.
These bearings show up in a wide range of industrial equipment: electric motors, centrifugal pumps, fans, compressors, machine tools, conveyors and gearboxes. They also suit low and medium power applications where a simple, cost-effective and dependable support is required. Because the design is open, they need lubrication and a reasonably clean environment to perform as intended.
When choosing a bearing, consider the radial and axial load it will carry, the rotation speed and the lubrication method. During mounting, check alignment between housing and shaft, and apply force to the correct ring. If the equipment sees dust, moisture or frequent washdowns, a sealed version may be better. Correct lubrication and the right internal clearance are essential for service life.
On interchangeability: single row deep groove ball bearings can be swapped between manufacturers when the principal dimensions and design type align. The same size may carry different suffixes across brands, reflecting cage, sealing, clearance or tolerance differences. Do not replace based on visual similarity alone; compare the complete designation and operating conditions before deciding on a substitute.
If you already know the bearing part number, send it via WhatsApp or email to MR Industrial Accessories for a prompt quote. If you do not have it, share the shaft and housing dimensions, load type and working conditions, and we will help you identify the right option within the FAG line.
