Product detailed description
6203 2RS NSK deep-groove ball bearing
NSK 6203 2RS is a single-row deep-groove ball bearing with dimensions 17 × 40 × 12 mm. The designation 2RS identifies contact rubber seals on both sides.
Technical data
| Bore diameter d | 17 mm |
|---|---|
| Outside diameter D | 40 mm |
| Width B | 12 mm |
| Type | single-row deep-groove ball bearing |
| Sealing | 2 contact rubber seals (2RS) |
| Brand | NSK |
Application and mounting
- Carries radial load and limited axial load in both directions.
- The two seals protect the bearing and help retain lubricant, but create more friction than an open or shielded design.
- Clean all seating surfaces before fitting; transmit force only through the ring being fitted with interference, never through the balls.
- After mounting, verify alignment, free rotation and operating temperature.
Important: Do not confuse 6203 2RS with open 6203, Z/2Z shielded versions or single-sealed RS. For C3 variants, also verify the required internal clearance.
