Product Description
The 6203-2RS is a double rubber-sealed, deep groove radial ball bearing with 17 mm inner diameter, 40 mm outer diameter, and 12 mm width, widely used in motors, machinery, and conveying systems for radial and light axial loads. Manufactured to ISO 492 standard, it is rated for dynamic load to 9.95 kN and static load to 4.75 kN, and is available with various cage and seal options. Multiple cross-reference part numbers are available for direct replacement.

Frequently Asked Questions
Q: What are the dimensions and load ratings of the 6203-2RS bearing?
A: The 6203-2RS has a 17 mm inner diameter, 40 mm outer diameter, and 12 mm width. It is rated for dynamic loads to 9.95 kN and static loads to 4.75 kN per ISO 492 standard, making it suitable for radial and light axial loads in material handling equipment.
Q: What do the 2RS seals provide?
A: The 2RS designation indicates dual rubber seals on both sides. These seals protect the bearing raceway and balls from dust, dirt, and moisture common in warehouse environments, extending bearing life and reducing maintenance intervals.
Q: What cross-reference part numbers are equivalent to the 6203-2RS?
A: The 6203-2RS replaces 6203RS, 6203LLU, 6203LLB, 6203DDU, 6203VV, 6203.2RSJ1, 6203EE, 6203.2RU, 6203LHX3, 203PP, 203KSZZ, 6203-2NSL, 99203, 6L025, 5972K44, 6153K77, 6203-2NSE, 6203.2RSR, and 62032RS. These are direct replacements for legacy equipment requiring this bearing size.
Q: Is the 6203-2RS suitable for motors and conveying systems?
A: Yes, the 6203-2RS is used in motors, machinery, and conveying systems in addition to manual pallet jacks. Its ISO 492 compliance and sealed design make it a standard choice for radial load applications across multiple equipment types.
Q: What materials is the 6203-2RS made from?
A: The 6203-2RS is manufactured from hardened chrome steel with races and balls hardened to resist wear. The dual rubber seals are elastomer material designed to maintain contact with the bearing shoulder throughout equipment service life.
