Frequently Asked Questions
Q: What are the dimensions and specifications of the 6205RS bearing?
A: The 6205RS is a single-row deep groove ball bearing with a 25 mm bore, 52 mm outside diameter, 15 mm width, and dual contact rubber seals. It is manufactured from SAE 52100 hardened bearing steel with Grade-10 bearing chrome steel balls. The limiting speed under grease lubrication is 8400 RPM.
Q: What are the equivalent part numbers for the 6205RS?
A: The 6205RS is equivalent to 6205, 6205-Z, 6205-ZZ, 6205-RS, 6205-2RS, and 6205-NR. These designations represent open, shielded, and sealed variants of the same basic bearing. Verify seal type and clearance specifications when substituting between variants.
Q: Can the 6205RS handle both radial and axial loads?
A: The 6205RS is primarily designed for radial loads typical in wheel assemblies and rotating machinery. It can accommodate limited axial loads due to its deep groove design, but it is not rated as a thrust bearing. For applications with significant axial loading, verify that load requirements fall within bearing specifications.
Q: What is the bearing steel specification for the 6205RS?
A: The 6205RS is constructed from SAE 52100 bearing steel (hardened) with Grade-10 bearing chrome steel balls. This material provides high fatigue strength, hardness, and resistance to wear, making it suitable for manual pallet jack wheel assemblies and industrial pump applications.
Q: What RPM limit applies to the 6205RS?
A: The 6205RS has a limiting speed of 8400 RPM when operating under grease lubrication. This specification applies to typical manual pallet jack and light industrial duty applications. Speeds above this limit require oil lubrication and proper thermal management.
Q: What is the difference between 6205RS and open bearing variants?
A: The 6205RS features dual contact rubber seals (RS designation) that exclude contamination and retain lubricant. Open bearings like the 6205 provide lower friction and less heat generation but require a cleaner operating environment and more frequent lubrication maintenance.
