Designations are mostly standardized - verify the details

Deep groove ball bearings follow ISO 15 dimension series, so a 6205-2RS is a 6205-2RS whether it says SKF, FAG, NSK, NTN, TIMKEN or KMK. The interchange works for most catalog items:

Four checks before you substitute

• Clearance code: C3 vs normal changes with fit and temperature - match the application, not the label
• Precision class: spindle positions need P4/P2; confirm before switching
• Seal type: 2RS (contact) vs ZZ (non-contact) changes friction and speed limits
• Cage material: brass vs steel vs PA66 - matters at high speed or in washdown

Send the code, get the equivalent

Email us the original designation and quantity - we reply with the KMK equivalent, price and lead time. Mixed-brand consolidation through one supplier typically cuts sourcing cost 20-40% at equal specification. See all product categories or transmission chains for related power transmission parts.
