Identification before ordering
Confirm the exact SR2-5TLZWN model, GS-G1 P/N, all source dimensions and photographs of both bearing faces. The current card does not verify a handpiece brand, rotor model or replacement equivalence.
Use the dental bearing size chart, review the bearing model and P/N cross-reference, or submit evidence through bearing identification.
