Q: Which brands make a 6001 bearing, and do they interchange?

Short answer: SKF, NSK, FAG, NTN and Timken all list a 6001 with identical ISO boundary dimensions (12 × 28 × 8 mm). They interchange by size, not by performance class. Match the suffix before you substitute: 2RS vs ZZ, C3 vs standard clearance, P0 vs P5 all change behaviour while keeping the same number.
