Why ratings are not copied
Load ratings and speed limits change with internal design, cage, seal, lubricant and manufacturer. The approved LTO data sheet governs the quotation.
Suffixes still matter
Clearance, precision, contact angle, bore, sealing and material suffixes must be matched before interchangeability is confirmed.
