B7210-E-T-P4S-UL
Holding a bearing marked SKF 7210ACDGA/P4A or NSK 7210ETSULP4 or KOYO 7210GLFGP4? Ours is B7210-E-T-P4S-UL — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
B7210-E-T-P4S-UL is a spindle bearing with a 50 × 90 × 20 mm seat, execution: open. The manufacturer's cross-reference catalogue confirms full interchangeability for 12 designations, including SKF 7210ACDGA/P4A, SKF 7210ACDGB/P4A, NSK 7210ETSULP4. For 2 designations (SKF 7210ACDGB/PA9A, KOYO 7210GLFGP4) interchangeability is conditional — the difference usually lies in radial clearance or cage design, so compare the data sheets before fitting.

Before you replace it
This is a dimensional and design equivalent: the same seat size, the same bearing type and the same sealing and clearance design. It is not the same product — load ratings, tolerance class and grease may differ between manufacturers. For duty close to the limits or a critical application, check the datasheet of the specific design.
The same seat in another execution
These items share the mounting size and have cross-reference tables of their own. They differ in sealing, clearance or cage — exactly what decides how the bearing behaves in the seat.
Where these equivalents come from
The base number of a standard bearing is an ISO standard — 6205 is 6205 at every manufacturer. Only the suffixes describing the design differ, and those are what we translate: shields, contact seals, cage and radial clearance. Designations that mean different things at different makers are deliberately omitted.
