N313-E-XL-M1-C3
Holding a bearing marked NSK N313WC3? Ours is N313-E-XL-M1-C3 — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
N313-E-XL-M1-C3 is a cylindrical roller bearing with a 65 × 140 × 33 mm seat, execution: open · clearance C3. The manufacturer's cross-reference catalogue confirms full interchangeability for the designation NSK N313WC3.

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.
