Title:
METHOD OF PRODUCING BEARING UNIT-USE OUTER RACE
Document Type and Number:
WIPO Patent Application WO/2007/125927
Kind Code:
A1
Abstract:
When both the outer race tracks (10c, 10b) of an outer race (2b) are to be ground where the diameter (DB1) of the first outer race track (10c) is larger than the diameter (DB2) of the second outer race track (10b) (DB1> DB2), a method of introducing a grinding tool (12) into the inside of the outer race (2b) easily is realized. As shown by (A)→(B), the grinding tool (12) is introduced into the inside of the outer race (2b) through an opening, out of the opposite openings of this outer race (2b), that is closer to the first outer race track (10c), whereby the above problem is resolved.
