# How to Specify B71910C Without Mixing Nearby Parts
Look-alike part numbers are the usual way a stores ticket goes wrong on a precision spindle angular contact ball bearing. Do not substitute B71911E, B71912C, or B71913E T.P4S.UL, which are grouped on the same title. This page should be treated as B71910C. Contact angle, preload, and precision suffixes on neighboring 7191x codes are not interchangeable.
