適用范圍：This SAE Recommended Practice describes STANDARD-DUTY and eXTREME-DUTY Pilot Bearing requirements and sizes for class 6, 7, and 8 on-highway trucks and buses that use diesel engines and manual transmissions. The recommendations may apply to a wide range of other pilot-bearing applications, such as agricultural, industrial, and construction equipment. This document establishes standards for pilot-bearing construction, tolerances, installation dimensions, and operating characteristics. It is intended to standardize installation dimensions for engine and transmission manufacturers, and identify minimum operating characteristics to ensure satisfactory bearing life in pilot-bearing application environment.
