This document is an industrial bearing maintenance manual, which includes precautions for the maintenance and operation of industrial bearings. The manual provides information on bearing types, internal clearance, requirements for shafts and bearing seats, lubrication and sealing, etc.
The manual gives detailed safety warnings for bearing maintenance, such as never using compressed air to spin bearings, not disassembling assembled bearing sets, and clearing all lubricants before heating. It also recommends using a low‑carbon steel bar (1010 or 1020) for removal to avoid fragment ejection.
It covers general bearing handling and inspection, internal clearance, shaft and housing requirements and tolerances (ABMA standard), and specific sections for tapered roller, self‑aligning roller, cylindrical roller, thrust and ball bearings. Additional chapters describe maintenance tools and proper lubrication and sealing procedures, including seal installation tolerances and leak checks. This manual is written in Chinese.
