In Copeland compressors (used in HVAC and refrigeration systems), bearing bushes/sleeve bushings are replaceable parts that support the motor/crankshaft inside the compressor crankcase and help reduce friction and wear between moving components. These are typically PTFE‑coated or precision machined bushes installed at the motor side or crankcase side of reciprocating or semi‑hermetic compressors.
Examples of such parts include part numbers like 035‑0035‑00 (end bush bearing) or various housing/bush assemblies used on different series of Copeland compressors.
