Engineered for demanding agricultural machinery, heavy conveyor systems, and robust industrial power transmission assemblies, the CSA209 45mm eccentric locking collar insert bearing combines precision 45mm x 85mm x 43.7mm dimensions with secure eccentric collar locking. Designed for fast, reliable shaft mounting under heavy unidirectional loads, it acts as an exact direct replacement for PT International CSA209-45MM, AELS209-45MM, YET209-45, and KHR209-45. (Note: Also frequently referenced alongside 40mm x 80mm equivalent series such as PT International CSA208-40MM, AELS208N, YET208, KHR208, and RA108).
