Yanmar YANMAR - N21 -COLLAR THRUST - 139653-66840
The Collar Thrust is a precision-engineered thrust control component used in YANMAR N21 / 6N21 / 8N21 marine diesel engines to absorb and transmit axial loads within rotating or control mechanisms. It helps maintain correct component positioning and prevents excessive axial movement during engine operation.
Designed for heavy-duty marine diesel engine applications, this thrust collar enhances operational stability, reduces wear on mating parts, and contributes to the reliable performance of YANMAR N21, 6N21, and 8N21 engines.
