Rubber Cutlass Bearings
Yuanfeng rubber cutlass bearings are engineered for marine propeller shaft systems. The bearing consists of a precision-machined metal shell (naval brass, stainless steel, or aluminum bronze) with a vulcanized rubber lining. The rubber absorbs vibration, reduces noise, and minimizes shaft sleeve wear.
Water lubrication eliminates oil leakage, a critical advantage under IMO environmental regulations.
Developed with technical guidance from Professor Han Yanfeng.
