[Features] · Pre-lubricated bearing. · Be sure to fill with lubricant before installing. · Supplying a small amount of lubricant at predetermined intervals allows the bearing to withstand long term operation. · The bearing has a structure where bronze in a spherical powdered form is sintered on to the steel backing and polyacetal resin is then impregnated into the surface. · Operation is quiet, free of squeaking or knocking. · Low friction characteristics prevents damage to the shaft (mating surface). · The bearing surface remains virtually wear-free with minimum amount of lubricant (grease or oil). · The frictional force at startup is extremely low. This enables smooth rotation at startup and at low speed under high load conditions. Superior non-seizure properties. · Shaft misalignment tolerance is excellent. · Can withstand impact loads. · Excellent load-carrying performance is maintained even under oscillating and fretting conditions.
