wear resistance, elastic limit has a direct impact.

Hardness is an important quality cylindrical roller bearings quality of contact fatigue strength , wear resistance, elastic limit has a direct impact. Cylindrical roller bearings use steel in general to reach a state of hardness HRC61 ~ 65, in order to make contact with koyo bearings get higher fatigue strength and wear resistance.
Manufacture of nylon 46 cage , reducing the ball and keep the sliding friction between the rack . Also, the rotational direction to eliminate the uneven shape , thereby reducing the ZYS taper roller bearings agitation loss . Further, the shape of the stress can be used to slow the time of assembly to ensure the performance of the assembly . The loss of a single cage 30 to reduce the torque of 40% , cylindrical roller bearings reduce torque loss of the overall 50 to 65% . The company speculated that the Prius will be 10 models and 15 mode fuel efficiency from the ZYS Precision Bearing previous 35.5km / L increased to 38.0km / L, improved fuel efficiency of about 1-2% is obtained through the use of such bearings .
koyo bearing parts in the production process , to go through a lot of cold , heat processing procedures , in order to meet the high-volume , high efficiency, high quality requirements , cylindrical roller bearing steel should have good processing performance. For example , hot and cold formability, machinability , hardenability and so on.
