Development aims
Positively generate oil film pressure
→Low friction in fluid area and expanded fluid lubrication area

Development concept
Leaked oil is drawn in to facilitate rapid warming up of the oil film
Conventional

Developed (Tapered)


A continuous tapered section and land section are provided to generate oil film pressure thanks to the wedge effect.

Performance
Friction loss

Seizure resistance

Improved friction resistance and seizure resistance over existing products
(Torque reduction: 0.13 Nm@1000 N, 1000 rpm; seizure resistance: approximately 3 times)
