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)
