Features

• The asymmetrical shape (crescent shape) sliding surface is given a special shape with texture and tapered land.
• The reduction of the outer circumference is reduced by reducing the rigidity due to the thinning of the cut section and the improvement of the expansion force by thickening the anti-cut part.
• The special shape of the sliding surface, textured and tapered, enables low torque.
• Durability is also improved by the formation of an oil film on the sliding surface.
