1. Seal-less sleeves, core shape blind holes,oil pits, are even distributed on the internal surface.
2. The oil pits has perfect oil reserve ability 3-5 times than normal oil grooves, it can last long time without maintenance.
3. Oil pits is evenly distributed in the bearing internal face, only need a little sliding action, oil can be supplied without lubricating blind zone.
4. The oil pits do not reduce the bearing loading ability and the bearing's using life is prolonged.
5. It is a new generation product used for engineering machine.(Patent No.ZL 2007 2 0103009.0 )
