Characteristics:
1/ Item: High frequency quenching; Carburizing and quenching; Whole quenching
2/ Application: Excavator, Loader, Crane; Excavator, Heavy duty Loader; Loader
Normal bearing:
Oiling grooves is normally used for bearing to reserve oil and lubricate the sliding surface, the disadvantage is:
1. Reduced the loading ability in reserving and distributing oil process, and reduced using life.
2. The oil can not well-distributed, leading lubricating blind zone and sliding surface easily occlusion together.
3. Oil reserve ability is finite, need frequent maintenance in the using life.
HDSLB overcome the above disadvantages, and its distinguishing feature is,
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.
Application:
Excavator ,rotary drilling machine,heavy duty loader,Diaphragm Wall Grab
Surface quenching
\ After quenching and tempering heat treatment binding with surface high frequency quenching process, giving product
Copper-steel bimetal sleeves normally be used for concrete mixer's joint, but it has following shortages:
ã??ã??1\ lower surface hardness, weak wearability,
ã??ã??2\lower tensile strength, easy broken under heavy load,
ã??ã??3\for hasped sleeves, defection sometime happened on hasp position.
Thin wall steel sleeves can solve above-mentioned problem, good effect easily get under low speed and heavy load condition.
Definition: wall thickness of quenching steel sleeve between 2.0 to 3.0mm.
Application:
1\ high basal toughness, higher internal surface hardness, shock resistance and wear ability are highly improved.
2\ due to the Vulcanizing or Phosphatizing treatment, friction factor is largely reduced to avoid early wearing failure.
3\suitable for heavy-duty working condition, replacing the bimetal sleeves and has been lot used on concrete mixer
