Cast bronze with graphite oilless bearings
650# material is made of strong cast bronze based metal with
special solid lubricants embedded. The base metal withstands
high load and the solid lubricants provide for self-lubrication.
The bearing shows excellent performance without pre-lubrication
under conditions of extreme high/lower temperature with low
speed.
This material provides a maintenance-free bearing solution,
particularly for high load, intermittent of oscillating motion.
|
1.May work without oil for long perlod
2.Extremely high load capacity,good anti-wear and lower friction
3.Particularly appropriate for low speed and high load
4.Suitable for reciprocating,oscillation or Intermittent motion
whereoil film is hard to be formed
5.Good chemical resistant and anti-corrosion characteristics
6.can be used in wide range of temperature from -40°c~+300°c |
|
|
Typical
Application |
This kind of bearing can be applied
under dry, high temperature, high pressure, corrosive, water
or other chemical environments when no oil can be introduced.
Now is widely be used in automotive products line, water engineering,
dam gate, plastic industries, successive casting machines, steel
rollers in metallurgy industry, mineral machines, ships, turbo
generators, hydraulic turbines and injection molding machines... |

For special heavy load application, CSB also can supply the
strong cast bronze of special high hardness. The material can
be up to HB>270, HB>300.
