Metal Materials

JDB650 material is made of strong cast bronze based metal with special solid lubricants embedded. It basic material is CuZn24Al6. 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.

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

Solid Lubricants

Lubricant	Features	Typical application
SL1 Graphite + add	Excellent resistance against chemical attacksandIowfriction.Templimit400℃	Suite for general machines and under atmosphere
SL4 PTFE + MOS2 + CF	Lower in friction and good for water lubrication,Temp.limit300℃	Ship, hydraulic turbine, gas turbine etc.

Feature

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

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...
