Bronze Plain Bearings
WE MANUFACTURE SLIDING BEARING FOR COMPREHENSIVE ASSEMBLY FOR
RAILWAYS.
Graphite Filled Bronze Bushes Flange Cast Bronze Solid Lubricant
Bearings Standard Size Chemical Resistant
We are offering our clients premium quality Graphite Filled Bronze Bushes, which is self-lubricant and maintenance free. Provided bushes are
machined out of continuous cast bronze and plugged with solid
lubricant plugs. These bushes are an excellent service and wear
resistance. Provided bushes used where normal oil and grease
lubricants do not work with corrosive liquids and gases and where
contamination by conventional lubricants is undesirable. Our
provided Graphite Filled Bronze Bushes exhibits an excellent
service and wear resistance.

Characteristics
TOB-50 Flange
1. May work without any ol for long period
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
where oil film is hard to be formed
5. Good chemical resistant and anti-corrosion characteristics
6. Can b€ used in wide range of temperature from -40℃-+300℃
Strusture
TOB-50 Flange 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 self-lubrication. The bearing shows
excellent performance without pre-lubrication under conditions of
extreme high/low temperature with low speed. This material provides
a maintenance-free bearing solution, particularly for high load,
intermittent of oscillating motion.

Typical Applications
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. It is widely 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...
