Water-Lubricated Journal Bearings ...Lowering costs and raising service life with no external lubrication and a reduction in maintenance work, everything delivered immediately from stock - that is the core idea and the objective of all viiplus polymer plain bearings.
Self-lubricating bearings are divided into composite self-lubricating bearings, solid mosaic self-lubricating bearing shaft, bimetallic materials
Self-lubricating bearings, special materials, self-lubricating bearings, according to different uses and conditions, use a different self-lubricating bearings.
One of the major categories of solid mosaic self-lubricating bearings (referred to as JDB) is a combination of metal bearing characteristics and characteristics of non-oil lubricated bearings, lubricated by the metal matrix to bear the load, the special formula of solid lubricating material.
It is characterized by high load-bearing capacity, impact resistance, high temperature resistance and self-lubricating ability. It is especially suitable for occasions where it is difficult to lubricate and form oil film, such as heavy load, low speed, reciprocating or swinging, and erosion of water and other acid And erosion. The products have been widely used in metallurgy continuous casting machine, rolling equipment, mining machinery, mold, lifting machinery, textile machinery, wind power generation, shipbuilding, steam turbine, turbine, injection molding machine and equipment production line. Wear resistance is double the normal sleeve.
Description
VSB-30
Hydrodynamic Composite Bearings
Steel Bronze Powder with PEEK/PTFE Marginal Bearings, provides maintenance-free operating, Temperature be allowance from -150 until +250°C, operate satisfactorily without lubrication under lieght duty and low speed, high static and dynamic load
Steel + Bronze Powder + PEEK/PTFE
CHARACTERISTICS
VSB-30
1 . VSB-30 provides maintenance-free operation
2 . Operate satisfectorily without lubrication under light duty and low speed
3 . VSB-30 has a high PV capability under high temperature
4 . Temperature allowance is from -150℃-+250℃
5 . Good chemical resistance
6 . High static and dynamic load capacity
7 . No water absorption
8 . Suitable for rotating , oscillating , reciprocating and sliding movement .
1.PEEK/PTFE 0.30~0.50mm. It has high wear resistance and low friction even only minute of lubricant are supplied. The bearing surface carries a pattern of circular indents which will be filled with grease on assembly of the bearing.
2.Bronze layer 0.20~0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.
3.Steel backing.Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
