It Is With A Special Formulation Of High-Strength Bronze C86300/C86200 Or Copper Alloy With Good Casting And Dynamic, Corrosion-Resistance Properties. Its Surface Is Embeded With Self-Lubrication Graphite Arranged At Certain Angle And Density. It Is Typically Used In Injection Molding Machines, Mining Machinery, Heavy Duty Machinery, Bulldozer, Excavator, Auto Stamping Die, Plastic Mold, Preform Mold Etc.
1, no oil lubrication or less oil lubrication, can not be used for
refueling or difficult to refuel the place, can be used in the
maintenance or less maintenance.
2, wear resistance, friction coefficient, long service life.
3, there is the right amount of elastic-plastic, can stress
distribution in a wide contact surface, improve the bearing bearing
capacity.
4, static and dynamic friction coefficient is similar to the crawl
at low speed to eliminate, so as to ensure the accuracy of
mechanical work.
5, can reduce mechanical vibration, reduce noise, prevent
pollution, improve working conditions.
6, in the course of operation can form a transfer film, play a role
in protecting the grinding shaft, no bite axis phenomenon.
7, for the grinding shaft hardness requirements are low, not
quenched and tempered shaft can be used, thereby reducing the
processing of the relevant parts difficult.
ROLLED DRY SLIDING BEARINGS (PTFE)
Steel + Bronze Powder + PTFE/Fibre(DU)
Wrapped PTFE Lined (maintenance-free), self lubricated plain or flanged bearings, thrust washer and strip, Carbon steel shell with sintered bronze layer filled with PTFE
Bushing material suitable for lubricated applications
self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
Anti-friction bearing suitable for linear, oscillating and rotating movements
Material is designed to operate without supplemental lubrication and will perform excellent when lubrication is present. Low friction, low wear rate, good sliding characteristics and very low absorption are a few of the features of this material. VSB-10 bushings will support rotary, linear and oscillating motion.
1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the
rotating shaft. Minute partides of the PTFE layer and the sintered
bronze material combine to create a solid lubricant film, which
coats the shaft.
2. Sintered bronze powder thickness 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. Low-carbon steel backing. Setting the foundation of the bushings, the steel back provides
exceptional stability, load carrying and heat dissipation
characteristics.
