Product Description

PTFE lined wrapped Bearings Boundary Lubricating Bushings Sleeve Bushes | VSB-10

High Performance, Low Wear Solutions

SELF-LUBRICATING BEARINGS SOLUTIONS

Viiplus range of PTFE lined wrapped bearings is suitable for dry running, low friction, low wear applications. These wrapped bearings have excellent sliding characteristics forming a transfer film that can protect the mating metal surface.
Our PTFE lined wrapped bearings have been developed for high duty, oil lubricate applications.

 

Self Lubricating Sleeve Bearings | Wrapped PTFE Lined Series Bearings 1/4 " ID x 5/16 " OD x 1/4 "

 
We are able to offer PTFE lined wrapped bearings in metric plain, imperial plain, metric flanged, metric washers, imperial washers, metric strip and imperial strip. Special sizes can be produced to customer requirements.
 
A self-lubricating bearing is a metallic component permeated in a lubricant oil. The oil provides a constant lubrication between bearing and shaft, so the system does not need any additional external lubricant. VIIPLUS Specialty Bearings features high performance, low wear self-lubricating bearing solutions.
 
METAL POLYMER COMPOSITE BEARINGS
Metal-polymer composite plain bearings enable economical solutions in many industrial and automotive applications. They are particularly effective with oscillating movements and achieve a rating life several times higher than that of bearings with conventional materials. In addition, all our new plain bearings are lead-free and, therefore, environmentally friendly.

PTFE Fabric Liners for Bearings
self-lubricating bearing materials are based on specially engineered liner fabrics with a tight woven fabric of synthetic fibers coated / saturated with a unique matrix of PTFE powder, high strength resin, and special fillers. This design provides high load rating, uniform wear behavior, low friction and extended service life.

CHARACTERISTICS


VSB-10 Self-Lubricating Multilayer Composite Bushing

  • 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.
 

STRUSTURE


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.
