Application


Self-lubricating bearings are typically used in high load applications, including valves, hydro power equipment, lifting equipment, hydraulic pumps, and have a long proven history of providing outstanding performance in extreme applications from Ariane rockets to deep sea valves.

Boundary Lubricating Bushings Sleeve Bushes


PTFE Fiberglass Lined Stainless Steel Bushings

VIIPLUS Self-Lubricating Bearings Material provides high-end casting to our valve divisions including materials like (low temperature) carbon steel/ stainless steel/ PTFE Bushing POM Bushes and high bronze alloy


steels bearings. All analyses regarding the mold and pattern designs are being performed in our own premises in order to guarantee a constant casting level and quality.


The Structural Characteristics


VIIPLUS metal composite self-lubricating materials for high-quality low carbon steel substrate, sintering porous spherical copper powder layer, the surface of copper is given priority to with PTFE wear-resistant lubricating materials as bearing layer, the material has the excellent mechanical bearing capacity, the middle copper powder layer can not only transfer the heat generated by the bearing during operation in time but also increased the strength of the combination of the plastic layer and substrate.PTFE is designed for complete dry friction and a variety of materials are developed for lubrication, friction coefficient, and durability.VIIPLUS's PTFE metal composite delivers the best performance over the widest range of loads, speeds, and temperatures with or without external lubrication.


The product application


Agricultural machinery: tractors, combine harvesters, crop sprayers, bulldozers, grader, etc.
Automobile industry: power steering pump, steering gear thrust gasket, disc brake, shock absorber, door hinge, wiper, chair horn, air valve, and solenoid valve;
Office and business machines: copier, fax machine, printer, mail processor, etc.
Hydraulic components and valves: gear pump, plunger pump, vane pump, ball valve, butterfly valve, cylinder, cylinder, and other hydraulic components;
Home appliances: refrigerators, air conditioners, vacuum cleaners, sewing machines, cleaning machines, microwave ovens, and fitness equipment, etc.
And other logistics machinery, packaging machinery, textile machinery, port machinery, mining machinery, and forest machinery, and so on.
In actual use, according to the different environment, working conditions and environmental protection requirements, low-carbon steel plate can be changed into a copper plate or stainless steel plate, the inner surface of the plastic layer can choose PTFE lead or lead-free materials and other polymer filler, the appearance can be tin or copper plating.

Du Sf-1 Boccole Bushes & Bushes | Viiplus Bearing Stainless Steel Bushing With PTFE


Description


VIIPLUS bushes are produced in a lightweight, compact material with minimum bulk, simplifying shaft assembly. Featuring high-level chemical resistance, shafts can be covered or plated with materials resistant against chemically aggressive liquids, gas or solids, through the application of an additional galvanic layer. This type of bush does not require lubrication and its operating temperature is between -195°C and +280°C.

Rolled Dry Sliding Bearings (PTFE)
Steel + Bronze Powder + PTFE/Fibre(DU)


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

  • As they do not absorb oil and water, bushes have a low expansion and high conductivity rate, as well as good thermal stability. Furthermore, by using this type of bush, vibrations, noise, and pollution are significantly reduced.

Material is designed to operate without supplemental lubrication and will perform excellently 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 the rotary, linear, and oscillating motion.


Structure


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.
