When it comes to dry sliding bushings, having a butt joint flange design with PTFE (Polytetrafluoroethylene) bushes can offer exceptional performance in various applications. This combination provides both durability and lubricity, making it a reliable choice for demanding environments.
The butt joint flange design allows for easy installation and secure attachment of the bushing to the application. The flange provides a larger surface area for attachment, ensuring that the bushing remains firmly in place during operation. This design also helps to distribute the load evenly across the bushing, reducing wear and tear.
The PTFE bushes within the bushing are responsible for providing lubricity and reducing friction. PTFE is known for its low coefficient of friction and excellent wear resistance, making it an ideal material for dry sliding applications. The bushes are precisely fitted into the bushing, ensuring a smooth and reliable operation.
The combination of the butt joint flange design and PTFE bushes results in a bushing that can handle high loads and temperatures while maintaining a low coefficient of friction. This makes it suitable for applications such as industrial machinery, automotive components, and aerospace equipment.
The dry sliding bushing can be customized to fit the specific requirements of your application. We can adjust the flange size, bush material, and other specifications to ensure that the bushing meets your exact needs. This allows us to provide a solution that is tailored specifically to your application, ensuring optimal performance and longevity.
In conclusion, a dry sliding bushing with a butt joint flange design and PTFE bushes offers exceptional performance in demanding applications. The combination of the flange design and PTFE bushes provides durability, lubricity, and reliability, making it a reliable choice for your specific needs.

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
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.
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 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.
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 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.
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)
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.
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.
