    “Valve Bushings perfect,Thank you so much for your superior customer service! The steel-backed, PTFE lined rolled bushings are a low cost, a general-purpose product that provides excellent wear characteristics at high loads and speeds over a wide temperature range. They are designed to be self-lubricating and maintenance-free.
    Michael Russo
    The wrapped bronze bushings is produced with diamond-shaped lubrication indents on the inner diameter surface which provide lubricant reservoirs that allow for prolonged service.

Product Description

The self-lubricating multilayer composite bushing is a high-performance wear-resistant component that combines the advantages of various materials. Constructed primarily from carbon steel, it incorporates copper powder and (Polytetrafluoroethylene) filler to enhance its lubricating properties and overall durability.

The carbon steel base provides the bushing with exceptional strength and rigidity, ensuring it can withstand heavy loads and demanding operating conditions. The copper powder, on the other hand, acts as a natural lubricant, reducing friction and wear between moving parts. This not only prolongs the lifespan of the bushing but also contributes to smooth and efficient operation.

The filler further enhances the lubricating capabilities of the bushing. is known for its excellent chemical resistance, non-stick properties, and low friction coefficient. By incorporating into the composite material, the bushing achieves even smoother operation and reduced wear over time.

The multilayer design of the composite bushing allows for optimal distribution of materials, ensuring even wear and consistent performance throughout its lifespan. This design also provides flexibility in terms of material selection, allowing for customization to meet specific application requirements.

In summary, the self-lubricating multilayer composite bushing, with its carbon steel base, copper powder, and filler, offers a robust and reliable solution for applications requiring high wear resistance and smooth operation. Its superior lubricating properties and durability make it an ideal choice for a wide range of industrial applications.

Carbon-based lead-free lubricating bearings Cylindrical Sleeve Bushes | VSB-10


VIIPLUS VSB-10 is backed with copper-plated steel with porous bronze sintered on the steel and polymes (+Pb) imbedded into the bores of the bronze. By combining the metals and the polymers tog, its products are endowed with the lower friction coefficient and good capacity of anti-abrasion and self-lubrication. Moreover, the steel back is plated with a erosion-prevention layer. Products of VSB-10 series are widely applied in printing, weaving and tobacco producing machines, gymnastic equipments, etc.



Carbon-based lead-free lubricating bearings Cylindrical Sleeve Bushes have same features as the VSB-10, but without lead.


Typical application


Typicai applicaton
Application: the printing, woven, tobacco and gymnastic machinery, etc.
same application as the normal VSB-10, but much more for automotive industry, food industry, medicines, drink machines and so on which not allowed to use the lead and difficulty forming the oil film or need lubrication parts.
