Customer Reviews
Our company import the bronze gleitlager from viiplus china,viiplus professional team makes sure customs clearance is always smooth. They provide an accurate bronze bushing classification, handle all the paperwork,We have received the self-lubricating bronze bushings. They look well done and the high quality.

—— David from Canada

We import the bronze gleitlager from China to under the incoterm FOB shanghai, sometimes by Air. viiplus is a very good bronze gleitlager supplier, they are very professional and patient, after we inform the new order, they will manufacturer bronze gleitlager in time and give us the schedule , and then we just need to receive the bronze parts

—— Valerie from California

The best surface finishes for Sleeve Bearing, tighter concentricity, and bronze bushings material uniformity. The good supplier of standard inch and metric sleeve bearings and bushings from china.

—— Daisy From Germany

“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.

—— Beverly from Florida

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.

Latest company case about Hydraulic components Bearing sleeve

 

Hydraulic systems are suitable for hydraulic systems mainly because of their system disassembly difficulties and maintenance-free requirements which are important for their system characteristics.

 

High seal, friction resistant bearing sleeve


 It is a new kind of material designed on the basis of vsb-1p Hydraulic bearing combined with the working principle of oil cylinder and shock absorber. It is more wear-resisting under the condition of no oil. In addition to the advantages of vsb-1p, the product is especially suitable for the occasion of reciprocating frequent large trend force.Its performance is similar to that of foreign DP4. At present, this product gradually replaces vsb-1p product, which is suitable for automobile, motorcycle shock absorber and various hydraulic cylinders and other fields.

 

Bearing application

 


  Hydraulic components and valves: gear pumps, plunger pumps, vane pumps, ball valves, butterfly valves, cylinders, cylinders and other hydraulic components;

 

Chemical properties
The surface polymer of VSB-2 Hydraulic bearing sleeve is resistant to chemical corrosion, so its corrosion resistance mainly depends on the steel back and

exterior electrodeposit.Copper or tin plating on steel back surface can effectively prevent atmospheric corrosion;If working in corrosive medium, steel back can be galvanized, etc.

 

 

 

 

 

 

The main factors affecting the bearing sleeve life
1) the influence of PV value, which is an effective indicator to determine

the wear life of chb-1.If life extension is required, the PV value must be reduced.
2) the influence of ambient temperature. The higher the ambient temperature, the

shorter the service life of chb-1.3) the impact of dual parts
The service life of chb-1 bearing can be significantly improved when the dual part

adopts alloy steel or hard chromium plated shaft, and the surface roughness

Ra=0.4~0.63 range.In addition to the standard products shown in the catalog

non-standard products can be provided or ordered upon customer request.

 

Operating characteristics of hydraulic bearing


 

 

Phase 1 the surface layer PTFE mixture is transferred to the dual surface to fill the pits in the dual surface and form the transfer film.
Phase 2 After running, the friction becomes the friction between PTFE, the friction coefficient is low and stable, and the wear rate of the material is low and stable
Phase 3 The consumption of PTFE lubricant in the pores of the porous layer makes it impossible to obtain enough lubricant between the friction interfaces.With poor lubrication between friction surfaces, the friction coefficient rises rapidly, and the wear rate of the material accelerates rapidly, until 70% of the bronze is exposed, the hydraulic bearing life is close to the end.
