Bushing & Bearings Services. Description: sliding bearings.
These are the wrapped cylindrical bushings ( DIN 1494 ). From a
technical point of view, the product is already widely known and
new applications are constantly being identified to take advantage
of the high load capacity, the self-lubricated feature and the
Applications include valves, commercial fire sprinkler systems,
mixers, blenders, swivels, and extruders.
All the valve's internal self-lubricating bearings are sliding
bearings, the whole material the use of carbon steel PTFE liner.
Because of its superior performance, the friction in friction
application fields become best material, such as sleeve bearing,
sliding bearing, the valve seat, seals, pump wear ring, etc.
Our bushings & bearing product range is covering many valve
types like: gate, globe, check, ball, butterfly, nuclear, subsea,
control, safety valve & wellhead equipment. All the indicated
valve bushings range is being operated within different industries.
The bushings majority is being used in the oil & gas, offshore,
chemical, power, nuclear, mining and air separation industry.
VIIPLUS is able to provide a complete solution of industrial valves
bushings with a fully traceable and in-house quality control
system. VIIPLUS proven stable quality, reliability and performance.
The valve mainly by the valve main body, the transmission system,
the hydraulic pressure stands, the electrically controlled box and
so on four parts is composed.
• High-impact strength
• High-resistance to wear
• High load-carrying capacity at low speeds
• Dimensionally stable
• Custom sizes for your application
• No lubrication required
• Low coefficient of friction

The PTFE non-corrosive,non-metallic bushing are strategically
located,providing maximum shaft
support, centralized alignment for a thru-shaft journal corrosion
and minimize bushing and frictional torque.

High Performance, Low Wear Solutions
SELF-LUBRICATING BEARINGS SOLUTIONS
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

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
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.
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.
