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.

PTFE Metal-Polymer Marginal-Lubricating Bearings

Viiplus PTFE Metal-polymer marginal-lubricating bearings maintenance-free steel backing series

 

A PTFE Metal-polymer marginal-lubricating bearings is comprised of a metal shell and a very thin polymer coating (PTFE) applied to the inside.

 

Choose from our selection of PTFE Metal-polymer marginal-lubricating bearings in a wide range of styles and sizes. In stock and ready to ship.

Consisting of a metal backing for high mechanical strength and a sintered bronze layer, Metal-Polymer bearings are impregnated with an anti-friction overlay enriched with PTFE or high performing thermoplastic combined with fillers to obtain an optimal running surface.

Features Of  Metal-Polymer Composite Bearings

 

It is suitable for boundary lubricating applications. It is recommended to lubricate the components with grease before assembling. The oil deposit can hold the lubricant with optimized matrix and to hold possible incoming containments during the operation. Lubricating during the operation helps to prolong the bearing duration. The wideoperation temperature range of -150°C-+250°C and the reliable chemical resistance of the bearing ensure suitable applications under middle to high load conditions. CSB-80M is a material with PEEK/PTFE thickness of 0.1-0.2mm without oil deposits on the surface, it is a machinable material after assembling.
 

1. Strength and Stiffness and Low Friction

When a steel backing is combined with PTFE or POM, the strength and stiffness properties are enhanced by the low friction of the polymer material. The use of a polymer layer such as PTFE also deals with issues such as corrosion and unwanted chemical interactions by providing protection the metallic layer(s).

 

2. Many composite bearings are, by their very nature, dry-running.

They can be designed so that no grease or lubricant is required, which can be very important for applicants that are sensitive to contamination or other instances where grease could pose a problem. When designed correctly composite bearings can provide extreme low friction, almost eliminate issues with stick-slip, and reduced break-away torque requirements.

 

3. Dimenstional Stability

Another issue that composite bearings can address quite well is dimensional stability.Some polymers are especially susceptible to dimensional changes through absorption of water or reactions to temperature variations. The use of composites can significantly reduce those problems.

PTFE Metal-polymer marginal-lubricating bearings

Structure:

 

1. PEEK/PTFE thickness 0.20~0.35 mm, provides good wear resistance. This bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.

2. Sintered bronze thickness 0.20-0.35mm, provides strong mechanical bond and excellent thermal conductivity.

3. Low-carbon steel, provides mechanical strength and thermal conductivity.

Composite Options for Bushings and Bearings

 

When it comes time to select a bushing or bearing for a particularly sensitive application, it might be wise to add composites to your list of potential bearing materials. Composite bearings may be primarily metal with a low-friction polymer lining, or they may be filament wound fiber reinforced materials with a polymer matrix. Regardless of which type of composite bearing is under consideration, remember that they can offer added benefits such as improved strength, stiffness, wear properties, and reduced friction while possibly eliminating the need for lubricants.

 

Typical Applications

 

The material has wide operation temperature range and can be used under high PV value condition. It is used in hydraulic motors, pumps, diesel engine common rail system and heavy truck brake systems.
