Pom Composite Dry sliding bushing,Self-lubricating bearing thrust gasket composite washer wear - resistant plate basic introduction
A mixture of ethylene (PTFE) rolled into Pom Composite Dry sliding bushing plain bearings.It has the characteristics of small friction coefficient, good wear resistance, good corrosion resistance and no oil lubrication.Using this Pom Composite Dry sliding bushing can reduce the cost, reduce the mechanical volume, avoid the phenomenon of biting the shaft and reduce the mechanical noise and so on.
Pom Composite Dry sliding bushing Products have been widely used in the sliding parts of a variety of machinery, such as printing presses, elevators, textile machines, fitness equipment, hydraulic trucks, non-oil lubricated bearing, with steel plate as the substrate, intermediate sintered spherical bronze powder, surface rolling micromotor, solenoid valve, automobile, motorcycle and agricultural and forestry machinery.
1. Self-lube Layer POM 0.3-0.5mm. After rolling process completed, POM are filled in intersice of bronze layer, lubrication indents are stamped, which are full of oil grease, which will be removed and transferred on the mating surface, forms a physically lubricating film, which will reduced the firction coe. and protect the mating shaft.
2. Porous bronze layer; The layer provides bonded strength of
self-lub. Layer.
3. Steel Backing The layer provides load & thermal
conductivity.
4. Copper / Tin layer.
The dry sliding bushing indicates a range of sliding cylindrical bushings produced from a material with a composite structure. The support consists of carbon steel in which a porous bronze layer is sintered and then impregnated with co-acetal plastic. The polymeric surface has indentations in which the lubricating grease is located and protects the corresponding surface. The main Pom Composite Dry sliding bushing products of the dry sliding bushing line are cylindrical bushings (DIN 1494), as well as special parts made according to the customer's specifications.
The dry sliding bushing can be used in rotary and oscillating applications. Less maintenance required thanks to long relubrication intervals. Less wear, less sensitivity to on-board loads and no water absorption. Dry sliding bushing has good cushioning qualities and is shock resistant.

CHEMICAL PROPERTIES
The PTFE sliding layer is resistant to most chemical Pom Composite Dry sliding bushing products, and the corrosion resistance of the Pom Composite Dry sliding bushing depends on the steel base, which does not oxidize when:
• immersed in water, alcohols or glycols
• Available mineral and synthetic oils
• in acidic substances with pH> 5
• In alkaline substances with pH <9, Corrosion is initiated in
the case of repeated wet / dry cycles, the presence of oxygen and
when the temperature exceeds 90ºC.
The chemical resistance of the Pom Composite Dry sliding bushing is improved by tinning, but corrosion problems must be overcome with additional protection such as special tinning, Pom Composite Dry sliding bushing seals or the use of bronze-coated bearings or stainless steel. pillow block bearings .
FRICTION
The sliding layer of the dry sliding bushing ring has a PTFE
base which gives an excellent sliding quality due to the low
coefficient of friction.
The amount of friction cannot be defined exactly as it is
influenced by the following parameters:
• Load factor p x v at the surface
• Operating temperature
• Presence of liquids and lubricants
• Material and finish of the contact surface
The load factor p x v is the result of the specific load p (N / mm2) and speed v (m / s) and represents a reference parameter for checking the operation of this type of Pom Composite Dry sliding bushing. at p x v equal, the coefficient of friction decreases with increasing specific load, while the coefficient of friction increases with increasing speed.
| Sliding Speed v (m/s) | Specific Load p (N/mm2 ) | Coefficient of Friction μ |
| up to 0.001 | 140 | 0.03 |
| 0.001 to 0.005 | 140 to 62 | 0.04 to 0.07 |
| 0.005 to 0.05 | 62 to 11 | 0.07 to 0.1 |
| 0.05 to 0.5 | 11 to 1 | 0.1 to 0.15 |
| 0.5 to 2 | 1 | 0.15 to 0.20 |
Pom Composite Dry sliding bushing were developed for dry operation.
Nevertheless, the presence of clean liquids in the work area can
facilitate heat dissipation and extend the life of the bearing.
The presence of liquids, whether lubricants or others, can lead to
hydrodynamic operating conditions that allow a significant increase
in sliding speed with the same specific load.
The hydrodynamic operating conditions are influenced by the
following parameters:
• sliding speed
• Specific load
• Tolerance of the mating surfaces
• Viscosity of the liquid
• Operating temperatur
| Dry | Poor |
| Oil lubricated | Good |
| Grease lubricated | Very Good |
| Water lubricated | Poor |
| Process fluid lubricated | Poo |
Recommended for applications involving intermittent operation or peripheral lubrication.
·Automotive: joints, pin assemblies, propeller hinges, steering and other systems, rear chassis joints and hinges.
·Machine tools: spindles in drills, grinding and milling machines, and cylinder guide plates in multi-cylinder presses.
·Farm equipment: gearboxes, clutches, bale triggers and swivel wheels for bale accumulators, front axle pivot bearings, steering gearbox bearings and hitch pivot bearings for harvesters ...
The dry sliding bushing is particularly well suited for applications where the lubricant cannot be supplied continuously or repeatedly.
