Metal-Polymer Self-Lubricating Bearing Solutions | Hydraulic Components

Dryslide bushings

Dry slide bushings have a general structure consisting of a steel substrate connected to a porous bronze agglomeration layer impregnated and coated with a material from a PTFE / lead bearing. Dry sliding plain bearings take advantage of the excellent properties of a dry PTFE bearing and combine them with strength, stability and good wear resistance, excellent thermal conductivity and low thermal expansion.

WHAT IS PTFE BUSHINGS?

PTFE-bronze powder-steel is a widely used three-layer self-lubricating bearing material with good anti-friction and anti-wear.

APPLICATION
Given the performance characteristics in both dry and lubricated operating conditions, TOB-40 DP4 and DP4B bearing materials are extensively used in a wide range of automotive and industrial applications, such as:

Automotive
Braking systems, clutches, gearbox and transmissions, hinges - door bonnet and
boot, convertible roof tops, pedal systems, pumps - axial, radial, gear and vane, seat mechanisms, steering systems, struts and shock absorbers, wiper systems.

·Industrial

Aerospace, agricultural, construction equipment, food and beverage, marine, material handling, office equipment, packaging equipment, pneumatic and hydraulic cylinders, railroad and tramways, textile machinery, valves.

What is self-lubricating bearing
General profile steel-base oil-free self-lubricated bearing

1. oil-free or less lubricated, can be used without maintenance or less maintenance.

2. Good wear resistance, small friction coefficient and long service life.

3. with appropriate elastoplastic, the stress can be distributed on a wide contact surface to improve the bearing capacity.

4. The coefficient of static and dynamic friction is similar, so as to ensure the working accuracy of the machine.

5. Can make machinery reduce vibration, reduce noise, prevent pollution, improve working conditions.

6. Transfer film can be formed during operation to protect the grinding shaft.

7. The hardness requirement of grinding shaft is low, which reduces the processing difficulty of related parts.

8.Thin wall structure, light weight, can reduce the mechanical volume.

9. steel back can be plated with a variety of metals, can be used in corrosive media;At present, it has been widely used in sliding parts of various machines.

Boundary lubricated bearing series
1. Good load bearing and wear resistance.

2. Suitable for high load and low speed rotating motion, swing motion and often open and close frequently under load and not easy to form hydrodynamic lubrication occasions.

3. Under the condition of boundary lubrication, the bearing can be maintained without oil for a long time, while the bearing's service life can be prolonged by oil adding in the passing layer.

4. The plastic layer on the surface can leave a certain amount of margin during processing and forming, and the assembly can be processed by itself after being pressed into the seat hole to achieve better assembly size.

5. The products are mainly used in automobile chassis, metallurgical machinery, mining machinery, water conservancy machinery, construction machinery, agricultural machinery, steel rolling equipment, etc.
