Product Description

 

Low Resistance Hydraulic Cylinder Parts Valve Bushing , Self Lubricating Bearings

 

Hydraulic cylinders you may not realize how many applications hydraulic cylinders bushings use.VIIPLUS supplier die mond bushings, which lead in range and inventory supply

 

Level move is realized by the co-operation of oil vat, handspike and synchronizer.

Hydraulic cylinder is the hydraulic energy into mechanical energy, do linear reciprocating movement (or swing movement) of the hydraulic actuator.

Cylinder sleeve bushings

A cylindrical metal part that guides the piston to and fro in a straight line within a cylinder.Air in the engine cylinder through the expansion of heat into mechanical energy;The gas is compressed by the piston in the compressor cylinder to increase pressure.

 

Bearing Design

Six factors related to bearing life:

(1) Load P
The greater the load, the shorter the bearing life; in any case, the maximum load must not exceed the theoretical maximum allowable load.

(2) Speed V
The higher the speed, the shorter the bearing life; in any case, the maximum sliding speed cannot exceed the theoretical maximum allowable value.

(3) PV Value
The working life of the bearing depends on the PV value, that is, the product of the actual load P and the sliding speed V. The smaller the PV value, the longer the bearing life.

(4) Temperature
The life of the bearing also depends on the temperature at which the bearing is used. The higher the temperature, the shorter the bearing life. Therefore, the heat dissipation characteristics of the relevant components should be considered in the design selection.

(5) Surface roughness of the grinding parts
When the wearer is made of alloy steel or hard chrome-plated shaft, the bearing life can be significantly improved when the surface roughness is Ra=0.4-0.63.

(6) Other factors
Other factors such as lubrication conditions.

 

 

Detailed Information​

 


Sf-1d hydraulic special bearing. Is on the basis of SF, 1 p combined with the oil cylinder and the working principle of the shock absorber and design a new type of material, under the condition of no oil is wear-resisting, in addition to the product has the advantages of SF, 1 d, especially suitable for reciprocating frequent occasions large lateral force. Its performance is similar to that of DP4, which is gradually replacing sf-1p products, which can be used in automotive, motorcycle shock absorbers and various hydraulic cylinders.

VSB-40 DP4 low friction bushings offer good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Very good performance in lubricated applications
· Good performance in greased applications
· Suitable for linear, oscillating and rotating movements
 
Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surfaces, suitable for rotating and oscillating movement, high chemical resistance, low absorption of water and swelling. The VSV-40 improved the friction and much good wear resistance over the common CSB-10 range under lubricated operation.

 

STRUSTURE

 

1. PTFE/Polymer fibres mixture thickness 0.01~0.03mm. Lead-free bearing layer provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE mixture.
3. Steel backing, provides high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.
5. Steel + Bronze Powder + PTFE/Fibre(DP4)
