Rod guidance for pneumatic and hydraulic cylinders, These Bush Bearings are widely used in the Machinery Industry. (Inside Diameter x Outside Diameter x Length).
Stainless steel corrosion resistant bearings, stainless steel as a matrix, the middle of the sintering corrosion resistant alloy powder, the surface of the rolling ptfe based low friction materials, after the rolling molding of a very effective corrosion resistant materials.It has the characteristics of oil resistance, acid resistance, alkali resistance, seawater resistance and wear resistance. The PTFE material on the surface does not contain lead.
In food and beverage machinery, chemical medium ph flow of the pump valve, pharmaceutical machinery, printing and dyeing machinery, chemical machinery, Marine industry corrosion resistance sliding parts are most suitable for use.
Our metal-backed PTFE (polytetrafluoroethylene) -based metal bushing materials have a common structure consisting of a steel beam connected to a porous bronze sintered layer. This bronze sintered layer is impregnated and covered with the filled PTFE socket lining. The steel beam provides mechanical strength, while the bronze sintered layer creates a strong mechanical bond between the beam and the socket liner. This construction promotes dimensional stability and improves thermal conductivity. These PTFE linings offer exceptionally low friction.
1. The PTFE / Pb mixture 0.01 ~ 0.03 mm as a sliding layer,
provides an excellent initial transfer film, which effectively
coats the contact surface of the bearing assembly, forming a
homogeneous oxide solid lubricant film .
2. Porous bronze 0.2 ~ 0.3 mm, provides max. the thermal
conductivity away from the bearing surface, also serves as a
reservoir for the lead-PTFE mixture.
3. The base of 0.7 ~ 2.3mm mild steel provides fundamental
structural support and provides exceptional load-bearing capacity
and excellent heat dissipation.
4. Tinning 0.005mm or copper plating 0.008mm provides good
corrosion resistance.

· Good wear and friction performance over a wide range of oil-free
loads, speeds and temperature
· Also work well with lubrication
· Maintenance free, long life
Metric FTH Series Flanged Dryslide PTFE Bushing Same type It is a polymer made of tetrafluoroethylene as monomer.White waxy, translucent, good heat and cold resistance, can be used in -180 ~ 260 C for a long time.This material has the characteristics of anti - acid, anti - alkali, anti - various organic solvents, almost insoluble in all solvents.At the same time, ptfe has the characteristics of high temperature resistance, its coefficient of friction is very low, so it can be used for lubrication, but also become easy to clean the ideal coating of the inner layer of the water pipe;Toxic, human carcinogen.
