Lubrication free bushings are used in applications where extreme agitation of parts and the force of friction to wear on parts. These self-lubricating bushings are able to withstand high temperatures and have high load-bearing tolerances.

Our self-lubricating bronze bearings feature precision tolerances, proprietary internal geometries and quality materials. Our self-lubricating bronze bushings have strong performance, consistently and reliably.

High Quality Gear Pump Bushing Metal Polymer Composite Bearing PTFE Bronze Steel Bush

Self-lubricating Bronze Sliding Bushing PTFE Material Structure

1. 0.01 ~ 0.03mm PTFE / Pb blend provides an excellent initial transfer layer that effectively covers the mating surface of the sleeve assembly to form a solid oxide type lubricant film.
2. 0.20-0.35mm sintered bronze powder, provides max. the thermal conductivity away from the sleeve surface also serves as a reservoir for the PTFE-lead mixture.
3. The bronze backing provides extremely high load-bearing capacity, excellent heat dissipation. They have very good corrosion resistance.

Steel Backed Ptfe Lined Bushings

• Classification of cylinder guide sleeve bushing working principle

1.According to the classification of structural characteristics, cylinders bushing are mainly divided into piston cylinder bushings and diaphragm cylinder bushings;

2.According to the form of motion, it is divided into two categories: linear motion cylinder bushings and swing cylinder bushing.

• Cylinder guide sleeve bushing working principle and cylinder bushings construction

• 1, 3- buffer plunger 2- piston 4- cylinder 5- guide sleeve 6- dust ring 7- front end cover 8- air port 9- sensor 10- piston rod 11- wear ring 12- sealing ring 13- rear end cover 14- buffer throttle valve.

• When the compressed air is input from the rod-less cavity, there is a rod-cavity exhaust, the pressure difference between the two Chambers of the cylinder acting on the piston force formed by the piston movement, so that the piston rod extends;

• When there is rod-cavity air intake, no rod-cavity exhaust, make the piston rod retraction, if there are rod-cavity and rod-cavity alternate air intake and exhaust, the piston to achieve reciprocating linear motion.

A guide sleeve bushings 5 is arranged on the end cover of the rod side to improve the guiding accuracy of the cylinder.

It can substitute a conventional bearing where saving space is desired.

Steel Backed Bushing provides superior shock and impact load resistance.

The Steel Backed PTFE Lined bushing maintains a low coefficient of friction and is usable without lubrication at high load, low speed operations with excellent wear resistance.
