Advantages of high performance self - lubricating bearings
PTFE series self-lubricating bearings can meet the unique application requirements of the fluid power industry.We can provide complete solutions, reliable performance under high load and high speed, can resist cavitation and chemical corrosion, suitable for today's advanced fluid power applications, in gear pump, piston pump, vane pump, compressor, cylinder and other industries have a wide range of applications.
Maintenance-free bearings are used in common hydraulic fluid and many types of water emulsion conditions, suitable for vane pumps, gears, plunger pumps and motors.In addition to their excellent frictional and anti-wear properties, they are stable and reliable under required loads and speeds, making them suitable for many hydrodynamic applications.
Lubrication Free with Excellent Wear Resistance
High demand for reliability of application
We provide bearing solutions for hydraulic pumps and motors, including shaft bearings, half bearings, thrust blocks, wear plates, hydraulic cylinders, connecting rod bearings.Even with the most stringent application requirements, our customers can still rely on our high strength, scratch resistance and low friction aluminum alloy bearings.
· external gear pump and motor
· vane pump and centrifugal pump

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.
