Flange Double Acting Hydrauli Cylinder Large Bore Size for Chain Bulldozer Big bucket

Bulldozer hydraulic cylinders:

Hydraulic cylinder is the hydraulic actuator which could transfer the hydraulic energy into mechanical energy, do linear reciprocating motion (or swing motion). Use it to achieve reciprocating motion, eliminating the need for deceleration devices, and no transmission gap, smooth movement, and therefore in a variety of mechanical hydraulic system is widely used.

About piston rod: High strength damage resistant piston rod provides 100,000 PSI minimum yield material in 1" through 4 1/2" diameters. Larger diameters vary between 50,000 and 75,000 PSI minimum yield material. All rods are case hardened to 50-55 RC and hard chrome plated to provide maximum wear life. Stainless steel is also available. The hard chrome plated of the piston rod according to your requirement.

Piston Seals: Low friction, high load piston seals with outboard wear bands are standard. Loaded lip seals and cast iron rings are optional.

Quality control:

1. Seiko secret agents, to ensure quality of the piston rod.

2. The product have to go through heat treatment - bore boring - grinding - car processing - black nitriding and many other processes.

3. The company accepted the Valet processing various types and various sizes products, processing and processing more quotes, welcome to consult.
