The Y-ring is designed as a static seal for the cylinder, which can replace the traditional O-ring/retaining ring combination. Through its unique design and material, the allowable extrusion gap can reach 0.4mm at a pressure of 500bar.

The piston seal is a two-way seal, used in conjunction with two piston guide rings, and has a two-way sealing effect.

Piston rod seal, double-lip design has better sealing effect, and polyacetal back-up ring is better under pressure.

The dustproof seal is a single-acting seal that is installed by extruding the outer diameter. It can effectively prevent dust and dirt from entering, and allow the residual oil to flow back.

Non-metal rollers refer to rollers made of non-metallic materials . Compared with traditional metal rollers, non-metal rollers have the advantages of flame retardancy, light weight, corrosion resistance, wear resistance, and low noise, so they have been widely used in modern industrial production.

There are a large number of flammable and explosive components such as gas dust in coal mines, and there are many metal equipment and instruments. When the equipment is moved and used, it is very likely to collide with the cable hook, which will produce sparks and lead to explosions.

The cable clamp for coal mining machine is made of stamped steel plate as the skeleton and high-density polyethylene through injection molding.
