| Design features and benefits | |||
| Piston rods | Cushioning | Barrel | |
| Made from medium carbon Steel. Precision ground, hard chrome- plated and polished to ensure smooth, dent & rust resistant surface for best sealing and long life.; | Self-aligning cushioning bush ensures alignment of the rod movement inside the cushioning chamber, providing accurate damping action at the end of stroke. | Made from cold drawn seamless Steel tubes. Honed to 0.4 micron and higher surface finish to minimize internal friction and longer seal life and performance. | |
| Cover plates | Piston seal | Piston rod gland | |
| Fine machined from Steel and constructed with a sturdy design to withstand high pressure loads. | Provided with low friction single piston seal design for no stick-slip effect in rotated two wear strips. This design provides smooth operation, long bearing life and high load carrying capacity. | Made from Turcite T47 material. Non-metallic wear rings are used in the cylinder head for precisely guiding the piston rod of the working cylinder and absorbing lateral forces which occur. At the same time, metallic contact between the sliding parts of the cylinder, e.g. piston rod and cylinder head must be prevented. Nonmetallic wear rings offer major benefits compared to metallic guides. | |
| Rod seal | Tie rods | Wiper seal | |
| Polyurethane U-cup seal is used which has double lip design for good sealing effect & maximum flexibility. | Made from high tensile Steel rods tightened with hexagonal nuts for easy maintenance. | The wiper is a double working nitrile wiper seal. The wiper lips are designed to wipe off dust and provide light sealing. It has advantage of radial tension to wipe off particles, dust and water. | |
