Tie rod

Benefits of Tie Rod cylinders include the ease of disassembly for repair due to no welding being required in the design.

Motus’ tie rod cylinders are made to SAE standards for interchangability and these cylinders are a great low-medium cost option for applications where cylinders operate with pressures 3500PSI and lower.

Common applications

  • Transportation
  • Agriculture

Tie-rod SAE design

Tie Rod Range – up to 3500psi

Motus Tie Rod double-acting cylinders are manufactured to SAE standards for OEM and replacement parts to a wide variety of applications. They are available from 2” to 5” bore sizes with strokes up to 36”.

They contain some subtle improvements from the regular sources, including the 3500psi operating pressure rating, ORB ports as standard and custom colours for OEM supply.

Barrel

Precision honed high-tensile tubing for maximum seal life.

Head / gland

Close grained, ductile cast iron giving maximum bearing surface in minimum length

Shaft

Cylindrically ground and polished chrome bar Available in 1045 hard chrome bar and 4140 grade high tensile bar for increased strength and damage resistance in harsh environments.

Clevis ends

Ductile Iron clevises to SAE standards, supplied with zinc plated pins and clips Larger diameter pins, case-hardened and austemped castings for improved wearing ability.

Ports

Internally ported to ORB (SAE) standards, including 2 ports in the base at both inline, and 90-degree positions for versatile mounting options.

Piston

Close grained ductile cast iron, giving maximum bearing surface.

Tension rods

Nickel-chrome rods for superior corrosion resistance.

Seals

Premium North American seals utilised throughout. Polyurethane twin lip design rod seal for long service life. Tough metal backed mud and ice wiper (option of polyester snap-in). O-Ring and contoured face backups on tube connections. Durable polyester cap seal has excellent load holding and wear resistance properties.
