Our Products
We offer a wide range of Guide stripes and to fit any application. Available in NYLON, PTFE and composite materials. Standard as well as tight tolerance wear rings are available in a variety of heights, thicknesses and cut (bulk strip, cut-to-length and machined rings are also available in a variety of heights and thicknesses.)
The wear strip can be cut to any length and used as a wear ring for a hydraulic or pneumatic piston. Available in low friction Bronze filled PTFE strip or Polyester Resin /Nylon material.
Wiper seals are typically used in conjunction with other sealing elements. A wiper seals primary function is to provide a physical barrier to limit the ingress of moisture, dirt and other contaminants into the primary sealing system, preventing damage to hardware and seals.
Wiper seals require a snap in fit into a rod groove locations and compliment a primary sealing solution.
A single-acting piston seal is designed for cylinders where pressure is applied from one side only. The piston in single-acting cylinders may have oil on the pressure side only, while the opposite side is open to atmosphere. Therefore, the piston seal must leave a minimum of oil film when passing along the cylinder bore since thetransportationof oil otherwise would result in a leakage to the exterior.
In single-acting cylinders, the open end may push air out and draw air in as the piston reciprocates. This air may carry moisture and contaminants into the cylinder, which can lead to seal damage. Vent filters may be fitted to the open side of the cylinder to reduce contaminants entering the inside of the cylinder. The cylinder bore may be hard chromium plated to prevent corrosion.
Piston seals are maintain sealing contact between the piston and the cylinder bore. Differential pressures acting on the piston to extend or retract the piston rod can be in excess of 400 bar(5 800 psi). The pressure acting on the piston seal increases contact forces between the piston seal and cylinder surface. Therefore, the surface properties of the sealing surfaces are critical to proper seal performance.
Double-acting cylinders are the most widely used cylinder types. They operate withpressureon both sides and, therefore, require double-acting seal arrangements.
Double-acting piston seals have a symmetrical profile (cross section) and identical sealing functions in both directions.
Typically, double-acting piston seals consist of a slide ring and an energizer and an anti-extrusion ring. The deformation of the elastomeric energizer when installed provides adequate force to keep the slide ring in dynamic sealing contact with the cylinder bore, while sealing statically against the seal housing groove.
A double-acting cylinder typically has the same fluid on both sides of the piston. Therefore, a relatively thick lubrication film can be permitted between the piston seal and the cylinder bore to minimize friction and wear. The transportation of fluid occurring during dynamic operation is, however, small and insignificant in most applications.
