Guidance and bearing support

Keep the piston and rod running in alignment

Auter WST WEAR STRIP is a fabric reinforced polyester resin bearing strip for hydraulic cylinder guidance. Installed in the piston or rod guide groove, it supports lateral loads, helps maintain alignment and separates moving metal surfaces. By limiting direct contact between the piston and bore or the rod and gland, WST helps reduce scoring and wear while supporting the operation of the sealing system. The reinforced resin construction combines a wear-resistant bearing surface with structural support for demanding cylinder service. Strip thickness, bearing width and installed clearance are selected together to suit the load and available groove space.

Carry lateral loads

Provide bearing support at the piston or rod guide location, with bearing width selected for the application load.

Separate metal surfaces

Help prevent direct contact between piston and bore or rod and gland, reducing the risk of scoring and wear.

Support cylinder alignment

Work with the cylinder bearing arrangement to guide reciprocating movement and support the sealing system.

Material construction

Fabric reinforced polyester resin

WST is made from fabric reinforced polyester resin. Review the material against the fluid, temperature and bearing load of the application.

  • Fabric Reinforced Polyester Resin — the specified material for Auter WST WEAR STRIP
  • Fabric reinforcement provides structural support within the polyester resin bearing material
  • Confirm compatibility with the actual hydraulic fluid, additives and operating temperature when selecting the strip

Dimensions before part matching

Specify the strip and its groove together

Send a section drawing when possible. Strip thickness, bearing width, cut length and installed clearance need to match the cylinder hardware.

Application review

Select WST for the load and available bearing space

The bearing arrangement and cylinder geometry determine how lateral loads reach the guide strip. Review these inputs before confirming the strip dimensions.

  1. Provide piston or rod diameter, groove diameter, groove width and strip thickness
  2. State the required strip width, cut length or finished bearing diameter, end-gap requirement and quantity
  3. Include the expected side load, bearing arrangement and available bearing length
  4. Specify reciprocating speed, stroke, duty cycle and operating temperature
  5. Identify the hydraulic fluid and the condition of the mating metal surfaces
  6. For a Hallite 506 replacement inquiry, send the existing part reference or drawing so dimensions, clearance and application requirements can be checked

WST FAQ

Questions about WST wear strip

What is WST wear strip made from?

Auter WST WEAR STRIP is made from fabric reinforced polyester resin. The exact fluid, operating temperature and bearing duty should be reviewed when selecting it.

Can WST be used for both piston and rod guidance?

WST is used for hydraulic cylinder piston or rod guidance where the groove, strip dimensions, bearing arrangement and operating conditions are suitable. Send a drawing showing the intended location.

Does WST seal hydraulic pressure?

WST is a bearing and guide element. It supports lateral loads and helps separate moving metal surfaces; pressure sealing requires the appropriate piston or rod seals.

How do I specify the correct size?

Provide piston or rod diameter, groove diameter and width, strip thickness, bearing width, and cut length or finished bearing diameter. Include the required end gap and drawing tolerances.

Can I request a replacement for Hallite 506?

Send the existing part reference, dimensions or drawing and the operating conditions for review. A reference alone does not confirm interchangeability or application suitability.

What operating limits should I use?

Ask for confirmation against the proposed strip and actual application. Side load, bearing area, speed, temperature, fluid and hardware clearances must be assessed together; this page does not assign a universal operating rating.

WST technical inquiry

Send your groove drawing or wear-strip dimensions.

Tell us whether the strip guides the piston or rod, then include dimensions, side load, fluid, temperature and quantity.

  • Strip thickness, width and cut length
  • Piston or rod diameter and complete groove dimensions
  • Load, speed, stroke and duty cycle
  • Existing part reference, drawing or sample details

Available dimensions, supply format and application suitability are confirmed during quotation.
