Materials and Processes
Select the material grade and heat treatment for the operating conditions, processed material and equipment specifications. The options below are commonly used; confirm the final grade against the drawing and technical agreement.
Rubber
Select materials to suit OEM specifications and operating conditions; confirm the final grade and heat treatment against the drawing.
Polyurethane
Select materials to suit OEM specifications and operating conditions; confirm the final grade and heat treatment against the drawing.
Wear Characteristics and Replacement
Common wear modes and maintenance advice. The actual replacement interval depends on duty, material and operating data.
Common wear modes
- Material impact and sliding abrasion reduce surface thickness
- Localized impact causes dents and plastic deformation
- Prolonged wear exposes the base metal
- Wear around bolt fixing points causes the liner to loosen
Replacement criteria
Assess replacement against the remaining-thickness limits in the equipment manual and drawings. Stop the equipment for inspection and corrective action if through-cracks or fastening failures occur.
Material and Process Control
Materials, heat treatment, composite processes and inspection follow the specific drawing, duty and technical review.
Material Grade / Substrate
Rubber / Polyurethane
Heat Treatment Condition
Follow the applicable standard for the material grade; confirm heat treatment and hardness requirements against the drawing
Composite / Hardfacing Requirements
Follow OEM design requirements; confirm any hardfacing or composite construction against the drawing
Dimensions and Inspection
Inspect key dimensions against the drawing for the OEM model details. Check mounting and sealing surfaces individually and perform UT/MT non-destructive testing on castings.
Parts with the same name may not be interchangeable across models, drawing revisions, interfaces and materials. Confirm the full model, serial number and drawings before manufacture.
