Drawing Revision
Confirm dimensions by measuring the sample or using the customer drawing. Cross-check the drawing revision against the model on the equipment nameplate.
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.
Pearlitic Chromium-Molybdenum Steel
Select materials to suit OEM specifications and operating conditions; confirm the final grade and heat treatment against the drawing.
High-hardness white iron; laminated plate and rubber composite construction is also an option.

Wear and Replacement Criteria
Common wear patterns and maintenance guidance are outlined below. Determine replacement intervals from operating conditions, processed material and equipment performance data.
Common Wear Patterns
- Material impact causes surface wear and deformation
- Sliding material causes grooving wear
- Localized impact causes dents
- Wear affects equipment operating efficiency
Replacement Criteria
Assess replacement against the remaining-thickness limits in the equipment manual and drawings. Inspect and take corrective action if through-cracks occur or equipment performance is affected.
Materials and Processes
Materials, heat treatment, composite construction and inspection requirements depend on the specific drawing, operating conditions and technical review.
Material Grade / Substrate
Pearlitic chromium-molybdenum steel or high-hardness white cast iron; a laminated plate and rubber composite structure is another option.
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 part number. Check mounting and sealing surfaces individually and perform UT/MT non-destructive testing on castings.
Parts with the same name may not be interchangeable because of differences in machine model, drawing revision, mounting interface or material specification. Use the complete model, serial number, drawing number and drawing before manufacture.
