Frequently Asked Questions

Steel offers significantly higher load capacity and better dimensional stability than bronze. Steel wear plates are ideal for heavy-duty applications where high loads and impact resistance are required.

Graphite inserts are mechanically retained in precision-machined pockets within the steel surface. The inserts are pressed in securely, ensuring retention during operation.

Yes. Mounting holes can be machined into the wear plate at specified locations. Counterbored, threaded, or through holes available based on application requirements.

Hardened steel with surface hardness of 50-60 HRC and surface finish Ra 0.4-0.8 micrometers. This provides optimal wear life and lubrication film formation.

Replace when surface wear exceeds 0.5mm, when graphite on the sliding surface falls below 12% of original coverage, or when the plate shows signs of deformation or cracking.
