This steel graphite insert wear plate features a high-strength steel substrate with graphite plugs embedded in the sliding surface. The steel backing provides exceptional load capacity up to 200 N/mm² and dimensional stability under heavy loads. Graphite inserts deliver continuous maintenance-free lubrication, eliminating the need for external oil or grease. This wear plate is designed for guide and sliding applications where high loads and wear resistance are required. Custom dimensions, graphite patterns, and mounting hole configurations available for specific equipment requirements.
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.
