Wear plates are precision-ground components that provide sliding surfaces and reduce friction between moving parts in bolster assemblies.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Hardness | 58-62 HRC | |
| Thickness | 10-50 mm | |
| Surface Finish | Ra 0.4-0.8 μm | |
| Thermal Stability | Maintains dimensional accuracy up to 200°C | |
| Flatness Tolerance | 0.02 mm/m |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
A structural component in a rail chassis that connects the truck frame to the car body through the center plate and side bearings.

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
3 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Replacement intervals depend on operating conditions, typically 6-24 months. Monitor for visible scoring, thickness reduction beyond 20%, or increased clearance beyond tolerance.
Limited resurfacing is possible if sufficient material remains and hardness hasn't degraded, but replacement is generally recommended for optimal performance.
