KSEW Wear Plate

I. Product Overview

The Graphite-Plugged Bronze Wear Plate is a premium, maintenance-free sliding element designed for linear, oscillating, and intermittent motion applications. It consists of a high-strength bronze matrix with embedded solid graphite lubricant plugs distributed across the working surface in a precise grid pattern.

The graphite plugs provide continuous solid-film lubrication throughout the bearing's service life, eliminating the need for oil, grease, or external lubrication systems. This makes the wear plate ideal for applications where conventional lubrication is impractical, undesirable, or impossible - such as high-temperature environments, cleanrooms, food-grade machinery, or hard-to-access locations.

The plate features counterbored mounting holes at each corner for flush mounting with socket-head cap screws, ensuring secure fixation without interfering with the sliding surface.

V. FAQ

Q1: Graphite-plugged bronze vs. oil-impregnated sintered bronze?

Graphite-plugged bronze uses solid graphite plugs in a cast bronze matrix - higher load (up to 250 N/mm²), wider temperature range (-40 to +350°C), truly maintenance-free. Sintered bronze is oil-impregnated porous bronze - lower load (<50 N/mm²), limited temperature (~120°C), eventually runs dry.

Q2: Can the graphite pattern and size be customized?

Yes. We customize plug diameter (6-10mm), spacing, coverage ratio (20-35%), lubricant type (graphite/PTFE/MoS2), and shape. Standard sizes: 30×30mm to 500×500mm, thickness 5-50mm. Custom dimensions per your drawings.

 Q3: MOQ and lead time?

- MOQ: Standard sizes 10 pcs, custom sizes 5 pcs, samples 1-2 pcs accepted
- Lead time: 3-7 days (stock), 10-15 days (existing tooling), 20-30 days (new tooling)

Q4: Do you provide material certificates?

Yes - chemical composition, mechanical properties, dimensional inspection,  certificate upon request.

Q5: Can you manufacture equivalents for Oilesxx, GxB, or Dxva Glide?

Yes. We can match Oiles 500SP/500F, GxB GRAPHALLOY, Dxva Glide, and KS Permaglide. Provide the competitor's part number and we will match dimensions and graphite arrangement.
