2011238 2011239 CAT DRS 230 Pin & Retainer

2011238 / 2011239 Pin & Retainer is a matching part specially designed for CAT DRS 230 series chassis. It is not an original part but meets the original assembly standards. It is made of high-quality alloy steel, through precision processing and multiple surface treatment processes, it has excellent wear resistance, corrosion resistance and high strength, ensuring durability and safety.

2011238 / 2011239 Pin & Retainer is made through raw material inspection, forging, CNC precision machining, grinding and straightening, sandblasting pretreatment, phosphating + electrogalvanizing, cleaning and drying, full inspection and packaging.

1. Made of alloy steel, combined with precision heat treatment process, the hardness can reach HRC48-52.

2. The surface is treated with multi-layer galvanizing + phosphating to form a dense protective layer, which effectively resists erosion by sediment and corrosive media and greatly reduces the wear rate.

Precise tolerance control (0.005mm) can perfectly adapt to original accessories and greatly shorten maintenance downtime.

• Sandblasting and degreasing: removes scale and processing oil, providing a good adhesion basis for subsequent phosphating and plating.
• Chemical phosphating: forms a microcrystalline chemical phosphating film to improve adhesion and corrosion resistance.
• Electrogalvanizing: thick layer galvanizing on the basis of phosphating film, the coating is uniform and dense, and the anti-corrosion performance is significantly improved.
• Cleaning and drying: multiple drying and drying steps to ensure a clean surface without water marks.
