WD-21 Dacro Bearing steel Spherical Washer ZPMC Port Machinery spare parts

ZPMC WD-21 Dacromet bearing steel ball washers are manufactured in strict accordance with original equipment manufacturer (OEM) standards, using high-quality bearing steel for precision cutting. Bearing steel possesses excellent load-bearing capacity, high hardness, and wear resistance. After professional heat treatment, its hardness and toughness are significantly enhanced, easily withstanding heavy loads and high-frequency operating conditions. It is not easily deformed or worn, perfectly matching the precise transmission requirements of bearings, effectively distributing bearing loads, reducing localized stress concentration, and extending the life of equipment connections. The product surface is treated with a professional Dacromet coating process, which involves dipping a zinc-aluminum sheet-based slurry into the coating and then sintering it at high temperature to form a uniform and dense protective layer. The film thickness is controlled at 6-12μm (single coating). It has the triple advantages of strong corrosion resistance, rust prevention, and wear resistance, with no risk of hydrogen embrittlement. It can effectively resist the corrosion of complex environments such as port humidity, salt spray, and dust. The salt spray test can reach more than 1000 hours (without red rust). It can also improve surface adhesion, ensuring a tight fit without loosening, and making installation convenient and efficient. It is suitable for various scenarios such as port equipment, heavy machinery transmission, and bearing matching. It is a high-quality matching accessory selected by ZPMC, which can directly meet the core needs of positioning, buffering, and sealing of various mechanical equipment, ensuring the stable operation of the equipment.
As a core component of ZPMC original equipment manufacturer (OEM), the WD-21 Dacromet bearing steel ball washer is specially designed for port equipment, heavy machinery transmission, bearing matching and other scenarios. Its core functions are to achieve precise positioning of bearings and equipment components, buffer and reduce pressure, assist in adjusting equipment installation deviations, compensate for shaft misalignment, reduce wear of bearings and related components, and improve the transmission stability of equipment. At the same time, it can reserve thermal expansion compensation clearance, adapt to various heavy-duty, high-frequency and complex working conditions, and take into account both structural stability and installation convenience.
