Heavy Duty Press Roller Brass Bearings

Our Heavy Duty Press Roller Brass Bearings use high-strength brass (ZCuZn25Al6Fe3Mn3) as the base material, adding elements such as aluminum, iron, and manganese to form a hard phase. Combined with embedded graphite or MoS₂ solid lubricant, this creates a dual protective structure of "wear resistance + self-lubrication." The product boasts a tensile strength ≥725MPa and a hardness of HB210–270, easily withstanding high static and impact loads during equipment operation. Its coefficient of friction is as low as 0.12~0.16 under dry friction, forming a stable lubricating film even in oil-free or low-oil environments, perfectly suited for pressure rollers where continuous lubrication is difficult.

Regarding temperature adaptability, Heavy Duty Press Roller Brass Bearings can operate stably for extended periods within a temperature range of -40℃ to 250℃, with short-term temperature resistance up to 300℃, fully meeting the requirements for high-temperature applications. The protective oxide layer formed by aluminum and manganese provides excellent corrosion resistance in humid, dusty industrial atmospheres (not suitable for seawater or strong acid/alkali environments). Compared to tin bronze or aluminum bronze, Heavy Duty Press Roller Brass Bearings reduces raw material costs by 20%~30% while maintaining excellent machinability, achieving a balance between performance and cost.

Lubrication has always been a challenging problem for users in forging presses where continuous lubrication is difficult. Our Heavy Duty Press Roller Brass Bearings achieve self-lubrication by cleverly embedding solid lubricants such as graphite or MoS₂. Even under oil-free or low-oil conditions, they can form a stable lubricating film, effectively reducing the coefficient of friction (μ=0.12~0.16 under dry friction), minimizing wear, and extending service life. This innovative design not only simplifies the maintenance process and reduces maintenance costs but also improves the reliability and stability of the equipment, freeing users from worries about lubrication issues.

Heavy Duty Press Roller Brass Bearings not only possess excellent mechanical properties but also exhibit good high-temperature and corrosion resistance. They can operate stably for extended periods within a temperature range of -40℃ to +250℃, with short-term temperature resistance even reaching 300℃, meeting the requirements of equipment such as forging presses in high-temperature environments. Simultaneously, the protective oxide layer formed by aluminum and manganese provides excellent corrosion resistance in humid, dusty, or general industrial atmospheres. While not suitable for seawater or strong acid/alkali environments, brass press roller bearings perform exceptionally well in most industrial applications, providing users with stable and reliable support.

Different equipment has varying structural requirements for bearings. Therefore, Heavy Duty Press Roller Brass Bearings are designed with this in mind, and can be manufactured with various structures such as oil holes, grease grooves, and flanges to support reciprocating, rotating, and oscillating motions. This structural flexibility allows brass pressure roller bearings to be widely used in connecting rods, guide pillars, and guide sleeves of forging presses, as well as in sector roller bearings of metallurgical continuous casting machines, mold guide pillars and slide plates of injection molding and die casting machines, joints of engineering machinery, and sliding supports of mining equipment.
