    Product advantages

    1、Our caster bobbins are made of manganese steel, which is a mixture of steel and carbon with impact and wear resistance properties that extend the life of the caster.


    2、Our caster wave plate uses lithium molybdenum disulfide grease, which has strong adsorption, waterproof and high temperature resistance, and can still play a lubricating role in harsh environments.


    3、The surface of our caster bracket adopts the spraying process, the anti-corrosion and anti-rust grade reaches 9, the traditional electroplating grade 5, galvanized only grade 3. Zhuo Ye manganese steel casters are more suitable for use in the harsh environment of wet, acid and alkaline.
