The wheel body adopts a unique heat treatment method to ensure the surface hardness and hardness layer. The support has strong wear resistance, durable wear resistance, and perfect sealing design. Precision machined sealing surfaces. The series-wound sealing design can ensure the sealing effect of the product from the beginning to the end.
Wheel body: 40 manganese steel with good hardenability is used, which is quenched and tempered and medium frequency induction hardened to ensure its strength and wear resistance.
Shaft: 45# steel is used, tempered and surface quenched by medium frequency induction heating, the surface hardness is HRC45-55, and the depth of hardened layer is 3mm-6mm, which is comprehensive.
Floating seal: chrome-aluminum alloy, hardness 65~72, working surface roughness 0.1μm-0.2μm
O-ring: Butane-acrylonitrile copolymer is used to produce butadiene-acrylonitrile rubber raw material, which has good oil resistance and high temperature resistance.
The surface hardness of the guide wheel is HRC45-55, and the depth is 3mm-6mm.
