pressure roller

Using 40Cr or 42CrMo as the base material, the precision forged blank undergoes a series of processes including normalizing, turning, gear hobbing, carbonitriding, heat preservation and tempering, precision grinding of the inner circle, and rust prevention treatment. The hardness of the quenching zone is HRC58-HRC62. The process is meticulous, and the finished products undergo strict quality inspection.

A variety of optimized tooth surface designs are available for users to choose from: herringbone tooth type, honeycomb round hole type, hole and straight tooth combination type, large spiral helical tooth type, ordinary straight tooth type, and through tooth type.

High-precision concentric grinding ensures precise fit between the inner circle of the pressure roller and the user's bearing, as well as the coaxiality requirements of the inner and outer circles of the pressure roller.
