1. Smooth surface, can withstand slight wear, hardening treatment can improve work efficiency.
2. Widely used in agricultural equipment, textile machinery, printing machinery, mechanical transmission and other industries that require steering drive.
3. Not easy to deform, high tensile strength, stable performance, large load-bearing capacity, smooth surface and easy maintenance.
Purchase Instructions:
1. The gear material is 45 steel, and the inner hole is positive tolerance 0-0.04. There may be a few burrs at the scene, which is normal.
2. The gear surface has blackening treatment and high-frequency quenching treatment, which is a material with a hardness of 45 steel. The surface hardness is about 40-45 degrees.
3. Because the effective tooth height is 12mm, the remaining position seems to have teeth, but it is not rolled in place, so the two gears are not suitable for parallel bite! Gear outer dimensions (except inner hole accuracy) may vary slightly from batch to batch. Please refer to the actual product!
