Shoeing replacement parts include mechanical assemblies, power transmission elements, and consumable components used in industrial shoe sewing and forming machines. These parts are manufactured from 42CrMo4 alloy steel, cold work tool steel, and martensitic stainless steel. Base material tensile strength ranges from 900 to 1200 megapascals, and final hardness after heat treatment is between 48 and 60 HRC. Dimensional tolerances for shafts and pins are specified within h6 to h8 classes according to ISO standards. Surface roughness of sliding components is maintained below Ra 0.8 microns. Corrosion resistant coatings such as electroless nickel with 10 to 25 micron thickness are applied.

The structural design of shoeing replacement parts is based on Hertzian contact stress and bending fatigue analysis to ensure a service life exceeding 10^6 cycles. Gears are manufactured with modules from 1 to 3 millimeters and DIN accuracy classes 7 to 9. Assembly clearance between moving parts is typically defined between 0.01 and 0.04 millimeters. Bearings are balanced and lubricated for rotational speeds from 600 to 3000 rpm. Wear resistance of engaged surfaces is enhanced through induction hardening to depths of 1 to 2 millimeters. Quality control includes functional testing, three dimensional measurement, and precise hardness evaluation.You can order and buy copuling from Iran by contacting us through whatsaap and email.
