Premium Quality Pins and Bushings for Heavy Machinery
Our pins are produced from high quality steel and differ from standard market products with their superior physical and chemical properties. Each production process starts with material control, stock verification and quality inspection. Materials are tested for hardness, spectrometric analysis, microstructure and cleanliness before machining and heat treatment.
Pin and Bushing Production Process
1. Material Selection
High quality steel materials such as 1020, 1050, 4140, 42CrMo4, EN19, CK50 and equivalent grades are selected according to the application and working load.
2. Quality Testing
Hardness, chemical composition, spectrometric analysis and microstructure checks are performed before production starts.
3. CNC Machining
Pins and bushings are machined with CNC technology for accurate dimensions, smooth surfaces and correct fitting tolerances.
4. Heat Treatment
Induction hardening and heat treatment processes are applied to reach the required surface hardness and core strength.
5. Surface Protection
Chrome coating, polishing, oiling or painting can be applied to increase corrosion resistance and surface quality.
6. Marking & Packing
Pins are marked according to brand, model or part number and packed securely for international delivery.
