High-Performance Bushings & Sleeves: Empowering Equipment Upgrade with Robust Core Power

Precision Material Selection: Laying a Solid Foundation for Performance

• Gr15 Bearing Steel: A high-purity wear-resistant steel with uniform microstructure and excellent hardenability. It is an ideal choice for high-frequency rotating components, with surface hardness reaching HRC60-66, effectively resisting friction and extending continuous operation time of equipment.
• 20CrMnTi Alloy Structural Steel: Innately possesses excellent carburizing performance. After professional processing, it forms a "hard exterior and tough core" characteristic, with surface hardness up to HRC58-62 and core maintaining good toughness, easily coping with impact loads.
• 42CrMo High-Strength Alloy Steel: Combines high strength and high fatigue strength. After quenching and tempering, it boasts outstanding comprehensive mechanical properties, capable of withstanding complex bending and torsional loads, making it the core material for load-bearing components of automotive chassis.

Precision Crafting: Activating Material Potential with Advanced Processes

• Carburizing Treatment: Deep carburizing for materials like 20CrMnTi forms a dense hardened layer on the part surface, significantly improving wear resistance and contact fatigue strength. It perfectly adapts to impact working conditions of agricultural machinery during plowing and dynamic loads of automotive chassis.
• Vacuum Quenching: Precise temperature-controlled quenching in a vacuum environment avoids oxidation and decarburization, enabling materials to obtain uniform hardness distribution and excellent toughness, ensuring structural stability of components under extreme working conditions.
• Induction Hardening: Local high-frequency induction hardening for key working surfaces of 42CrMo precisely strengthens stress-bearing areas. While reducing material loss, it ensures high-strength performance of core parts to meet precision transmission requirements.
• Cryogenic Treatment: Ultra-low temperature cryogenic treatment at -196°C for quenched materials like Gr15 promotes full transformation of retained austenite, refines carbide particles, further improves material hardness, wear resistance and dimensional stability, reduces deformation risk during long-term use, and provides long-term guarantee for high-precision transmission.

Five Core Advantages: Solving Scenario Pain Points with Key Performance

Scenario Adaptation: Empowering Two Major Fields with Customized Solutions

• Agricultural Machinery Special: For harsh working conditions of tractors, harvesters and other equipment, 20CrMnTi + carburizing process or Gr15 material is selected. Its high wear resistance and impact resistance cope with dust, vibration and heavy loads in field operations, ensuring continuous operation during critical agricultural periods and reducing downtime losses.
• Automotive Chassis Special: Customized high-precision bushings and sleeves for key components such as transmission systems. After vacuum quenching and cryogenic treatment, they possess excellent strength, toughness and dimensional stability. Combined with high-precision characteristics, they effectively improve vehicle NVH performance, reduce driving vibration, and ensure driving safety and comfort.
