Product Description
Product Overview
20CrMo hardened steel bushings are engineered for extreme-duty applications requiring high performance, minimal maintenance, and extended service life. Manufactured from 20CrMo sorbite steel with advanced surface treatments, these bushings deliver superior lubrication and durability.
Material Specifications
- Base Material: Sorbite Steel
- Base Hardness: 280-330HV0.3
- Carburized Treatment with hardness of HRC57-62
- Carburized layer thickness: 0.8-1.2mm
Surface Treatments
- QPQ Treatment hardness: >550HV
- QPQ Treatment thickness: 0.15-0.4mm
- Multiple self-lubricating coatings with designed oil pockets
- Internal oil pockets store grease for continuous lubrication
Performance Advantages
- No additional oil or grease required for lubrication
- Operates at temperatures up to 300°C without bearing burn or journal sticking
- High load capacity with strong compression resistance
- High hardness (57-62 HRC) with low friction coefficient
- Excellent resistance to impact, wear, friction, and corrosion
- Eliminates common issues of traditional bushings: noise, frequent replacement, and maintenance
Industrial Applications
20CrMo hardened steel bushings are widely used in heavy machinery including excavators, rotary drilling machines, heavy-duty loaders, and diaphragm wall grabs.
