Cylinder bushings with diamond-shaped oil grooved pockets,hardened steel bucket bushings, cylindrical and flanged type
Maximize the lifespan and performance of your machinery with our precision-engineered Hardened Alloy Steel Bucket Bushings. In extreme heavy-duty or high-impact applications, standard soft-alloy bearings often face the risk of deformation or premature surface fatigue. Our hardened and precision-ground steel bushings solve this by providing a high-strength, wear-resistant interface that maintains its dimensional stability exactly where it’s needed most.
Why Choose Steel Sleeve Bushings?
The primary purpose of utilizing high-grade steel alloys like ASTM 4120, DIN 25CrMo4, and 20CrMo is Structural Rigidity and Surface Hardness. By employing advanced heat treatment (quenching and tempering) and precision grinding processes, our steel bushings offer:
- Exceptional Load Bearing: Engineered with a specialized alloy containing manganese and vanadium to handle much higher static and dynamic loads while providing improved strength and toughness.
- Superior Impact Resistance: Features a hardened exterior for wear resistance while the interior remains ductile, allowing it to withstand heavy shock loads and punishing vibrations without cracking.
- Optimized Surface Finish: Precision-ground and tempered surfaces minimize friction and prevent galling, featuring an inner surface with spiral oil grooves, oil rings, and elliptical sockets for superior lubricant retention.
