55mm x 400mm Universal Hardened Greaseable Pin

Universal Hardened Greaseable Bucket Pin

Universal Hardened Greaseable Bucket Pins are precision-machined replacement pins designed for excavators, backhoe loaders, wheel loaders, mini excavators, and other construction equipment equipped with greaseable bucket assemblies. Manufactured from high-strength alloy steel and heat treated for maximum durability, these pins provide excellent wear resistance, high load capacity, and long service life in demanding operating conditions.

What is a Greaseable Bucket Pin?

A Greaseable Bucket Pin is designed to operate with a centralized or manual lubrication system. Unlike Dry (Non-Greasable) Pins, it features internal lubrication passages and a grease fitting (zerk fitting), allowing grease to be supplied directly to the contact surfaces between the pin and the bushings. Regular lubrication minimizes friction, reduces wear, and significantly extends the service life of the entire pivot assembly.

Heat-Treated Hardened Steel

Each pin is manufactured from high-quality alloy steel and undergoes precision heat treatment to achieve a hardened wear-resistant surface while maintaining a tough and durable core. This combination provides outstanding resistance to abrasion, impact loads, and deformation during continuous heavy-duty operation.

Integrated Lubrication System

Internal grease passages distribute lubricant throughout the working surfaces, while the grease fitting allows fast and convenient maintenance using standard grease guns. Continuous lubrication protects both the pin and bushings, reducing operating costs and extending component life.

Typical Applications

Universal Hardened Greaseable Bucket Pins are widely used in bucket pivot joints, linkage systems, boom and arm connections, quick couplers, and other moving assemblies where regular lubrication is specified by the equipment manufacturer. They are suitable for OEM replacement, preventive maintenance, repair, and machinery rebuilding.
