GK30DO Rod Ends 30mm Spherical Welding Joint Bearings for Hydraulic Cylinder
The GK DO is a hydraulic rod end bearing designed for use in heavy-duty applications. It is a maintenance-requiring bearing, meaning it needs to be periodically lubricated to ensure a long service life. The design includes a spherical inner ring and a housing with a grease nipple for easy relubrication.
Main Applications:
Due to its robust design, the GK DO is suitable for a wide range of industrial applications, including:
Hydraulic cylinders in construction machinery
Agricultural equipment
Material handling systems
Various linkages that experience heavy loads and oscillating movements
Maintenance:
As a maintenance-requiring bearing, the GK DO needs regular lubrication. The frequency of relubrication depends on the operating conditions, such as load, speed, and environment. Regular maintenance is crucial to prevent premature wear and ensure the bearing operates at its optimal performance.

FAQ: How to weld GK30DO spherical bearings for hydraulic cylinders?
The GK30DO has a circular welding face and a centring pin on its shank base. This design aids in precise alignment and welding.
The bearing’s housing is made from a weldable material, such as structural steel (e.g., S355J2G3), which is suitable for the high heat of welding.
It’s important to avoid direct welding heat on the bearing itself, as this can destroy the internal components, deform the rings, and damage the lubricant. You must weld the bearing shank to the piston rod end or cylinder base.
For best results and to maintain the component’s integrity, a specialized process like friction welding is often used for hydraulic cylinder rod ends. This process provides a high-strength weld with minimal heat input, protecting the bearing.
