Buy HITACHI RAM BUSHING 70 X 75 X 40MM HEIGHT | Tonkee®

Material Composition:
Ram bushings are typically made from high-strength materials such as bronze, steel, or other alloys to withstand the extreme pressures and wear and tear experienced in heavy machinery applications.

The choice of material depends on the specific requirements of the hydraulic system.

Dimensions:
The dimensions you mentioned (70 x 75 x 40mm height) likely refer to the outer diameter, inner diameter, and height of the bushing, respectively. These dimensions are crucial to ensure a proper fit within the hydraulic cylinder and its associated components.

Tolerances:
Precision is essential in manufacturing ram bushings. Tight tolerances ensure that the bushing fits securely, preventing leaks and minimizing friction, which can extend the lifespan of the hydraulic cylinder.

Surface Finish:
The surface finish of the bushing is vital for reducing friction and preventing premature wear. Many ram bushings have a polished or plated surface to enhance their durability and performance.

Lubrication:
Some ram bushings come with built-in lubrication channels or grooves to ensure proper lubrication of the moving parts within the hydraulic cylinder.

This helps reduce friction and heat generation.

Load-Bearing Capacity:
Ram bushings must be designed to handle the specific load and pressure requirements of the hydraulic system. They should be able to withstand the forces generated during the extension and retraction of the hydraulic cylinder.

Compatibility:
It's crucial to ensure that the ram bushing is compatible with the particular make and model of the heavy machinery, such as HITACHI equipment in this case. Compatibility ensures a proper fit and reliable performance.

Maintenance and Replacement:
Over time, ram bushings can wear out due to continuous use and exposure to harsh conditions. Regular inspection and maintenance are necessary to identify when a bushing needs replacement to prevent costly damage to the hydraulic system.
