GE 90 DO INA Spherical Plain Bearing 90x130x60

Application of GE 90 DO INA Bearing

The GE 90 DO INA 90x130x60 is a spherical plain bearing designed for heavy-duty industrial applications requiring high load capacity and misalignment compensation. With an inner diameter of 90 mm, outer diameter of 130 mm and width of 60 mm, this bearing unit is commonly used in hydraulic cylinders, construction machinery, agricultural equipment and structural mechanical systems.

Unlike a standard ball bearing, a spherical plain bearing is engineered to handle high static and dynamic loads while allowing angular movement between shaft and housing. This makes the GE 90 DO particularly suitable for applications exposed to shock loads, oscillating motion and shaft misalignment.

Design Advantages - High Durability Under Heavy Loads

The GE 90 DO INA features a steel-on-steel sliding contact design, optimized for demanding operating conditions. This construction ensures high durability, resistance to impact loads and stable performance under continuous stress.

Its ability to compensate for misalignment increases the safety and reliability of the entire mechanical system. When installed in a properly dimensioned bearing housing, it forms a robust bearing unit capable of withstanding harsh industrial environments.

Precision manufacturing by INA guarantees dimensional accuracy, proper fit in the housing and long service life in heavy industrial operations.

FAQ - Frequently Asked Questions

What is the difference between a spherical plain bearing and a ball bearing?
A spherical plain bearing is designed to carry heavy loads and allow angular misalignment, while a ball bearing is mainly intended for rotational movement with limited misalignment tolerance.

Is GE 90 DO suitable for shock loads?
Yes, the steel-on-steel design provides high resistance to shock and dynamic loads.

How do I select the correct size?
Match the inner diameter (90 mm), outer diameter (130 mm) and width (60 mm) to the shaft and housing dimensions, considering load requirements and angular movement.

Does this bearing require lubrication?
Yes, steel-on-steel spherical plain bearings require proper lubrication depending on operating conditions.
