GE 20 DO 2RS E INA 20x35x16 Spherical Plain Bearing

Product Overview

GE 20 DO 2RS E INA is a radial spherical plain bearing with dimensions of 20x35x16 mm, designed for bearing arrangements involving oscillating motion, tilting movement and slow rotational motion. The spherical sliding contact allows the bearing to accommodate angular misalignment between the shaft and housing. The 2RS configuration provides sealing on both sides to protect the sliding surfaces against external contamination.

Industrial Applications

INA GE 20 DO 2RS E is suitable for hydraulic cylinders, linkage systems, articulated joints, construction machinery, agricultural equipment, material handling systems and industrial mechanisms. Spherical plain bearings are particularly useful where high radial loads occur together with oscillating movement or angular displacement that conventional rolling bearings are not designed to accommodate.

Construction

The bearing consists of an inner ring with a spherical convex outside surface and an outer ring with a corresponding concave sliding surface. This geometry permits angular movement between the rings. 2RS seals on both sides help protect the sliding contact from dust and contamination while retaining lubricant within the bearing arrangement.

Material

The bearing uses steel components with sliding surfaces designed for high mechanical loading and oscillating operation. The steel-on-steel sliding contact requires appropriate lubrication for reliable operation. Service life depends on load, oscillation angle, sliding velocity, lubrication, temperature, contamination and correct shaft and housing fits.

FAQ

What are the dimensions of GE 20 DO 2RS E INA?

The bearing has a 20 mm bore diameter, 35 mm outside diameter and 16 mm outer ring width.

Why is the inner ring wider than the outer ring?

The inner ring has a width of approximately 20 mm, providing the geometry required for articulation and connection within the mechanical assembly.

What does 2RS mean in GE 20 DO 2RS E?

2RS indicates sealing on both sides, helping protect the spherical sliding surfaces from contamination.

Can GE 20 DO 2RS E accommodate shaft misalignment?

Yes. The spherical sliding surfaces allow angular movement between the inner and outer rings, accommodating alignment deviations within the bearing's specified limits.

Where is this spherical plain bearing typically used?

Typical applications include hydraulic cylinders, linkage mechanisms, articulated joints, construction machinery, agricultural equipment and material handling systems.
