INA GE 40 DO-2RS Spherical Plain Bearing 40x62x28 mm

AI Overview

The INA GE 40 DO-2RS is a premium radial spherical plain bearing with dimensions of 40x62x28 mm, designed for applications involving heavy radial loads, oscillating movements and shaft misalignment. Manufactured by INA, a brand of the Schaeffler Group, this bearing features a steel-on-steel sliding contact and double 2RS rubber seals that protect the sliding surfaces from dirt, moisture and contaminants.

Designed in accordance with DIN ISO 12240-1, the GE 40 DO-2RS provides exceptional durability, shock resistance and long service life in demanding industrial, agricultural and construction environments.

What Makes INA GE 40 DO-2RS Different?

Key advantages include:

• Genuine INA product
• Schaeffler engineering
• Radial spherical plain bearing
• Steel-on-steel sliding contact
• Double 2RS rubber seals
• High radial load capacity
• Supports axial loads in both directions
• Excellent shock and vibration resistance
• Misalignment compensation
• Long operating life

Construction and Operating Principle

The bearing consists of:

• Inner ring with a spherical outside surface
• Outer ring with a matching spherical inside surface
• Hardened steel sliding surfaces
• Double rubber seals (2RS)
• Lubrication grooves and holes

The spherical sliding surfaces allow oscillating movement and angular misalignment while transmitting very high radial loads and moderate axial loads. Unlike rolling bearings, spherical plain bearings operate through sliding contact, making them highly resistant to shock loads and low-speed oscillating motion.

Material Properties

The bearing features:

• Hardened bearing steel rings
• Steel-on-steel sliding surfaces
• High wear resistance
• Excellent fatigue strength
• High impact resistance
• Long service life
• Re-greasable design
• Reliable operation under severe conditions

Typical Applications

INA GE 40 DO-2RS is commonly used in:

• Hydraulic cylinders
• Construction machinery
• Agricultural equipment
• Excavators
• Loaders
• Cranes
• Industrial linkages
• Suspension systems
• Material handling equipment
• Heavy industrial machinery

Typical Failure Symptoms

Replacement is recommended if any of the following symptoms occur:

• Excessive internal clearance
• Knocking or vibration
• Rough oscillating movement
• Damaged seals
• Corrosion
• Excessive sliding surface wear
• Grease leakage
• Loss of operating precision

Recommended During Maintenance

During replacement it is recommended to inspect:

• Shaft condition
• Housing bore
• Alignment
• Lubrication quality
• Seals
• Mating components
• Mounting procedure
• Shock loading conditions
• Housing cleanliness
• Pin or shaft wear

FAQ

What does GE DO-2RS mean?

GE identifies a radial spherical plain bearing, DO indicates a steel-on-steel sliding contact design requiring periodic lubrication, and 2RS means the bearing is fitted with rubber seals on both sides.

Does the bearing require lubrication?

Yes. The INA GE 40 DO-2RS is designed for periodic re-lubrication to maximize service life and maintain optimal performance.

Can it support axial loads?

Yes. In addition to very high radial loads, the bearing can also accommodate moderate axial loads in both directions.

Where is INA GE 40 DO-2RS commonly used?

It is widely used in hydraulic cylinders, construction equipment, agricultural machinery, suspension linkages, cranes and industrial mechanical systems operating under heavy loads.

What is the purpose of the 2RS seals?

The double rubber seals protect the sliding surfaces from dust, dirt and moisture while helping retain lubricant inside the bearing, significantly extending service life.
