INA GE50-DO-2RS

INA Spherical Plain Bearing GE50-DO-2RS

Description

This is a GE50-DO-2RS spherical plain bearing, a standard component designed according to DIN ISO 12240-1. It is engineered to handle heavy static and dynamic loads while accommodating misalignment. The ‘DO’ designation indicates that it is a steel-on-steel bearing, and the ‘2RS’ signifies that it is sealed on both sides with contact seals, providing excellent protection against contamination and retaining grease for long life. This bearing is suitable for a wide range of industrial and mechanical applications.

Specifications

• Model: GE50-DO-2RS
• Type: Spherical Plain Bearing
• Bore Diameter (d): 50 mm
• Outer Diameter (D): 75 mm
• Inner Ring Width (B): 35 mm
• Outer Ring Width (C): 28 mm
• Sealing: 2RS – Contact seals on both sides
• Lubrication: Features lubrication groove and hole in outer ring

Application

Ideal for use in hydraulic cylinders, construction machinery, agricultural equipment, and other applications where pivoting movements and misalignment must be accommodated under heavy loads.

Country of Origin

Typically manufactured in Germany, but as a global standard, production may occur in other countries.

CO2 Impact

Opting for this reused component prevents the emission of approximately 1.02 kg of CO2, which would have been generated during the production of a new one. This saving is equivalent to the CO2 absorbed by a small tree over several months.

FAQ

What is the main advantage of the ‘2RS’ seal on this GE50-DO-2RS bearing?
The ‘2RS’ designation indicates that the bearing has contact seals made of nitrile butadiene rubber (NBR) on both sides. These provide excellent protection against contaminants like dust and moisture, while also retaining the lubricant, making it a maintenance-free solution for many applications.

Can this bearing be re-lubricated?
Yes, the design includes a lubrication groove and hole in the outer ring. This allows for re-lubrication during its service life, which is crucial for applications with high loads, oscillations, or exposure to harsh environments, thereby extending its operational lifespan.

Is this bearing suitable for high-speed rotation?
No, spherical plain bearings like the GE50-DO-2RS are designed for slow rotational or oscillating movements and accommodating misalignment. They are not intended for high-speed continuous rotation like ball or roller bearings.
