When a machine joint needs to pivot or tilt rather than spin continuously, a spherical plain bearing does the job. It consists of an inner ring with a spherical outside surface that slides against the outer ring, allowing angular misalignment and oscillating motion without rolling elements.
SKF's GE series uses the bore diameter as its size reference. The ES suffix denotes a version that calls for less upkeep than the basic design, and the 2RS suffix means rubber seals are fitted on both sides to keep out dust and moisture.
Typical installation points include tie rods, linkages for hydraulic or pneumatic cylinders, rod ends, and any connection where two components move at a changing angle—for example, the pivot of a cylinder that operates in different positions.
Since the bearing relies on a sliding contact rather than rolling elements, its lifespan depends heavily on proper initial lubrication and effective sealing. A 2RS version generally does not require scheduled relubrication in most uses, whereas an open bearing typically does.
Bore diameters in the GE series are widely standardized across manufacturers, so a matching size from another brand is often available. To confirm an equivalent, provide the bore diameter or the complete part number. Request a quote from MR Industrial Accessories through WhatsApp or email.

Frequently asked questions
- How does a spherical plain bearing differ from a standard ball bearing?
- A spherical plain bearing has no rolling elements; the inner ring slides directly on the outer ring. It is made for misalignment and oscillating movement, not for continuous high-speed rotation.
- What does the ES suffix indicate in the GE series?
- It identifies a variant that needs less maintenance than the standard design of the same series, usually because of the sliding surface material or treatment.
- Does a sealed 2RS spherical plain bearing require relubrication?
- In most applications, no, because the seals protect the sliding surface. An open spherical plain bearing usually does need periodic relubrication.
