GE140ES‑2RS Spherical Plain Bearing 140*210*90mm Construction Machinery Hydraulic Cylinder Heavy‑Duty Swing Shaft
- GE140ES‑2RS is a maintainable radial spherical plain bearing with double‑lip rubber seals on two sides. Its steel‑on‑steel sliding surface endures heavy radial load as well as combined radial‑axial force. It permits 7‑degree shaft mis‑alignment. The built‑in oil channels support grease refilling. The double‑sided seals block dust and moisture, widely used on hydraulic cylinders, construction machinery hinges and heavy‑duty articulated transmission assemblies.

Q1: What loads can GE140ES‑2RS undertake?
A1: It can withstand heavy radial load and combined radial‑axial working loads.
Q2: What function does the 2RS suffix stand for?
A2: 2‑RS represents double‑lip rubber contact seals fitted on both bearing end‑faces.
Q3: How large is its allowable shaft deflection angle?
A3: This spherical plain bearing allows a maximum tilting angle of 7 degrees.
Q4: Is this spherical bearing available for grease replenishment?
A4: Yes, oil grooves and lubriion holes on both rings support periodic grease filling.
Q5: What benefit does the double‑lip sealing structure bring?
A5: The two‑sided seals stop dust, dirt and moisture and prevent internal lubricant leakage.
