Product description
igubal® metallic rod end bearing with male thread
igubal® rod ends are corrosion-resistant and can be used without problems in harsh environments. In moist or wet environments, they are resistant to weak acids and alkalines. Rod ends are also resistant to dirt and dust.
Steel housing for very high loads. Suitable for temperatures from -40°C to +90°C in long-term use
  • Maintenance-free dry running
  • Extremely cost-effective
  • No lubrication
  • High rigidity
  • Durable in varying loads
  • Compensation for misalignment
  • Compensation for edge loads
  • Resistant to dirt, dust and lint
  • Resistant to corrosion and chemicals
  • Can be used in liquid media
  • Vibration-dampening
  • Suitable for rotating, oscillating and linear movements
  • Inner rings mounted with extremely little clearance

Typical application areas
  • Mechanical engineering
  • Plant construction
  • Rail industry
  • Automation
    You will find plenty of additional application areas at our Browse all Industries
When to use it?
  • When really high tensile and axial forces occur
  • For rotating, oscillating and linear movements
  • If high-frequency oscillations/vibrations occur
  • If low-noise operation is required
  • If you need an electrically insulating part
  • If corrosion resistance is required
  • In combination with pneumatic cylinders and gas struts
  • If chemical resistance is required
  • If high rigidity is required
When not to use it?
  • If temperatures are higher than +90°C
  • When rotation speeds higher than 0.5m/s are required
  • When applications with hydraulic cylinders are planned
  • If diameters above 30mm are required

igubal® bearing elements can be used with different tolerances according to each application. They are designed with a large bearing clearance in the standard product, which enables secure operation even under high peripheral speeds. The hole of the inner ring is produced to a standard tolerance range E10. Shafts should also meet recommended tolerances h6 and h9. Check the inner diameter
Coefficient of sliding friction and speed
One important advantage of maintenance-free igubal® spherical bearings is that rapid rotary movements of a mounted shaft take place directly in the spherical portion made from iglidur® materials. The advantage of these polymer/metal plain bearings is that high speeds are possible even when dry running. Taking the radial loads into account, maximum surface speeds up to 0.5m/s rotating can be attained. In contrast, angular movements of the spherical bearings take place at the outer diameter of the spherical ball. The maintenance-free igubal® bearing elements also permit linear movements of the shaft.
Inner ring for food applications
The bearing ring made of iglidur® A160 is detectable and made of FDA and EU 10/2011-compliant materials.
UV resistance
The corrosion resistance of igubal® bearings is of special value for outdoor applications. igubal® bearings are permanently resistant to UV radiation. A small change in colour (dark colouration) of the spherical ball due to UV radiation and other weathering does not affect the mechanical, electrical or thermal properties.
