Product description
igubal® rod end bearing with second generation 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.
 
Housing made from igumid G, an extremely impact-resistant, long-fibre-reinforced polymer. Suitable for temperatures from -40°C to +90°C in long-term use
 
Here, the spherical ball is made from iglidur® J material, which is known for its low moisture absorption, low coefficient of friction during dry operation and an extremely low tendency to stick-slip. This is especially important for low loads and very slow movements.
  • Maintenance-free dry operation
  • Extremely cost-effective
  • No lubrication
  • High stiffening
  • 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
  • High vibration-dampening
  • Suitable for rotating, oscillating and linear movements
  • Inner rings mounted with extremely little clearance
  • Very lightweight

Typical application areas
  • Bicycle manufacturing
  • Plant construction
  • Packaging
  • Offshore

When to use it?
  • If you want to save weight
  • 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 really high tensile and axial forces occur
  • When applications with hydraulic cylinders are planned
  • If diameters above 30mm are required

Tolerances
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 plastic/metal plain bearings is that high speeds are possible even in dry operation. 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 spherical outer diameter of the spherical ball. The maintenance-free igubal® bearing elements also permit linear movements of the shaft.
 
Chemical resistance of igubal® bearings
 
The moisture absorption of the igubal® J spherical ball is approximately 0.3% of regular weight in standard environment. The saturation limit submerged in water is 1.3%.
 
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.
