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.

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 Use our filter options to find the suitable product

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 polymer/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 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 bearing ring made of iglidur® J is resistant to weak alkalines, weak acids as well as fuels and all types of lubricants. The moisture absorption of igubal® spherical bearings is approximately 1.3% of its regular weight in standard environments. The saturation limit submerged in water is 6.5%. This must be taken into consideration in light of the prevailing environmental conditions. If a lower moisture absorption is required, it is worthwhile having a look at the various materials available.
 
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.
