Rod end with female thread, KCRM, spherical ball iglidur® W300, mm

igubal® rod end bearing with female thread
 
igubal® rod ends are corrosion-resistant can be used without problems in harsh environments. In moist or wet environments, they are resistant to weak acids and alkalines. Their resistance to dirt and dust should be noted.
 
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
 
In standard spherical bearings, the spherical ball is made from iglidur® W300 material, which is known for lowest coefficients of friction in dry operation and extremely low tendency to stick-slip. This is especially important for low loads and very slow movements.

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 If rotation speeds higher than 0.5 m/s are required If very high tensile and axial forces occur When applications with hydraulic cylinders are planned If diameters above 30 mm are required Use our filter options to find the suitable product

Tolerances
The 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 bore 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
 
Coefficients 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 benefit of this plastic/steel plain bearing arrangement is that high speeds are possible even in dry operation. Taking the radial loads into account, maximum surface speeds up to 0.5 m/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
 
Both the spherical ball made of iglidur® W300 and the housing made of igumid G are resistant to weak alkalines, weak acids and fuels, as well as 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 coloration) of the spherical ball due to UV radiation and other weathering does not affect the mechanical, electrical or thermal properties.
