Rod end with female thread, EBRI / EBLI igubal®, spherical ball iglidur® R, imperial

igubal® rod ends with female thread

igubal® rod end bearings are corrosion-free and can be used without problems even under harsh conditions. In humid or wet environments, they are resistant to weak acids and alkalis. The insensitivity to dirt and dust should be emphasised.

Housing made of igumid G, particularly impact-resistant, long-fibre reinforced polymer. Long-term suitable for temperatures from -40°C to +90°C

The spherical ball is made of iglidur® R, a material that is characterised by the lowest coefficients of friction in dry operation and extremely low stick-slip tendency. 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 silent operation is required If you need an electrically insulating part If corrosion resistance is required In combination with pneumatic cylinders and gas struts When chemical resistance is required If high rigidity is required

When not to use it? If temperatures are higher than +90°C If rotation speeds of more than 0.5 m/s are to be achieved When really high tensile and axial forces occur When applications must be implemented with hydraulic cylinders If diameters above 30 mm 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 clearance in the standard product, which enables a secure operation even under high peripheral speeds. The hole of the spherical ball is produced to a standard tolerance range E10. Shafts should also meet tolerances between h6 and h9. Checking the inner diameter

Dynamic coefficients of friction and speeds

An important advantage of the maintenance-free igubal® bearing elements is that fast rotational movements of the supported shaft take place directly in the bearing spherical ball made of iglidur® materials. The advantage therefore lies in the plastic vs. steel relationship. Polymer produces lower friction and permits high speeds, even in dry operation. Taking the radial loads into account, maximum surface speeds up to 0.5m/s rotating can be attained. By contrast, rotations of the shaft are supported directly in the inner diameter of the spherical portion. The maintenance-free igubal® bearing elements also readily permit linear shaft movements.

UV resistance

The corrosion resistance of igubal® bearing elements makes them particularly interesting for outdoor use. igubal® bearings are permanently resistant to UV radiation. A small change in colour (dark colouration) of the spherical ball due to UV radiation does not affect the mechanical, electrical or thermal properties.
