Rod end made of zinc die-casting with female thread, KCRM, iglidur® J bearing ring, mm

igubal® metal 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.

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 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 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 recommended tolerances h6 and h9. Check 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. Without further ado, the maintenance-free igubal® bearing elements also allow linear movements of the shaft.

Chemical resistance of igubal® bearing elements

The bearing ring made of iglidur® J is resistant to weak alkalis, weak acids as well as fuels and all types of lubricants. The moisture absorption of igubal® spherical bearings is approximately 1.3% weight in standard climatic conditions. The saturation limit submerged in water is 6.5%. This must be taken into evaluation for applications. If a lower moisture absorption is essential, a look on to the different materials is helpful.UV resistance

The corrosion resistance of the 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.
