Ball and socket joints compensate
misalignment
Ball and socket joints are more than simple links for moving applications, they can crucially simplify the construction and improve the technical merits of an application.

How energy chains and polymer bearings benefit
In 'question and answer' mode, Matthew Aldridge, Product Director, igus (UK), explains how Energy Chain Systems, polymer bearings and Chainflex cables can benefit the machine tool industry.
Linear bearings are small and maintenance-free
Small, lightweight, quiet running, high-speed linear bearing system's hard anodised aluminium rails, iglidur J polymer sliding strips and cast carriages are maintenance free and repel dirt.
On this basis igus has optimized their in-line and right-angled ball and socket joints.
The consequent three-part design has a wear resistant iglidur polymer liner, which guarantees an exceptional service life.
It also absorbs micro vibrations and minimizes noise and can be installed rapidly and easily by hand.

High-speed linear bearing system repels dirt
When a small, lightweight, quiet running, high-speed linear bearing system is required, a miniature linear ball bearing system is free of maintenance, repels dirt and resists chemicals.
Linear guide saves space, needs no lubrication
To combine variety, make the best possible use of existing space and all without the need for lubrication were the specifications laid down when producing a new linear guide.
Dry-running linear bearing offers longer life
New maintenance-free, dry-running linear bearing design results in longer life, higher precision and increased load capacity when compared with ball bearing systems.
The retention forces are much higher than the joining forces and guarantee stability even in the most extreme applications.
The new DIN 71802 polymer ball and socket joint from the igubal range can be used as a 90deg coupling element for pneumatic cylinders, gas struts and tie bars and is available with M5, M6, M8 and M10 threads.
Since it automatically adjusts any misalignment, the design is greatly simplified.
Applications in a wide range of industries - the ball and socket joints are maintenance free, corrosion and wear resistant.
Temperature fluctuation from -30deg C to + 80deg C is no problem for ball and socket joints.
The combination with metallic DIN parts like rivet pins and threaded ball studs is also attractive for designers.
The inner liner may consist of one of 20 possible iglidur materials depending on the application.
This broad selection, together with the compact design, allows numerous application possibilities.
They can be used in the agricultural industry, where the environment requires the joints to be maintenance free and insensitive to abrasion.
Tractors and precision sowing machines benefit from design features tolerant of dirt and resistant against manure.
The igubal ball and socket joints are also used in the throttle lever mechanism found in special purpose vehicles.
Convertible vehicles require reduced noise, no need for maintenance and misalignment compensation.
In this case the plastic housing is combined with a metal ball stud.
Corrosion resistance and low weight are important for the lift mechanism of a bicycle trailer.
The ball and socket joints can even be applied where chemical resistance is needed or hygiene regulations apply.
Cost, weight reduction and corrosion resistance are major concerns in the rail industry, which is why a leading manufacturer of rail ventilators chose ball and socket joints from igus.
igus' innovative ball and socket joints have also reached the field of music: in an organ the parts connect the tie bar, which links the keys via the blower up to individual pipes.
Once again low weight and vibration damping are the advantages.
Predictable lifetime - Igus is the first manufacturer to put bearing technology online so that a complete bearing lifetime calculation is only a click away.
The only requirement is to enter some parameters of the application into the fields and immediately an expert system will calculate the lifetime online.
This is not merely a theoretical calculation: the basis of all calculations is data obtained from practical tests conducted continuously in igus laboratories. Request a free brochure from Igus UK ...
