The construction consists of a special hollow pin chain and dismountable top plates. In order to secure the plates tightly and safely there is a long pin attached to the bottom side of the plate, which feeds into the hollow pin of the chain and is subsequently affixed by means of circlips. Opening the chain for mounting the plate is not required.
An additional short pin twist-secures the top plates by meshing with the respective plate. The surfaces of the carrier top plates are smooth, and they are specially coated to increase wear resistance and corrosion protection. The distance of the sickle-shaped top plates to each other is minimal and allows for an unrestricted movement even around narrow bends. The bottom bearing areas of the top plates are sufficiently large enough to transmit the weight of the goods onto a guide rail.
The type with rolling pivot joints has an important advantage compared to the tooth chain with bushings in that bearing and rolling pivots roll off one another. In contrast to bolt joints there is no sliding friction in the joints resulting in a high degree of efficiency. Wear and warming are minimized. Inverted tooth chains can be divided into different subgroups depending on the respective application.
Inverted tooth drive chains
Inverted tooth drive chains are the optimal solution for requirements exceeding those met by other chains (e. g. roller chains). They allow for low-backlash drives with exact positioning. They are also highly effective, inured to vibration and have minimal noise emission.
Inverted tooth conveyance chains
Inverted tooth conveyance chains are used for application with particularly high transport weights. They run very smoothly and quietly. These chains can optionally be supplied with standard plates, with a ground back, or with special plates.
High-performance inverted tooth chains
High-performance inverted tooth chains are manufactured with staggered individual plates. Rolling pivot joints ensure optimal smoothness of running and minimal sliding friction resulting in low wear and a long life cycle. Due to individual plate arrangements different widths other than the standard ones are also possible.
Inverted tooth chains with bushings
Inverted tooth chains with bushings differ from other inverted tooth chains because pin joints are used. The chain is designed with tooth plates arranged in pairs.
Technical product information:
The meander-shaped chain guidance allows for a high storage capacity of tools under limited spatial conditions.
The ATC chain is designed as a Galle chain, and the plates turn on heat treated and coated bushings. Several tool holders are integrated in the bushings providing a gentle fit for the spindle cone of the respective tool. The axial pull-off force can be adjusted depending on the chain arrangement (tools lying, hanging or standing) and the tool weight.
ATC chains are manufactured to customers’ requirements with different pitches.
Technical product information:
They are comparable with roller chains according to ISO 606, but they have no rollers. This means, however, that their qualities as to noise behavior and wear are inferior to those of roller chains. Due to their robust design bush chains are mainly used as slow-running drive and conveyor chains under rough operating conditions, e. g. in mining or construction site equipment.
Technical product information:
In its range K&W Transmissies offers the possibility of low-maintenance and maintenance-free chains. Unlike regular chains, maintenance-free chains will continue to operate temporarily without lubrication or with insufficient lubrication. Low-maintenance chains feature a special coating and typically feature special hardening technology on the hinges. Special coatings increase the life of the chain – even with little maintenance! The special coating on the chain pins, bushings and rollers ensures that the chain is particularly resistant to periods, when the chain is not lubricated enough. The extended duration of the use of the chain increases the availability of machinery and equipment.
The Wippermann brand has the very popular Biathlon, Marathon and Triathlon series in its range. But HKKchain also has in its waterproof series a chain with properties that allow it to withstand temporary periods of dry running.
More information maintenance-free chains:
Apart from availability, operational safety and reliability, the fact that components are maintenance-free is getting more and more important in machine and plant construction. The use of Marathon chains always makes sense where relubrication or roller chains is either not possible or not desired, but where, nevertheless, a long life cycle is required.
For application areas with certain chain speeds and operating temperatures Wippermann can provide optimal solutions with Marathon chains. They work with a porous, oil-soaked sintered bushing, which is combined with a specially-coated pin to form a self-lubricating chain joint.
The dimensions of Marathon chains are according to ISO 606 so that every standard roller chain can be replaced by a Marathon chain. The breaking load of a Marathon chain exceeds the requirements or respective standards and is comparable to standard Wippermann chains as regards fatigue resistance.
Apart from the standard roller chains according to ISO 606, the Marathon range also comprises roller chains type series GL with straight plates, double pitch roller chains according to ISO 1275 and accumulator chains.

“Last week I stopped in for a chain for an old motorcycle.
It fits perfectly; I needed that half link.
Last weekend I rode Old Crocks (built in 1905) in Westhofen Germany and everything went well.
Thanks again for the good cooperation and prompt service.
As promised here are a few pictures.”
