Roller chains
Roller chains, high-profile projects
The knowledge and experience of the product specialists at K&W Transmissies is permanently deployed to increase production capacity and extend the lifetime of the chains. Their knowledge of applications and materials, which has been built up over the years, enables K&W Transmissies to respond directly to development. For this reason it has become a successful, leading provider of large and high-profile projects. Roller chains have to optimally perform under the most extreme conditions. The high-quality chains are also used in various applications, which enter markets worldwide via our customers. The customers of K&W Transmissies come from different sectors such as asphalt, automotive, waste incineration, concrete, biogas, breweries, cement, canned goods, wood and paper, insulation, internal transport, agriculture, machining, environment, offshore, recycling, passenger transportation, slaughter industry, stone industry, bulk materials, sugar, packaging, food and hydropower.
Nickel-plated, galvanized and stainless steel roller chains
Nickel-plated chains are used where chains are visible and you want to create a certain optical effect. All steel chains can in principle be nickel plated. The nickel layer on the steel parts does, however, result in a somewhat reduced breaking load. All steel chains can in principle also be galvanized.
Nickel-plated, galvanized and stainless steel chains are used in humid environments where corrosion is not desired, for example in the food industry. Stainless steel can be a solution if the corrosion protection offers insufficient protection. Stainless steel chains do have a significantly lower breaking strength than the steel or nickel-plated chains. Lubricating the chain is also a method that can prevent or reduce corrosion to a limited extent.
The stainless steel chains are manufactured from types of steel that are rust and acid-resistant. The DINN stainless steel chains are supplied standard without lubrication, which means that the customer has the option to adjust the type of lubrication to the circumstances and wishes under which the chain is used.
Carriers and extended pins
Roller chains are not only used to transfer a force, but are also used as a transport medium for goods. K&W Transmissies has a very extensive line of standardized carriers and/or extended pins. These come in both steel and stainless steel versions. The current production techniques of the Wippermann brand give the designer an almost unlimited freedom to deviate from the standard versions in order to allow the carriers to be produced according to one’s own wishes and insight. If required, the roller chains can be custom assembled with carriers and/or extended pins. There are also chains available with elastomers or vulcanized carriers. For more information about this, please see the option clips.
Clips
These clips are suitable for mounting on a Wippermann roller chain with straight side plates (type GL) and prevent direct contact between the product and the chain. The clips also increase the contact surface and thus offer safe transport.
Clips are available with thermoplastic elastomer (TPU) with a hardness of approximately 85 Shore A for the transport of particularly delicate and easily displaceable products. This clip ensures complete non-slip transport and effectively increases the friction coefficient between product and clip.
Straight side plates
Roller chains with straight side plates carry a load that presses directly onto the plates, making them suitable for sliding over a guide. The surface pressure is advantageously distributed over a larger surface area, as a result of which there is less wear on the guide and switching plates. K&W Transmissies supplies these chains (DIN 8187, DIN 8188) in various qualities from the different brands, in stainless steel, galvanized or nickel-plated steel. The roller chains can also be supplied with carriers and/or extended pins or with POM clips.
Maintenance-free chains Triathlon
The maintenance-free chain Triathlon HT is a maintenance-free, high load bearing special chain for use under temperatures of up to 200 °C.
Thanks to the special low friction chain joints the chain is extremely resistant even for the most difficult applications, thereby eliminating the need for relubrication.The perfectly coordinated materials make the Triathlon HT unique: coated pins, special coated rollers and in particular the innovative high-tech polymer bushings of the Triathlon HT guarantee outstanding wear resistance – even without relubrication.
With the Triathlon HT, Wippermann sets new standards for the many production processes for which the combination of high temperatures and sensitive components present particular challenges for the chains. In the automotive industry for instance, unwanted paint wetting with lubricant residues is avoided. In the electrical industry, hoisting and conveyor chains has to be complete dry without lubrication to avoid chemical reactions e.g. in casting resins.
- Coated bushings with high-tech polymer inserts
- Coated pin chains
- Coated rollers
- Highly resilient, low friction chain joints
- No relubrication required
- Lubricant-free for chain speeds up to 2.5 m/s
- Temperatures from - 30 °C to +200 °C
Maintenance-free chains Biathlon
The high-performance Biathlon chain shows its full advantages wherever the use of standard roller chains is not economical in the face of difficult maintenance conditions.
The special coating or chain pins and rollers allows for excellent dry-running operation characteristics and makes this chain particularly resistant in phases without sufficient relubrication. The extended wear life increases the availability of machines and plants.
The special surface coating of the Biathlon chain guarantees high resistance against abrasive and adhesive wear even in case of low lubrication. Thus fretting is avoided to a very large extent. Due to special finishing procedures, the surface has an optimal ductility despite its hardness.
The coating process is characterized by a reproducible layer thickness and an extraordinarily constant and even layer thickness on the chain components.

Roller chains zinc-plated
Zinc-plated chains are used in humid environments and where corrosion is undesirable.
In principle, all steel chains can be zinc-plated. If this corrosion protection still offers insufficient protection, stainless steel may be a solution. Stainless steel chains, however, have a significantly lower tensile strength than steel chains or zinc-plated chains.

Agriculture roller chains
Agriculture chains for extreme weather conditions and severe pollution by soil and manure
K&W Transmissies has a wealth of experience, when it comes to the great diversity of roller chains used in agriculture. Many applications are exposed to extreme weather conditions and severe pollution by soil and manure. These specific conditions, where durability and reliability are required, place high demands on the quality and performance of the applied chain. Further, the tooth form of the sprockets and the ability to discharge pollution play an important role. K&W Transmissies has already overcome several challenges in situations, that were decisive in the construction of agriculture-specific applications.
Gripper chains
These Gripper roller chains are heavily loaded and need to be highly resistant to corrosion.
Over the years K&W Transmissies, along with its supplier Wippermann, has gained extensive knowledge and experience in producing and improving gripper chains. These chains are heavily loaded and need to be highly resistant to corrosion. One of the most important requirements placed on the gripper chains is the length accuracy and tolerance ranges of the components. Using high-quality measuring equipment, these chains are classified according to their tolerance ranges and colour coded. This ensures an accurate flow and optimal guidance of the foil after installing the chain in the machine.
