Our products

Timing Chain Solutions, distributes only high quality automotive timing chains, these are manufactured by the worlds leading companies of timing chain design and production for
modern and classic motorsport, primarily for trade.

Sole U.K. distributor for IWIS Automotive Chain

IWIS Roller Chain - Simplex and Duplex

Simplex and Duplex roller chains with a 3/8" pitch are used primarily in timing drives, oil pump drives and drives for auxiliary units, especially for automotive engines. The chain is acoustically optimised with gap damping between roller and bush plus excellent wear resistance for high-speed applications. Owing to its smaller pitch, a roller chain with an 8 mm pitch cuts the weight and consequently reduces the centrifugal forces and impact speed.  It is therefore ideal for downsizing to timing drives with moderate loads.

Chains are available in both British sizes ranging from 7 mm - 8 mm and 3/8” and American Standards in sizes ranging from 6.35 mm – 76.20 mm. multiple pitch sizes are available to suit individual requirements, call our sales hotline for details. The chains high quality is based on each individual part being technically perfect during the manufacture process, from using high-grade heat treated steels to tolerance and surface quality; these standards conform to the requirements of ISO 9001.

These chains are characterised by an above-average service life due to excellent wear resistance, high consistency, matchless precision and considerably higher breaking strength and fatigue strength than required by ISO standards.  All IWIS chains are pre-stretched and are provided with a highly efficient initial lubrication. Simplex and Duplex roller chains which include a 3/8” pitch are commonly used on the majority of automotive engines.

IWIS Bush Chain - Simplex and Duplex

The chain with excellent wear resistance and minimal friction losses.

The Simplex and Duplex bush chain with a 3/8” pitch was designed for timing drives with more exacting requirements such as automotive engines.  Owing to their small pitch, bush chains with a pitch of 7 mm or 8 mm cut the weight and consequently reduce the centrifugal forces and impact speed. They are therefore particularly suited to high-speed drives (e.g. mass balancing drives).  All chains are available in both British and American Standards in multiple pitch sizes to suit individual requirements, call our sales hotline for assistance.

Simplex and Duplex roller chains which include a 3/8” pitch are commonly used on the majority of automotive engines.

IWIS Inverted Tooth Chain

The virtually silent chain with excellent wear resistance.
In order to handle higher power transmission requirements such as for vehicle transmission systems for example, transmission chains in the form of inverted tooth chains (also known as silent chains) are used.

The meshing of the toothed links with the sprocket gives this chain optimum acoustic properties for timing drives where acoustics are crucial, especially for automotive engines. The 8 mm pitch is also suitable for higher load chain drives, while the low weight of the 6.35 mm pitch makes it ideal for downsizing timing drives with moderate loads. All chains are available in both British and American Standards in multiple pitch sizes to suit individual requirements, contact our sales hotline for assistance.

REGINA - Triplex

Triplex Bush or Roller chains for engine timing drives (cam drives, oil pumps, water pumps). Variations are to fit most automotive applications, these chains from the Italian based Regina have had constant research and development making these chains some of the most innovative and high quality chains in the market. Triplex chain is available as 3/8" (5.72 mm) Pitch x Width – Endless. All Triplex chains are available in both *European and **American Standards in multiple pitch sizes to suit individual requirements, call our sales hotline for assistance.

Three product ranges available include:
 1. (STD) ISO/ ANSI norms, 2. (REINF H) Reinforced heavy duty series with thicker side plates 3. (REINF S) Reinforced s-type.
*  European Series, manufactured to ISO 606 norms, mainly used in Europe for power transmissions - available as 1, 2, 3 and 4 strands of rollers.
** American Series, manufactured to  American standards ANSI B29.1 which is included in the ISO/R 606. Similar to the European Series but offer higher fatique resistance due to their design charecteristics. On the other hand they have a lower breaking load than the European chains.

A wide set of tests aimed at assessing mechanical performances, such as life endurance, materials composition, chemical compatibility, etc. is performed to validate any new product prior to its launch on the market. These are performed at Regina’s lab which is fully equipped for metallographic, chemical and mechanical tests facilities.
