Who is iwis and what does it make?
iwis is a German manufacturer of drive and conveyor chains, with roots of more than a century in Germany and extensive production in North America as well. The range includes roller chains for power transmission, conveyor chains for production lines and matching sprockets. From the portfolio we can quote standard roller chains, conveyor chains for the food industry and CLA automatic lubrication systems for continuously operating lines.
In the industrial chain category, iwis covers the segment of precision roller chains and special wear-resistant chains. MEGAlife chains have a seamless sintered bush and a pin with a wear-resistant coating; they need no scheduled relubrication within the intended service life and, under suitable conditions, can reach a service life of up to three times that of a standard roller chain. The b.dry range brings together stainless steel roller chains, used mainly in the food industry or where the chain must be cleaned frequently. The portfolio comprises around 95,000 unique products, manufactured at 32 locations worldwide.
For installations in Romania, iwis makes sense on packaging and conveying lines in the food industry, where the stainless b.dry chains are useful, and on industrial drives where the long service life of MEGAlife chains reduces stoppages for chain replacement. Correct selection of the pitch and bush type directly affects service life.
What do we supply from the iwis range?
| Product | Description |
|---|---|
| MEGAlife Series Roller Chains | Roller chains for power transmission, built with a seamless sintered bush and a pin with a wear-resistant coating. Chains with no scheduled relubrication within the intended service life, according to the manufacturer's technical documentation, which reduces maintenance stoppages on heavily loaded drives. They are used in industrial drives, agricultural machinery and continuously operating lines. For a quotation we need the chain pitch, the number of links and the type of joint (with connecting link or pressed). |
| b.dry Stainless Steel Roller Chains | Stainless steel roller chains from the b.dry range, used mainly in the food industry or in applications with frequent cleaning. The customer must specify the chain pitch and the type of joint for compatibility. |
| CLA Automatic Lubrication Systems | Centralised lubrication systems, mounted on chain drives that need periodic lubrication, dosing the amount of oil directly onto the pin-bush contact zone at scheduled intervals. They reduce wear through constant lubrication, compared with manual lubrication, which is often irregular. They are used on large industrial drives or on lines where manual access to the chain is limited for safety reasons. For configuration the chain length and the number of lubrication points are needed. |
| Sprockets and Drive Components | Sprockets and auxiliary components compatible with the iwis chain ranges, sized to maintain the transmission ratio and minimum tooth wear. They are relevant mainly for repairs or extensions of existing lines, where compatibility with the chain already installed must be preserved. For a quotation we need the chain pitch and the number of teeth of the sprocket. |

How do we supply iwis in Romania?
Orders for iwis chains and components follow our usual supply flow from the European Union, made to order, usually within 1–4 weeks. Please send us the chain pitch, the number of links and the bush type (standard or b.dry) — only then can we confirm the availability and the exact lead time. The rest of the technical information above comes from the technical documentation of the manufacturer iwis.
The match between the pitch of iwis chains and that of chains already installed on a machine is established on the basis of the complete order code.
Frequently asked questions about iwis
What does the code of an iwis MEGAlife chain mean, for example 08B-2?
The number before the letter indicates the chain pitch according to the European standard, in this case 08B, and the digit after it shows the number of roller strands, where 1 is simplex and 2 is duplex. The MEGAlife series needs no scheduled relubrication within the intended service life, unlike a standard roller chain, which needs regular lubrication.
What is the difference between the iwis MEGAlife 08B-1 and 08B-2 chains?
Both have the same pitch, 08B, but 08B-1 has a single strand of rollers, suitable for moderate loads, while 08B-2 has two strands of rollers, practically doubling the force transmission capacity on the same shaft. The choice depends on the power to be transmitted and the space available for fitting the chain on the drive sprockets.
Do you supply iwis chains in Romania?
Yes, iwis chains are sourced strictly on request, with arrival estimated, made to order, usually at 1–4 weeks, since we do not keep this series on the shelf ready in advance. For a correct quotation we need the chain pitch, the number of roller strands and the total length required for your drive.
What advantage do iwis MEGAlife chains have over a standard chain?
MEGAlife series chains have a sintered bush and a pin with a coating, and the service life can be up to three times that of a standard roller chain, under suitable conditions. This is useful especially in installations that are difficult to access for maintenance.
