FTT-type chain guide for double roller chains in accordance with DIN 8187
Chain guides made from ROBALON and ROBATEC materials provide a guide for roller chains and offer chain-wear-reducing and maintenance-free operation for drives and conveyors.
- Low coefficient of friction – low power consumption saves energy
- Self-lubricating – no need to apply oil
- High wear resistance
- Offers chain protection – increases the service life of the chains
- High level of resistance to acids, bases, and organic solvents
- Quiet operation
- Shock and breakproof from -200°C to +80°C
- Hydrolysis resistance
- Easy to clean – ROBALON has dirt-repelling characteristics
- UV-resistant (ROBALON-S, ROBALON-E, ROBALON-GL)
- Food-safe (ROBALON-W)

Plastic guides have a high thermal expansion coefficient; this means that steel C profiles are often used so that the guides have the optimum conditions for expansion within the C profile.
As a rule, thermal expansion of 1.8 mm per 10-degree temperature difference for every 1 m of length must be assumed with Robalon.
In the event of excessive temperature fluctuations, we recommend increasing the number of expansion joints and placing them at a 45° angle to the running direction.
The maximum length of the chain guides is 10 m.
For small orders we recommend shorter lengths of 2 to 3 m to keep transport costs down.
Standard chain guides can be found in our PDF brochure. We can also produce bespoke guide profiles on request; our profile milling machines use up to 9 tools simultaneously for efficient and economical production of 1 to 1,000 rm profiles. Simply send us a drawing of your personal requirements in PDF or DWG format.
