FAQ

What type of lubrication is required for the CNFXS-6120E-11/G gearbox?

Sumitomo Cyclo 6000 series gearboxes typically use a specific grease or oil depending on the mounting position and operating temperature. It is critical to consult the official Sumitomo maintenance manual for the correct lubricant type and fill quantity to ensure longevity and warranty compliance.

What does the ATEX rating ‘II 2G 2D c 135degC’ signify for this gearbox’s application?

This rating indicates the unit is certified for use in hazardous areas. ‘II’ is for non-mining equipment. ‘2G’ means it is suitable for Zone 1 (high risk, gas/vapor). ‘2D’ means it is suitable for Zone 21 (high risk, dust). ‘c’ indicates protection by constructional safety. ‘135degC’ (T4) is the maximum surface temperature, preventing ignition of surrounding flammable substances.

Can the input flange on this gearbox be adapted for different motor frame sizes?

The ‘E’ in the type number denotes a specific motor adapter configuration. While some adapters can be swapped, it is essential to verify compatibility with Sumitomo’s technical documentation. Using an incorrect adapter can lead to misalignment and premature failure.
