Additional Technical Information
Chemical Resistance Class: 2 (These indications are not guarantees of properties)
Installation and Handling Instructions: Follow the Installing and Maintenance Instructions which are supplied with each
product delivery.
Limitations: Do not force belt on pulleys; Keep belt edges free of any installation/machine
contact; This product has not been tested according to ATEX standards
(atmospheres with explosion risk – ATEX 95 regulation or EU directive 94/9) and
therefore is subject to user’s analysis in the respective environment.
Storage
For details consult ‘Storage and handling requirements for belts and machine tapes’ or contact Habasit.
Protect belts from sunlight/UV-radiation/dust and dirt. Store spare belts in a cool and dry place and if possible in their original
packaging.

* No calculation Value
3) CLA: Coordination of the centre line-average value Ra (in the US also Arithmetical Average (AA)) to the maximum
peak to valley height Rt for surfaces manufactured by chip removal.
8) Due to high coefficient of friction of running/pulley side, the suitability for use on slider beds is limited
