TECO MOTOVARIO PBH Series, Instructions For Installation, Use And Maintenance Manual, Page: 10 / 56

4. TECHNICAL INFORMATION
4.1 PRODUCT DESCRIPTION
The unit has been designed to be used in specific applications and, to satisfy particular requirements, it may be supplied
in several mounting arrangements and configurations, including accessories and optional variants.
The user is responsible for using it appropriately and in line with the warnings given in this manual and the instructions on
the product identification labels.
4.2 CRITICAL APPLICATIONS
The performance specified in the catalogue corresponds to position B3 or similar. For different mounting positions and/or
particular input speeds, refer to the tables that highlight any critical situations for each size of the unit. Also bear in mind
the following applications, and contact MOTOVARIO TECHNICAL SERVICE for further information:
Use in conditions which could lead to injury if the unit fails;
Applications with especially high inertia;
Applications with high dynamic loading of the unit casing;
Use in conditions with T° lower than -5°C or higher than 40°C;
Use in environment with presence of aggressive chemical agents;
Use in a salty environment;
Mounting positions not provided by the catalogue;
Use in a radioactive environment;
Use in ambient with pressure other than the atmospheric one;
Applications providing immersion, even partial, of the unit;
Use as multiplier.
Note: The maximum torque bearable by the unit can get twice the Mn2 stated on the label, but only intended for
momentary, non-repetitive overload due to starting at full load, braking, impacts and other dynamic causes.
The value of maximum input speed n
1
max shown in the table reflects continuous duty S1 (operation under steady loading
for a period long enough to achieve thermal balance) and B3 mounting position.
Continuous speeds above 1800 rpm are nevertheless not recommended since they could cause overheating and early
deterioration of seals, bearings and lubricant.
Mounting positions other than B3 could make it necessary to use dedicated pressure-fed lubrication systems, while the
transmission ratio could in some cases originate a further limitation of the permissible maximum input speed n
1
max,
