Bonfiglioli’s TA series of torque arm reducers has long set the standard for reliability and affordability in heavy industrial settings, such as quarrying and mining.  With little requirement for maintenance, the TA is also favoured where downtime must be kept to a minimum.

TA Series Design Features

The main design characteristics of the TA series are:

• High efficiency
• Quiet operation
• Gears in hardened and case-hardened steel
• Gear case from cast iron
• Paint coating as standard

TA Options

An easily-mounted backstop option extends the usability of the TA series, preventing backdriving in the case of incline conveyors.

Units are factory-filled with synthetic lubricant.

Viton oil seals are an option.
