TA Series Torque Arm Reducer

TA Series Torque Arm Reducer

TA series

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.

N-Eupex Pin Coupling


Due to their torsional flexibility N-EUPEX couplings offer the possibility of moving critical torsional vibrations from the operating area of the mechanical equipment in such a way that no negative effects on the drive train are to be expected.  N-EUPEX couplings are made of high-quality cast iron.  The flexible elements made of synthetic rubber (buna N) are available in different degrees of hardness for many applications.  Metal pins and flexible elements are so designed that no wear occurs when properly fitted.

N-Eupex Applications

Widely used in the whole field of mechanical engineering, as high-speed coupling on the motor side (e. g. pump, fan or compressor drives) as well as high-torque couplings for the connection of gear unit and driven machine (e. g. mills).

N-Eupex Advantages

  • Coupling to be used universally for compensating shaft misalignments
  • Maximum operational reliability, since fail-safe
  • Suitable for plug-in assembly and simplified replacement of elements in the type consisting of three parts
  • Dynamic adaptation by selection of elastomer hardness
  • Torque range from 19 Nm up to 62,000 Nm for 23 sizes and 10 different types
  • Can be used in potentially explosive atmospheres; certified acc. to 94/9/EC (ATEX 95)
  • High degree of availability of parts ex stock
