Bonfiglioli product lines

Who Bonfiglioli is

Bonfiglioli is an Italian manufacturer of power transmission and drive products, headquartered in Calderara di Reno on the edge of Bologna. Its range runs from industrial gearmotors and worm gearboxes through precision planetary gearboxes and servomotors to inverters and servo drives, and drives for mobile machinery and renewable energy. For motion control engineers the relevant part is the Motion & Robotics range: precision planetary gearboxes, BMD servomotors and drives. Bonfiglioli is a trademark of its owner.

The company reports about 5,000 employees, 24 commercial sites and 18 production sites, and a network of about 550 distributors in about 80 countries. It describes three markets: industrial automation, mobile machinery and renewable energy.

History and ownership

Bonfiglioli dates its foundation to 27 August 1956, and the company marked its 70th anniversary in 2026 with an open day at the Calderara di Reno headquarters. Its own anniversary pages describe the VF worm gearbox as its first product and trace a path from robust gearboxes to integrated mechatronic solutions. A mural at headquarters records the company’s patents from 1959 onwards. The head office street, Via Cav. Clementino Bonfiglioli, and the roundabout outside the Forlì plant carry the name of Clementino Bonfiglioli.

The legal entity is Bonfiglioli S.p.A., registered in Calderara di Reno. The anniversary pages name Sonia Bonfiglioli as Executive Chairwoman and describe a strong family culture; the website pages we read do not give a shareholding breakdown. Production sites include Forlì in Italy and Hattingen in Germany, among others.

Product portfolio

Precision planetary gearboxes

The TQ series is the high-performance in-line range: sizes 060 to 160, nominal output torque up to 800 Nm, ratios 3:1 to 100:1, backlash under 2 arcmin in one stage and IP65. The TQK is the right-angle version with the same torque range, and the TQF has a flange output for pinions and rotary loads, with backlash of 3 to 7 arcmin.

The LC series is the effective-line in-line range in sizes 050 to 155, nominal torque up to 450 Nm, backlash under 6 arcmin in one stage and IP54. The MP series covers 12 to 1,000 Nm nominal with backlash of 10 to 17 arcmin for less demanding servo axes, and LCK and KR add right-angle options. Our gearbox hub and the harmonic vs planetary vs cycloidal guide help match backlash class to the application.

Servomotors

The BMD servomotors are permanent-magnet AC servomotors in six sizes from 65 to 170, with stall torques from 0.85 to 45 Nm and rated speeds up to 6,000 rpm. They are rated IP65 (IP67 optional) and offer resolver, EnDat, Hiperface, SinCos and inductive feedback options. See our servo and stepper motors hub.

Inverters and servo drives

AxiaVert is a compact inverter and servo drive family from 0.25 to 15 kW at 400 V, with CANopen, EtherCAT, PROFINET or PROFIBUS and STO and SBC to SIL 3 / PL e as standard. The ANG and Active Cube families extend to 400 kW (1,200 kW in parallel). Our servo drives hub explains how drive, motor and feedback are matched.

Technologies and standards

Bonfiglioli publishes nominal output torque, torsional backlash, torsional stiffness and maximum radial force for its precision gearboxes, which are the figures to compare when choosing between ranges: for example, 4.8 to 170 Nm/arcmin stiffness and up to 15,000 N radial force on the TQ. Food-grade lubrication is offered on the TQ. On the drive side, Safe Torque Off and Safe Brake Control to SIL 3 / PL e are built into AxiaVert, with further safety functions on higher variants.

Industries served

The precision ranges target industrial automation: packaging and food machinery, handling, robotics and machine tools. The wider group serves mobile machinery and renewable energy, with ranges such as slew drives, so much of its planetary gearing is designed for heavy outdoor duty.

Global and UK presence

Bonfiglioli lists commercial companies in many countries and a distributor network of about 550. In the UK, Bonfiglioli UK Limited is at Unit 1 Calver Quay, Calver Road, Warrington, Cheshire WA2 8UD, telephone +44 1925 852 667. UK engineers can buy direct from the UK company or through its distributors; an online shop is also offered for some products.

What to have ready for a Bonfiglioli enquiry

Give the full product code from the nameplate (series, size, ratio, backlash class, input adapter and output), plus the motor make and model the gearbox is fitted to. Add output torque and speed, duty cycle, mounting position, radial and axial loads, and any food-grade requirement. For drives, give supply voltage, motor data, feedback type and fieldbus.

Sourcing Bonfiglioli parts through Specify Motion

Specify Motion is independent of Bonfiglioli and is not affiliated with it. We can help source Bonfiglioli gearboxes, servomotors and drives for an existing machine, or propose equivalents from our supply network that meet the same published figures. Find a replacement takes the product code and the requirement.
