2 - rollers torque limiter: introduc on Precise torque se ng by adjus ng the radially balanced locking nut. Innova ve calibra on system by H dimension for an immediate calibra on of the device. Equidistant re-engagement in phase or at 360. Available with electromechanical switch / proximity for the transmission disconnec on. Immediate interven on for an improved reac on compared to electronic systems. Maintenance-free for long las ng high reliability. Suitable for oily and wet environments. ON REQUEST Complete with transmission gear, fully turned and mounted (plate wheel, pulley, gear pair). Possibility to use helical springs for low interven on torques. Connec ons with bore and keyway, locking assembly possible. Version with personalized re-engagement in phase 36, 45, 60, 90, 120, possible. Safety coupling with the transmission of mo on through rollers that allow complete disengagement when the calibrated torque is reached permi ng a quick stop of the transmission due to micro-em1. Suitable for transmi ng high torque with high reliability and compact size. MAIN APPLICATIONS Packaging and wrapping machines. Labelling machines. Bo ling machines. Conveyors. ADVANTAGES AND BENEFITS Protects the gearbox from jamming due to foreign ma ers. Protects packages from squashing and deforming. Protects the product handling elements from accumula ons. Maintains the ming between driver and driven a er an overload. : Basic model. from 2,5 to Nm 120 mm bore Page / FS: suitable for the moun ng of simple transmission. from 2,5 to Nm 120 mm bore Page GTR: connec on with torsionally rigid coupling. from 2,5 to 2800 Nm 90 mm bore Page GAS: connec on with flexible coupling with high misalignments. from 2,5 to 9600 Nm 129 mm bore Page GEC: connec on with flexible coupling with reduced misalignment. from 2,5 to Nm 180 mm bore Page 28 EXAMPLE OF ASSEMBLY (or ) with organ supported by a bearing Transmission parallel sha.

3 - rollers torque limiter: models : Roller torque limiter for steady transmission with high torques and vibra ons Roller transmission. Equidistant automa c re-engagement. High torque se ngs at reduced dimensions. Same interven on torque in both direc ons. Torque range from 10 to Nm;. bore ø120 mm. /F: Roller phase torque limiter, synchronised connec on between input and output. Roller transmission. Op mized roller arrangement (patented) with perfect stability and 3 point contact. Automa c re-engagement in phase 360 or personalized (30, 45, 60, 90, 120,...) High torque se ngs with compact dimensions. Torque range from 10 to Nm;. bore ø120 mm. The safety devices ComInTec with reengements in phase are characterized by a unique distribu on of the rollers that represents the mathema cally op mal solu on to have a secure support balanced in all possible posi ons within 360. When the limiter disengages, there are always at least three equally spaced rollers that rest on the rolling surface. 23 : Ball torque limiter with op mum sensi vity in case of sudden torque varia ons (ON REQUEST) Ball transmission.

4 - rollers torque limiter: versions.../tas: Torque limiter with stop pins Complete disconnec on prevented. Minimum movement of the mobile base for an electrical signal to stop transmission. Roller or ball transmission. Torque range from 2,5 to Nm;. bore ø68 mm. Suitable for applica ons where the drive must not be disconnected. The stop pins inserted in the dentral support as shown in the figure serve to limit the axial stroke of the device, preven ng its complete disengagement and thus maintaining a stable transmission connec on..../am: Torque limiter with mechanical disconnec on to maintain the ming between driver and driven 24 SMO DX Stop pin (patented) resists 4 mes the imum torque. 345 rota on allows the cancella on of the residual torque before the device stops. Maintains the ming and re-engages in the same posi on. High torque se ngs at reduced dimensions. Torque range from 10 to Nm;. bore ø68 mm. To allow our engineers to select the correct direc on SX or DX for your applica on, we require a drawing showing: - how the unit will be mounted on to the sha (orienta on). - the direc on of rota on - confirm which drive will con nue to rotate a er the overload, - the sha or plate wheel, pulley, etc..../smo: Torque limiter with different disengagement torques from clockwise to an -clockwise rota on.
