TORQUE LIMITERS - CLUTCHES

Product catalog summary

Introduction
Torque limiters are crucial mechanical components used for overload protection in kinematic chains, preferred over electronic devices due to their superior response time, reliability, and flexibility. They ensure machine safety and reduce downtime, adhering to EN ISO 13489-1 standards.

Types of Torque Limiters

Backlash Free Torque Limiter (DSS/SG): Provides high sensitivity and immediate disconnection without residual torque.
Economy Ball Torque Limiter (EDF/F): Cost-effective and suitable for dry, dusty conditions.
Ball or Roller Torque Limiter (DSS or DSR): Offers high stability and re-synchronization in various positions.
Friction Torque Limiter (DF): Simple, economical, suitable for dusty conditions, and provides silent overload protection.
Pneumatic Clutches (AP): Allows remote torque adjustment via pneumatic pressure.
Axial Force Limiter (DSA): Disengages at pre-set force by altering spring pressure.

Selection and Assembly
Torque limiters are chosen based on function, torque range, maximum bore, and speed, available in various models with specific characteristics and sensitivity levels.

Technical Specifications

DF Friction Torque Limiter: Torque range from 1 to 23000 Nm, max bore ø140 mm, suitable for parallel and in-line shaft connections.
EDF/F Mechanical Torque Limiter: Torque range from 7.5 to 1450 Nm, max bore ø55 mm, medium-high sensitivity.
DSS Mechanical Torque Limiter: Torque range from 2.5 to 2050 Nm, max bore ø68 mm, high sensitivity.
DSR Mechanical Torque Limiter: Torque range from 10 to 12000 Nm, max bore ø120 mm, medium-high sensitivity.

Applications
Used in conveyors, automotive, forming machines, agricultural, and woodworking machines, torque limiters protect motors and gearboxes from accidental collisions and absorb static torques without disengaging.

Advantages

Long product life and continuous reliability.
Optimum protection against environmental conditions.
Simple mounting and easy adjustment.
Highly accurate and fast machine protection.
Competitive pricing with certified quality.
