Solving problems in your industry

Whatever the industry or application, mayr can offer not only a wide variety of power transmission products, but also the engineering expertise to assist in the design of your drive system.

Packaging, food processing, automatic assembly equipment, and etc., all of these industries offer numerous applications for mayr's power transmission products. Especially now, with this type of machinery becoming more flexible, efficient and automated, reliability is essential, and considering the substantial investments required by their users, downtime simply cannot be tolerated. In this highly competitive market, mayr supplies many unique and versatile power transmission components and has established many long lasting relationships with satisfied customers worldwide.

Crashes in machine tools cost, on average, $12,000.00, and due to the human factor can never be completely avoided. Therefore, the only solution is to minimize the damage which occurs during a crash. mayr has developed a patented overload clutch that can disengage up to 90% of the damaging energy. This allows the machine tool manufacturer to produce a more reliable machine, requiring less maintenance and service, and the machine tool user to purchase a machine which will increase his productivity.

In a printing press, accurate registration and long lasting quality depend, to a great extent, on the rigidity of the drive components. mayr backlash free, torsionally rigid couplings have proven their performance and reliability even after years of use. A fact that has established the mayr reputation for quality products with printing press manufacturers all over the world, and has led to the development of several other mayr products currently in use in this industry.

Mechanical torque limiting clutches

EAS® mayr EAS® mechanical torque limiting clutches provide accurate, reliable overload protection for all types of machinery and equipment. With proven performance in thousands of different applications these versatile units are available in single or multiple positions, free wheeling and torque sensing models. EAS clutches also feature either manual or automatic re-engagement, and an unique method for setting the overload torque which makes adjustment both accurate and easy. With torque capacities up to 1,680,000 in-lbs. bores from 3/8 in. to 12 in. and the industries widest variety of mounting arrangements, EAS clutches can easily be adapted to meet your overload protection requirements.

EAS®-NC The mayr EAS®-NC is the state of the art in mechanical torque limiting clutches. Featuring a patented system for backlash free torque transmission, and instantaneous disengagement, the EAS-NC is ideally suited for those applications where positioning accuracy is critical, such as on machine tool feed drives. The EAS-NC is available in ten sizes, with torque capacities from 4.4 in.-lbs. to 21240 in.-lbs. and bores from 1/4 in. to 3 in.

EAS®-Sm / EAS®-Sp Today's requirements for manufacturing flexibility and increasing automation demand innovative and sophisticated power transmission components. The EAS®-Sp and EAS®-Sm are torque limiters that can take over other functions than pure preset torque limiting. As the disengaging torque of the units is controlled by air (EAS-Sp) or electromagnetic (EAS-Sm) the torque setting can be altered remotely, even while the equipment is operating. This is done simply by adjusting the voltage or air pressure to the clutch. In addition both types offer the function of an ON/OFF clutch with either single or multiple re-engagement. A control unit is available for both units, which can be interfaced with even most sophisticated control systems. The EAS-Sp/Sm units are available with torque capacities from 53 to 22144 in.-lbs.

Mechanical force limiters

EAS®-axial Torque limiting clutches alone cannot satisfy all of the requirements for overload protection. For those systems involving linear motion, the mayr EAS®-axial overload element limits axial forces. Acting as a rigid connection in normal operation, the EAS-axial overload element transmits tensile and compressive forces without backlash or play. However, once the infinitely adjustable overload force has been exceeded, the EAS-axial overload element disengages. Re-engagement is automatic, at the point of disengagement. The EAS-axial overload element is available in eight sizes, with capacities from 17 lbs. to 67,500 lbs.

All steel torsionally rigid couplings

ROBA®-D mayr ROBA®-D all steel flexible disk couplings have proven their value and reliability in the most demanding applications. Featuring unitized disk packs, exceptionally high torsional rigidities and torque capacities to 529,000 in-lbs., ROBA-D couplings compensate for parallel, angular and axial misalignments between shafts. Maintenance-free, with hubs, coupling sleeves and flanges made from the highest quality steel forgings, ROBA-D couplings are suitable for high speed applications and temperatures up to 480° F. ROBA-D couplings are also available with special length spacer sleeves for use as floating shaft couplings, and can be provided with hubs mounted using Q.D or taper lock bushings, or frictional locking devices.

ROBA®-DX The increasing number of applications utilizing servo drives has necessitated the development of a low inertia, torsionally rigid flexible coupling. The mayr ROMA -DX coupling fills these requirements. Utilizing an all steel bellows section to compensate for parallel, angular and axial misalignments between shafts, the ROBA-DX features integral frictional locking devices for a backlash free shaft/hub connection. The ROBA-DX is available in six sizes, with torque capacities to 5310 in.-lbs. and bores from 3/8 in. to 2 in.

Backlash free elastomeric couplings

ROBA®-ES The ROBA®-ES backlash free, elastomeric coupling compliments mayr's range of couplings for servo drive and backlash sensitive applications. This new concept provides an easy to assemble coupling that utilizes a special elastomeric element which eliminates many of the vibration problems encountered in today's servo systems. ROBA®-ES couplings also provide torsional rigidities high enough to meet most accuracy requirements, even though torque is transmitted through an elastomeric element. The ROBA®-ES is available in five sizes, with torque capacities to 3982 in-lbs. and bores from 1/4 in. to 1-3/4 in.

Friction type torque limiters

ROBA® slip hub The mayr ROBA® slip hub is a friction type torque limiter providing low cost, reliable overload protection. Utilizing high quality friction material and the same easy and accurate method for setting overload torque as on our EAS® clutches, the ROBA slip hub offers both long service life and trouble free operation. With torque capacities up to 442,535 ft.-lbs., bores from 3/8 in. to 7 in., and the industries widest variety of configurations, the ROBA slip hub can be used with single and multiple chain sprockets, V-belt pulleys, timing belt pulleys, gears, and etc.

Other mayr products

OPTI torque The OPTI torque is a cost effective ball-detent torque limiting clutch for low speed applications. Featuring wide torque ranges in all sizes, a positive locking arrangement to prevent torque setting changes during operation and a large diameter limit switch plate allowing the use of commercially available, inexpensive limit switches, the OPTI torque is an economical solution to accurate, reliable overload protection. The OPTI torque is available as either a single or multiple position clutch in five sizes, with torque capacities from 22 in.-lbs to 5753 in.-lbs. and bores from 3/8 in. to 2-1/8 in.
