KTR: Precision Couplings and Power Transmission Solutions

KTR Systems GmbH, headquartered in Rheine, Germany, is a global leader in the design and manufacture of power transmission couplings, clamping sets, torque limiters, and brake systems. Founded in 1959, KTR has grown to employ over 1,500 people with 18 manufacturing and sales locations worldwide. The company's engineering philosophy centers on connecting rotating equipment reliably—from small servo motors to massive industrial drives.

KTR couplings connect motors to gearboxes, pumps, compressors, fans, and every other type of driven equipment in industrial facilities worldwide. Their products compensate for shaft misalignment, dampen vibration, protect against overload, and transmit torque with minimal losses. In Saudi Arabia, KTR couplings are found in virtually every industrial plant—connecting the thousands of motor-driven systems that keep refineries, petrochemical plants, and manufacturing facilities running.

KTR Products Available Through RAZZ Middle East

Flexible Couplings

The ROTEX jaw coupling is KTR's most popular product—a fail-safe, maintenance-free coupling available in 16 sizes covering torques from 2 to 13,200 Nm. Spider elements in different shore hardnesses (92-98 Shore A) allow tuning for specific vibration damping requirements. The BoWex curved-tooth gear coupling handles high torques (up to 1,700,000 Nm) and speeds for turbomachinery, compressor, and heavy pump applications common in Saudi oil and gas.

The POLY-NORM coupling series provides torsionally flexible connections for pump drives, with the unique advantage of allowing spider replacement without moving the connected machines. RADEX-N all-steel couplings serve high-performance applications requiring zero backlash and high torsional stiffness.

Torque Limiters and Overload Protection

SYNTEX torque limiters protect expensive gearboxes and driven equipment from overload damage. When torque exceeds the set threshold, the coupling disengages instantly, preventing mechanical failure. Available with automatic re-engagement or manual reset, these units protect conveyor drives, bottling lines, and production machinery across Saudi manufacturing.

Brake Systems

KTR KTR-STOP electromagnetic and hydraulic brake systems provide holding and emergency braking for hoists, cranes, and material handling equipment. Available as disc brakes, caliper brakes, and motor-mounted brakes, they serve safety-critical applications in Saudi industrial and construction operations.

Clamping Sets and Shrink Discs

CLAMPEX clamping sets provide keyless shaft-hub connections that transmit full torque without keyways, fretting, or stress concentration. Easier to install and remove than keyed connections, they simplify maintenance on Saudi industrial equipment. Available from 6mm to 800mm shaft diameters.

KTR in Saudi Arabia

KTR couplings are standard components across Saudi industrial infrastructure. Aramco pump stations use BoWex and ROTEX couplings to connect motors to centrifugal pumps. SABIC petrochemical plants deploy KTR couplings on compressors, fans, and processing equipment. SEC power plants use KTR high-speed couplings on generator and turbine connections. Saudi water desalination plants rely on KTR couplings for high-pressure pump drives.

Frequently Asked Questions

What KTR couplings are most commonly available?

ROTEX jaw couplings (sizes 14–125), POLY-NORM pump couplings, and BoWex gear couplings in standard sizes are our highest-turnover items.

Can RAZZ help select the right coupling?

Yes. Provide motor power, speed, driven equipment type, and any special conditions (high temperature, corrosive environment). We'll recommend the optimal KTR coupling type and size.

Does RAZZ supply KTR replacement spiders?

Yes. Replacement spider elements for ROTEX and POLY-NORM couplings are stocked in all shore hardnesses and common sizes for quick turnaround.

What savings do you offer on KTR products?

Standard KTR couplings show 15–25% savings versus local Saudi pricing with additional discounts on volume orders.
