KTR Drive Couplings & Bell Housings

Made for motion, the KTR range of drive couplings offers leading brake and drive solutions. As a comprehensive power transmission range, KTR supplies couplings, brake systems, torque limiters, clamping sets, torque measuring and hydraulic components that offer advanced and precise performance.

ROTEX GS Backlash-Free Shaft Coupling

ROTEX GS from HAW is a 3-part, axial plug-in coupling that achieves backlash-free performance under high tensile pre-stress.


ROTEX Torsionally Flexible Couplings

ROTEX couplings from HAW are characterised by small dimensions, low weight and low mass moments of inertia yet transmit high torques.


BoWex Curved-Tooth Gear Couplings

BoWex Curved-tooth gear couplings from HAW are flexible shaft connections for a positive torque transmission.

Bosch Rexroth Africa brings the world’s leading hydraulics, pneumatics and automation brands to Africa!

Drive couplings for any application:

The KTR range of drive couplings are characterised by their high operational performance quality and long service life. Each coupling in this range is fit-for-purpose, and is suitable for performance in Africa’s toughest conditions.

The range can be used in various applications and is manufactured from a variety of materials ranging from steel to nylon, depending on requirements. The torque range can vary from 0.2 Nm to 582 000 Nm at high and low speeds. KTR couplings are fully machined and balanced resulting in a high standard of quality and reliability.

KTR also offers explosion-proof certification and American Petroleum Institute (API) approval on certain items in the couplings range. The range can be purchased as individual components or as complete couplings with finished bores, as well as un-bored or pilot bores.

ROTEX torsionally flexible couplings – ideal for higher loads:

In contrast to competitor flexible couplings, only intermediate members are subject to bending stress and are therefore prone to earlier wear, the flexible teeth of ROTEX® couplings are subject to pressure only. This gives the additional advantage of the individual teeth being able to accept considerably higher loads.

  • Flexible, vibration-reducing performance
  • Axial plug-in provides simplified assembly
  • Failsafe operational performance
  • Torques up to 35 000 Nm
  • Maintenance-free, easy to inspect visually
  • Standard material for spiders: T-PUR®

ROTEX GS – backlash-free coupling:

ROTEX® GS is a three-part coupling, backlash-free under pre-stress that is designed for r machine tools, automation, power transmission, medical technology and packaging technology. The different hub designs and the different Shore hardnesses offer the optimal coupling for each application in automation applications.

  • Backlash-free, vibration-reducing jaw-type coupling
  • Axial plug-in provides simplified installation and assemble
  • Maintenance-free operation
  • Electrically isolating
  • Torques from 0.2 to 5 850 Nm
  • Ambient temperatures from -50 °C to +150 °C

BoWex – the ultimate coupling for reduced wear:

The KRT BoWex curved tooth gear coupling range provides flexible shaft connections for a positive torque transmission and specifically suitable to compensate for axial, radial and angular shaft misalignment – drastically reducing wear!

  • Material combination nylon / steel
  • Compensation for shaft misalignment: axial, radial, angular
  • Axial plug-in that provides simplified assembly
  • Operating temperature range: -25 °C to +100 °C
  • Torque from 5 to 2 500 Nm

Bosch Rexroth Africa companies are trained on KTR Drive couplings:

Bosch Rexroth Africa is committed to the operational efficiency of the KTR range of drive couplings. To this end, the Group regularly attends, hosts and commissions training for its branches, distributors and resellers throughout Africa.

This training, hosted by KTR Couplings’ Sales Manager for Africa, informs and educates staff on the complete KTR range, its applications and new products. The training also informs local representatives of special instructions for certain couplings and their applications were also covered.


High-quality manufactured drive couplings:

The entire range of KTR couplings is manufactured in accordance with DIN EN ISO 9001 and DIN EN ISO 14001. KTR was one of the first drive technology companies to be certified DIN EN ISO 9001 – in 1993!

This means that you can rest assured that your KTR drive coupling will continue to operate reliably throughout the toughest operating conditions in Africa!
