Precision Shaft Couplings

Precision shaft couplings provide a reliable mechanical connection between rotating shafts, ensuring efficient torque transmission while accommodating angular, parallel, and axial shaft misalignment. Designed for demanding motion control applications, they help improve machine accuracy, reduce vibration, protect drivetrain components, and extend equipment life.

Micromech supplies a comprehensive range of precision couplings to suit applications from high-accuracy servo systems through to general industrial power transmission. Available coupling types include bellows couplings, disc couplings, beam couplings, jaw couplings, Oldham couplings, rigid couplings, safety couplings, and miniature couplings, allowing engineers to select the optimum solution for their machine design.

Each coupling type is engineered to address specific application requirements. Bellows and disc couplings provide zero backlash performance for precision servo systems, while jaw and Oldham couplings offer excellent vibration damping and misalignment compensation. Rigid couplings provide accurate shaft alignment where flexibility is not required, and safety couplings protect machinery from overload conditions by disconnecting the drive when preset torque limits are exceeded.

Selecting the correct coupling is essential to achieving optimum machine performance. Factors including torque capacity, shaft misalignment, torsional stiffness, rotational speed, inertia, and environmental conditions all influence coupling selection. Micromech's broad product portfolio enables machine builders to optimise performance while improving reliability and reducing maintenance requirements.

Whether used in servo-driven machinery, robotics, packaging equipment, machine tools, or general automation systems, precision shaft couplings help maximise positioning accuracy, improve drivetrain efficiency, and protect valuable motion control components.

Precision Shrink Discs

Precision shrink discs provide a reliable, backlash-free method of connecting hollow shafts to solid shafts without the need for keys, splines, pins, or interference fits. Using a friction-locking principle, shrink discs generate high clamping forces that securely transmit torque while allowing easy installation, removal, and maintenance.

Unlike traditional keyed shaft connections, shrink discs eliminate backlash and reduce stress concentrations within the shaft. This improves positioning accuracy, reduces wear, and extends the service life of connected drivetrain components. Their compact design also allows machine builders to maximise torque transmission while minimising installation space.

Designed for industrial power transmission applications, shrink discs are particularly suited to mounting hollow shaft gearboxes, conveyor drives, pulleys, rollers, sprockets, and rotary equipment. The self-centring clamping action provides excellent concentricity and reliable torque transmission even under dynamic loading conditions.

Available in a wide range of sizes and torque capacities, shrink discs support various shaft diameters and application requirements. The simple bolt-tightening installation process enables rapid assembly and disassembly without damaging shafts or hubs, reducing maintenance downtime and simplifying equipment servicing.

Micromech supplies precision shrink discs as part of a complete motion control and power transmission solution portfolio for OEMs, machine builders, and industrial automation applications throughout the UK.
