Renold's Coupling business consists of three established manufacturing companies — Renold Hi-Tec Couplings, Renold Couplings & Freewheels and Renold Ajax Couplings — who together manufacture one of the widest selections of industrial couplings supplied by any manufacturer worldwide. The Industrial Couplings range includes torsionally flexible rubber-in-compression couplings, all-metal gear couplings for maximum power capacity, soft-start fluid couplings for high-inertia machinery, and custom gear spindles for the primary metals industry.

The range covers everything from low-powered, torsionally flexible designs to heavy-duty all-metal couplings, giving plant engineers a single source for standard and customised clutch and coupling products. Used for:

• Transmitting power reliably between shafts that are misaligned or subject to shock loads
• Soft-starting high-inertia machinery with fluid couplings such as Hydrastart
• Heavy-duty mill drives using Ajax geared mill spindles and standard gear couplings
• Absorbing torsional shock and vibration with elastomeric couplings such as Spiderflex and Tyreflex

Renold Ajax Couplings has produced more than 20,000 traction couplings for subway rail cars over the past 35 years, used in cities across the US, Singapore, Malaysia, Brazil and Korea.
