Max hp @ 100 rpm: 455  Max Torque: 287,657 lbf.ins

Crown Pin

An established pin/buffer coupling, offering extended power capacity where the demand for long life and simplicity of construction make it suitable for working in arduous conditions.

Max hp @ 100 rpm: 3501  Max Torque: 2,207,439 lbf.ins

Tyreflex

A range of highly flexible couplings offering excellent misalignment capacity and suitable to absorb both shock loads and vibrations.

Max hp @ 100 rpm: 88  Max Torque: 55,495 lbf.ins

Discflex

A general purpose, fail safe, torsionally flexible coupling offering the option of either urethane or reinforced rubber disc as the flexible element.

Max hp @ 100 rpm: 60  Max Torque: 38,041 lbf.ins

Chainflex

An all metal flexible yet torsionally stiff coupling, suitable for use in arduous working conditions

Rigid

Rigid all metal medium/high power coupling for a non-flexible, positive connection.

Max Bore Size: 11 in.

Gearflex

Heavy duty all metal couplings giving maximum power capacity within minimum space envelope and excellent misalignment capacity.

Max hp @ 100 rpm: 67,700  Max Torque: 42,015,697 lbf.ins

Hydrastart

A fluid coupling suitable for soft starting high inertia machinery with reduced current demand, controlled acceleration and torque with drive overload protection.

Max hp @ 1500 rpm: 804 Max Speed: 3,500 rpm

PM

Heavy duty steel coupling for torques up to 53,106,000 lbf.ins. Designed for use in high shock load applications such as steel mills, quarries, grinding mills or where vibration can be a problem, ie VF drives

RB

General purpose, cost effective range which is manufactured in SG iron for torques up to 362,800 lbf.ins. The RB provides shock load damping and vibration control for less arduous applications than those requiring the PM range.

Universal Joint Assemblies

Renold Ajax offers a full line of universal joints assemblies from 4 to 30+ inch diameters, with misalignment capabilities of up to 30 degrees. Renold offers both Metric and English designs with standard slip centre sections, or special long travel assemblies are also available. Extensive stock of standard components permits same day shipment for many designs if required.

 Pin & Bush Coupling

Simple and virtually indestructible, the pin and bush design is ideal for applications that involve safety, such as elevator drives or fire pumps. The fail-safe aspect of the design allows the coupling to be serviced at convenient intervals, should the elastomer become damaged.

Geared Mill Spindles

Renold Ajax has been supplying spindles for rolling mill applications for over 50 years and offers full service and technical support for our custom engineered spindles.
