F40 Flexible Tyre Coupling Flange Half, Pilot Bore, 10 to 25 mm Bore
Available
Pilot bore flange halves for flexible tyre couplings, in sizes F40 to F200. Flexible tyre couplings join two flanges with a rubber tyre. The tyre is torsionally soft, so the coupling takes up large amounts of shock loading and backlash, and it allows for both parallel and axial misalignment. It compensates for misalignment of up to 4° angular, 6 mm parallel and 8 mm axial, and it gives torsional flexibility of up to 12° at maximum torque.
Each flange half has a pilot bore, so you can have it bored and keywayed to suit your shaft within the bore range listed for the size. The tyre is sold separately.
Where this product is used

Selecting and fitting
Choose the size from the power at the running speed, or from the torque. The rated power rises in proportion to speed, so multiply the kW at 100 rpm by the speed in rpm and divide by 100 to estimate the rating at your speed. Apply a service factor for the type of machine, and check the shaft sizes against the bore range.
Flange halves with a pilot bore. Taper lock halves are Flexible Tyre Coupling Half Flange Taperlock Bush and Flexible Tyre Coupling Half Hub Taperlock Bush.
Each coupling needs two flange halves and one tyre. Tyres are on Flexible Tyre Coupling Tyre, Synthetic and Flexible Coupling, FRAS Fire Resistant.
Isolate the drive before working on the coupling, and replace a cracked or worn tyre. Align the two shafts as closely as you can before fitting the coupling, and check the alignment again once the coupling is fitted. Good alignment gives the longest life, whatever the coupling type.
Dimensions are as listed in the manufacturer catalogue and are for reference. Contact AIMS to confirm a measurement if it is critical to your application.
