HRC70 Coupling Flange Half, Type B, Pilot Bore, 32 mm Max Bore
Available
Type B flange halves for HRC couplings, with a pilot bore, in sizes HRC70 to HRC280. The HRC coupling is made of two cast iron flanges and a rubber element that works in compression. The modular design makes fitting simple and maintenance easy, and the rubber element absorbs shock loading. Nitrile rubber and polyurethane elements are stocked to suit all stocked sizes, and the flanges come in pilot bore and taper lock versions.
Each type B half has a pilot bore, so you can have it bored and keywayed to suit your shaft up to the maximum bore listed for the size. Each listing is one flange half. The element and the other half are sold separately.

Selecting and fitting
Choose the size from the torque and the shaft sizes, and apply a service factor for the type of machine. A complete coupling needs two flange halves and one element. The halves can be paired as BB, BH, BF and so on, and the F and H halves share the same assembled length with each other.
Elements are on HRC Coupling Element, Nitrile Rubber and HRC Coupling Element, Polyurethane.
Other halves are on HRC Coupling Half, Flange Taper Lock Type F and HRC Coupling Half, Hub Taper Lock Type H.
Isolate the drive before working on the coupling. 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.
