Shaft Couplings

We stock a wide range of attractively priced couplings in pilot-bore or tapered-bore styles (with tapered bushes to suit). New for 2013 is a full range of grid, gear and disk couplings. e-mail for details.

In addition to this we now offer the complete KTR range. Enquire here.

Tyre Couplings

Tyre couplings consist of 2 cast iron flanges which are mounted on the shafts by means of taper lock bushes. Between them sits a flexible rubber tyre which can accomodate high angular misalignment (up to 4 degrees) without imposing undue loads on the adjacent bearings, while simultaneously absorbing shock loads and vibration in the powertrain.

Tyre couplings are easy to fit and replace, and can be visually inspected during regular maintenance. Stock sizes from 20mm to 90mm shaft.

Jaw Couplings


Low cost, general purpose couplings for most applications. Jaw couplings can accomodate small misalignments (<1 deg). parallel misalignment (<0.38mm) and iwth the nitrile insert are suitable for operations between -40C to 100C. Usually supplied with pilot bore only,

Stock sizes from 35 to 150 to suit shafts up to 60mm.

 HRC Couplings


"HRC" is a registered trademark of the Fenner Group, but has beome a widely used, generic term, to describe this coupling type.

HRC couplings consist of 2 cast-iron halves attached to shafts by means of taper lock bushes. Between these two halves is a rubber "spider" that servers as a ahock absorber and allows for a limited mis-alignment. Can be used on taper sleeves to 90mm bore or 130mm if bored through with keyway.

 Rigid Couplings

Taper lock rigid couplings consist of a fully machined male and female flange. The male can have the taper lock bush fitted from the hub side (design H) or from the flange side (design F). The female is always machined to design F. Thus an HF or FF coupling can be specified - a decision based on ease of access during fitting. (but when connecting vertical shafts use FF only).

Rigid couplings provide a convenient method of connecting 2 shaft ends, but cannot allow for any misalignment. Stock sizes to suit shafts to 125mm.

Grid couplings 


Taper grid couplings can accomodate relatively large shaft misalignments (in parallel and angular directions) as well as end float. Being torsionally flexible they have the ability to smooth out vibration and shock loading.

New for 2013 NBC is to import a range of grid couplings with horizontal or vertical splits which have a proven international track record and are fully interchangeable with other major brands.
