Simplex Sprockets with Induction Hardened Teeth (45 to 55 Rc)

Due to an increasing demand for items with hardened teeth Cross+Morse is extending its range of simplex pilot bore sprockets for 3/8, 1/2, 5/8, 3/4 & 1” pitch to include a hardened tooth option.

We now offer a Standard Stock Range of Pilot Bore Sprocket in C45 with Induction Harden teeth which have the same dimensions as the Standard pilot bore range. These sprockets can be machined to suit a customer’s own requirements.

Cross+Morse is also offering a range of simplex pilot bore sprockets to include items with special features such as bore with H7 tolerance, UNI keyways and set screws for locking.

The teeth on these items are Induction Harden 45 to 55 Rc and the keyway is located on the centre line of the tooth.

Why use Hardened-tooth sprockets?

As the chain contacts the sprocket, frictional wear of the tooth and sprocket occurs. With each rotation, every sprocket tooth contacts the chain. The hardness of the tooth directly relates to sprocket life. A sprocket with a “hardened tooth” may last three times longer than a softer sprocket.

Induction hardening only hardens the area near the applicator coil which means that sprockets and gears will have hard teeth and not hard bores.
