ABOUT ESJOT

ESJOT Antriebstechnik GmbH is a midsize privately owned company specialized since over 80 years in the manufacture of sprockets, gear systems, stamped and milled products.

Esjot also manufactures OEM sprockets for major Bike Companies such as BMW KTM and more.

FRONT SPROCKETS

Highest quality steel 16 MnCR5 of OEM quality is precision cut on CNC machines. Cutting the teeth with our "DIAMOND CUT" process and case hardening of 700 HV40 (case depth of 0.4 mm) meets the highest quality requirements.

Modern milling machines guarantee a perfect fit on the drive shaft with tolerances of overall diameter and wobble remaining under 0.1 mm.

REAR SPROCKETS

Center holes are precisely cut on CNC machines with extremely low tolerances. Only special steel qualities "Qste 420" and "Qste 460" are used. Mounting holes are countersunk and cleaned.

Teeth are cut with our new special procedure "DIAMOND CUT" with tolerances of overall diameter and wobble of below 0.2 mm guarantee super smooth running.

THE ESJOT DIFFERENCE: DIAMOND CUT TECHNOLOGY

In cooperation with the University of Paderborn Germany, ESJOT Antriebstechnik GmbH has developed a new process to cut the teeth of chain driven sprockets.

"DIAMOND CUT" is an innovative manufacturing process resulting in a visibly higher sprocket quality than was ever possible on standard milled sprockets.

Special tooling guarantees a super accurate cutting surface. At the same time the material is highly condensed in the area of the teeth flanges, so that in many cases additional heat treatment is no longer necessary.

All sprockets are made from the best German steel to obtain a continued high quality product.
