The shaft sleeve is supplied with tapped holes for dismounting the reducer as well as locking the reducer to the shaft.*

The input shaft diameter corresponds to IEC standard for motor shafts, thus simplifying standardization of V-belt pulleys and couplings. Locating shoulder provided for pulleys and couplings.

The input shaft is supplied with tapped hole for fitting V-belt pulley or locking washer for V-belt pulley.

All housing contact surfaces are fine milled thus eliminating the necessity for gaskets and possible oil leaks.

KIBO® – One of the most cost efficient dismounting methods that is available on the market, patented by us is available as a standard accessory to every Series J shaft mounted speed reducer.

Modern heat treatment of high quality gives gear wheel and pinions the hard wearing surface and tough core necessary to handle harsh duties.

Manufacturing tolerances comply to DIN and AGMA specifications. Helix angle and small modules give more teeth in mesh for smooth and quiet running.
