The double sprocket 3/4" Z39 is a chain sprocket supplied by MR Accesorios Industriales, designed to transmit motion in 3/4" pitch chains. Its double-row design with hub allows mounting on shafts and coupling to single or double chains depending on the gearbox configuration. It is used in agricultural machinery, conveyors and transmission equipment that demand robustness and durability.

This double sprocket with hub has a 3/4" pitch and 39 teeth (z=39). It is manufactured in SAE 1045 steel, a material with good machinability and wear resistance. The central hub facilitates mounting on shafts and fastening with a key or set screw. As it is supplied by MR, tolerances and heat treatment are guaranteed to ensure smooth engagement with the chain.

It is used in 3/4" pitch chain drives in equipment such as seeders, harvesters, grain elevators, conveyor belts and industrial machines in general. It is commonly found in gearboxes and transmission cases that require two rows of teeth to double the drive capacity or to synchronize two chains on the same shaft.

To select the correct sprocket, check the chain pitch (3/4"), the number of teeth (39) and the shaft diameter where it will be mounted. The hub must match the shaft diameter and the fastening system (keyway, set screw or taper bushing). If you need to modify the hub diameter or the number of teeth, contact us: we can source a special size.
