The double sprocket with hub, 3/4" pitch and 45 teeth, is a power transmission sprocket sold by MR in SAE 1045 steel. It is used to transmit motion between parallel shafts by means of a 3/4" pitch chain, and its hub allows it to be mounted on the shaft with a larger support surface. It is a part of the power transmission line that MR sells, intended for replacement on industrial and agricultural equipment.

This item is a double sprocket with hub, 3/4" pitch and 45 teeth (z=45), in SAE 1045 steel. The designation Double sprocket 3/4" Z45 identifies the 3/4" pitch series and the number of teeth. The term double refers to the hub configuration, which provides two supports or reinforcements for mounting. MR sells it with dimensional control on the toothing and the hub, so that it meshes correctly with 3/4" pitch chains.

Typical applications include chain drives in agricultural machinery, conveyors, bucket elevators, mixers and material handling equipment. It is also used in low and medium speed transmission systems where a 45-tooth sprocket with a robust hub is required. As a product that MR sells, machining variants can be requested according to the equipment's needs.

To select correctly, verify that the chain pitch matches 3/4" and that the number of teeth (45) is suitable for the desired transmission ratio. Check the shaft diameter and the hub fastening system before mounting. During assembly, align the sprockets and tension the chain according to the equipment manufacturer's recommendations. Proper lubrication and precise alignment extend the life of the toothing.
