The Double Sprocket 3/4" Z19 is a hub-type double sprocket designed for power transmission setups that use 3/4" pitch chain. Its hub mounts on the shaft and is secured with screws or a key, depending on the equipment, which simplifies assembly and replacement. It is commonly found in production lines, conveyors and agricultural or industrial machinery.

This sprocket is machined from SAE 1045 carbon steel, a material known for good machinability and strength in general-purpose sprocket applications. The designation Double Sprocket 3/4" Z19 tells you the key details: 3/4" chain pitch, 19 teeth and a double configuration with a central hub that sits on the shaft and is fastened with screws or a key. The part number to reference is MR-PINON-DOBLE-3-4-Z19.

Typical uses for a 3/4" pitch sprocket with 19 teeth include chain conveyors, bucket elevators, mixers, packaging equipment and agricultural machinery operating at medium speed and moderate load. It also serves as a replacement in existing drives where the 3/4" pitch is already set and a double hub sprocket must be changed due to wear or a revised transmission ratio.

When selecting this sprocket, confirm the chain pitch is 3/4" and the tooth count matches your required ratio. Check the shaft diameter and the hub fastening method, and verify alignment between sprockets to prevent uneven wear. During installation, lubricate the chain and set the tension correctly; an overly tight chain increases wear on both teeth and bearings.

If you need a different tooth count or a single sprocket instead of a double, send the part number MR-PINON-DOBLE-3-4-Z19 or the full designation by WhatsApp. Our team can also help you determine the right pitch and hub type if you provide a photo or sketch of the equipment.

MR Industrial Accessories LLC manufactures this sprocket and supplies power transmission components, including ANSI chains, pulleys, split plummer block housings and bearings.
