The simplex sprocket with hub, 1/2" pitch and 19 teeth, is a power transmission component that mounts on the shaft and meshes with 1/2" pitch chains. Its integrated hub allows it to be secured with a set screw or key, depending on the equipment design. It is manufactured in SAE 1045 steel, a material that offers good wear resistance and toughness for continuous service. It is a part offered by MR, intended for replacement and assembly of drives in industrial machinery.

This item is a simplex sprocket with hub, 1/2" pitch and 19 teeth (Z19), manufactured in SAE 1045 steel. The designation Simplex sprocket 1/2" Z19 indicates that it is a single-plate sprocket with a central hub for shaft mounting. The 1/2" pitch corresponds to the chain that meshes with this sprocket, and the 19 teeth define the transmission ratio when combined with another sprocket. The hub allows the sprocket to be secured to the shaft by screw, key or both, depending on the equipment design.

Typical applications of this sprocket include chain drives in industrial machines, conveyors, elevators, mixers and power transmission equipment in general. Being 1/2" pitch and 19 teeth, it is used in medium transmission ratios, both on the drive shaft and the driven shaft. It is commonly found in replacement of equipment already running with 1/2" pitch chains, where the sprocket needs to be replaced without modifying the rest of the system.

To correctly select this sprocket, verify that the chain pitch matches the 1/2" pitch and that the number of teeth is suitable for the desired transmission ratio. The hub must have the correct shaft diameter and the fastening system compatible with the existing assembly. If the sprocket operates in an environment with high load or high speeds, take into account lubrication and alignment with the chain to avoid premature wear. Manufacturing in SAE 1045 steel allows hardening or case hardening if the service requires it.

If you need a sprocket with a different number of teeth, another pitch or a different hub size, you can ask about an equivalent or a nearby size. MR offers sprockets and chain wheels, so it is possible to request variants within the same 1/2" pitch line. To do so, send the part number MR-PINON-SIMPLE-1-2-Z19 or the full designation on WhatsApp and we will quote the option that best suits your equipment.
