An XH Pitch Timing Pulley is designed for heavy-duty applications. In engineering, pitch refers to the distance between the teeth of a gear mechanism. The timing pulley
operates in transmission systems that need to maintain speed ratio. The pulley is also designed with trapezoidal groves where the spacing, or pitch is based on inch measurements. XH Pitch Timing Pulleys have a belt pitch of 0.875 inches. Metal and plastic are the primary materials of choice for most manufacturers of pitch timing pulleys. However, in some cases, you will find a combination of the two.The XH Pitch Timing Pulley comes with set screws and hub clamping screws
to facilitate proper mounting. The former helps tighten the pulley into a shaft while the latter keeps the hub tightly attached around the shaft. You may still find pitch timing pulleys with no hubs where you press the piece or stick it to a pole.Get the best selection of XH pitch timing pulleys at MRO Supply.Talk to us if you need any assistance.
