Through Bore

Back Side Offset: The width from the center of the pulley to the backside edge of the hub or bore adapter.
Fits with Bearing: The size of the bearing the bore adapter is designed to fit into. Phoenix bore adapters are available for 5/8" and 17mm bearings.
Frontside Offset: The width from the center of the product to the front edge of the hub, bearing, or bore adapter.
Inside Diameter: The distance across the center hole, or bore, of the product. This dimension should match the diameter of your shaft or bolt.
Material: Describes what the product is made from. Plastic, aluminum, and diecast are softer, lighter, and do not rust. Steel and cast iron are meant for heavy-duty applications, but can rust in certain circumstances.
Outside Diameter: The distance across the circle of the product, from outside edge to outside edge.
Shoulder Length: The size of the shoulder on the bore adapter. When assembled into a bearing, this is the distance from the edge of the bearing to the edge of the bore adapter. Some bore adapters do not have a shoulder length. These are known as "sleeves" because they match the width of the bearing.
Throughbore: Length of the bore, from one edge to the other. The Frontside Offset and Backside offset together equal the length of the throughbore.

We recommend selecting your bore adapter on the page with the idler pulley you intend to purchase. Choose from the drop-down menu and we have calculated how far the bore adapter you select will stick out from the outside edge of your pulley - so you know if you've made the best choice. We are happy to install bore adapters at no additional charge.
