## Description

This 8mm REX™ Bore Miter Gear is able to mate with any other 2315 Series Miter Gear. A miter gear is a specific type of bevel gear. Two mating miter gears create a 1:1 ratio, and transmit power at a 90 degree angle due to the 45 degree pitch cone angle. The underneath side of this gear has been dished out to allow a thrust bearing to set the location of the gear (relative to the inside wall of an [1120 Series U-Channel](https://www.gobilda.com/1120-series-u-channel/)) and counteract the potential spreading forces in the most extreme applications. Additionally, the 32mm shelf on the back will allow a 32mm diameter component, such as [goRAIL](https://www.gobilda.com/gorail/), [goTUBE](https://www.gobilda.com/4103-series-gotube/) or a [Sonic Hub](https://www.gobilda.com/sonic-hubs/) to nest down in the cavity and fasten with [M4 socket head screws](https://www.gobilda.com/m4-socket-head-screws/).
