Boston Miter Gears are designed for the transmission of motion and power between two intersecting shafts positioned at a right angle. Miter Gears are similar to Bevel Gears except Miter Gears are used for 1:1 ratios. Straight tooth Miter Gears are cut with a generated “Coniflex” tooth form providing increased life and quieter operating conditions. Spiral tooth Miter Gears are better suited for higher speeds and high torque applications. And don’t forget Boston Gear assured Same Day Shipment program – revolutionary premium free assured same day shipment for in-stock items.
