Boston Gear is a global leader in manufacturing quality power transmission products. The extensive Boston Gear Products catalog includes speed reducers, gears, jaw coupling hubs and spiders, shaft collars and air regulators. Boston Gear 700 Series speed reducers feature a case-hardened alloy-steel worm & shaft design with a large oil reservoir, to provide efficient heat dissipation and lubrication. These reducers are capable of delivering torques up to 9603 inch lb and a maximum gear ratio of 60:1. Boston spur gears are designed to transmit motion and power between parallel shafts and are offered in 14.5- and 20-degree pressure angle variants. The 14.5-degree gears provide a higher contact ratio for smooth operation and also help prevent backlash errors due to centre-distance between gears.

The company also offers a variety of Boston Gear parts, such as input / output oil seals and first-reduction gear kits, for replacement of old and worn-out components. These products are available in different materials and diameters on Raptor Supplies, an authorised Boston Gear distributor.
