Browning 100UR30 Right Angle Speed Reducer 30:1 Ratio, 0.14 HP Input, 120 in-lb Output, with Pulley and Sprocket

This is a Browning 100UR30 fractional horsepower speed reducer gearbox built by Browning Manufacturing, a division of Emerson Power Transmission Corp. in Maysville, Kentucky. The nameplate rates the unit at a 30:1 reduction ratio with .14 input horsepower and 120 in-lbs of output torque.

A speed reducer of this size takes a higher input speed from a small motor or a belt or chain drive and delivers a slower, higher torque output. Units in this range are typically found on light conveyors, packaging and bottling lines, indexing and feed mechanisms, and other small machinery where a compact enclosed gear drive is needed. Maintenance departments and machine builders use them as replacements when rebuilding or servicing existing equipment.

In the Browning part number, the trailing 30 matches the 30:1 ratio shown on the nameplate. Browning and Morse were both Emerson Power Transmission brands based in Maysville, Kentucky, and Browning is now part of Regal Rexnord. Buyers matching an existing installation should compare the part number, ratio, torque rating, shaft sizes and mounting pattern against the unit being replaced.
