HERA® Stainless Steel Gear Drive

HERA Stainless Steel Gear Drives


Hub City® HERA® gear drives are a no-hassle, bolt-in replacement for worm speed reducers to deliver 90% plus efficiency and up to 2 times the torque rating. HERA delivers longer life to reduce downtime. These drives are available in all stainless versions which are great for washdown or corrosive environments.

HERA gear drives can be selected in a couple of ways. One is simply to choose by application parameters such as ratio, application torque or input horsepower and service factor. Another way is to interchange from the existing worm gear size. We have competitor interchanges available as well as the HERA Selector App on your smart phone, available from both major mobile OS providers.
