Boston Gear 200 Series Optimount combines the unique benefits of a shaft mount gear drive but also the flexibility of a base mounted reducer. Because of its precision machined external surfaces, the 200 Series can be integrated directly into an OEM piece of equipment or, with the addition of an output shaft kit and horizontal/vertical base, be converted to a parallel shaft base mounted gear drive. And don’t forget Reducer Express! Boston Gear revolutionary premium free guaranteed shipment program.

Excellent customer service
The couplings are just what they are supposed to be. But I wanted to comment on MRO. This was my first order with them and I was extremely surprised at how well the company is run. I will be doing more business with them in the future.

I ordered this part hoping it would arrive within 2 weeks because I had an emergency situation with an employee waiting to repair a piece of equipment at a customer’s location. The part actually arrived halfway across the country in 5 days including the weekend. MRO processed, packaged and shipped it with incredible speed. Thanks again!
