This unit is designed to be similar to the 800 series while meeting custom specifications. It retains the low backlash, stair step resistant gearbox design of the 800 series as well as its stiff high load capacity frame. However, the frame is highly modified in order to meet the customer's requirements. It also includes a special mount for holding and counter balancing the customer's load. The unit is supplied with the clean room option that includes electroless nickel plating on all steel parts, stainless steel hardware, including the caster frames, and high gloss epoxy white paint on the gearbox housing.
