S Series Geroler Motor, 17.90 cu in/rev, 2 Bolt Mounting Flange, 1 in. Straight Keyed Shaft, 7/8-14 St.Thd O-Ring Ports, Compact yet powerful|Extended bearing life|Increased shaft seal

At 491 newton metres of rated torque, this motor handles the kind of sustained demand that grain augers put on a drivetrain without much fuss. That torque figure puts it well within the range used for agricultural auger applications, which is one of the listed uses for this exact unit. Just make sure you run it through the recommended break-in first, about an hour at 30% of rated pressure before going to full load, and that the motor is fully primed with fluid before any load hits it. Skipping that step tends to shorten bearing life faster than anything else.

The key details on this motor are a 2 bolt mounting flange, a 1 in straight keyed shaft, and .875-14 UNF-2B SAE O-ring ports (7/8-14 straight thread O-ring). Displacement is 17.9 cu in per rev, so it matches applications like agricultural augers, harvesters, and seeders where that size motor is used.
