10000 Series Geroler Motor, 6.10 cu in/rev, 4 Bolt SAE C-mount Mounting Flange, 2-1/4 in. Straight Keyed-shaft Shaft, 1-1/4 Code 61 Split Flange-ports Ports,

This 10000 Series Geroler motor is suitable for applications like boring, industrial uses, metal forming, port equipment, and even saw mills.

Port-wise, it uses 1-1/4 Code 61 split flange ports with a 4-bolt split flange pattern. The port type is called out as a 31.75 mm (1.250 in) diameter 4-bolt split flange with staggered ports and .4375-14 UNC-2B tapped mounting holes.

Without a case drain, the motor handles up to 300 PSI of back pressure. Once you're running continuous back pressure above that, you'll need to tie in an external case drain line. Keep that line positioned so the motor case stays full of fluid at all times or you risk running it dry internally.
