Compressor Motor Rails - Sold Per Pair, NEMA 145T to 284T Electric Motors and 5 to 20 HP Engines
Motor rails for air compressors, sold per pair. These are the rails the motor or engine sits on when it is mounted to a compressor tank or base, sized to the motor frame or the engine so the bolt pattern and the height come out right.
If you are repowering a compressor, replacing a seized motor with a different frame size, or rebuilding a base that has rusted out, the rails are the part that decides whether the sheaves line up. Get the frame size right and the drive centres and belt alignment fall into place. Get it wrong and you are shimming.
Sizes

- M5511: 145T frame

Every price here is for a pair
Motor rails are always used in pairs, one under each foot line of the motor, and that is how they are supplied and priced. You do not need to order two.
Finding your frame size
The NEMA frame number is stamped on the motor nameplate, usually in a box marked FR or FRAME. It is the whole code that matters, letters included: a 184T and a 184 are not interchangeable, and the T suffix tells you it is a modern T-frame motor with the standard shaft and mounting dimensions for its size. For the common compressor motors that is 145T on 1.5 to 2 HP, 184T on 5 HP, 215T on 7.5 to 10 HP, and 256T or 284T on 15 to 25 HP, but always read the nameplate rather than working back from the horsepower.
Related parts
We also stock the motor adapter plates, sold per pair, for 10, 15 and 20 HP installations and for Kohler CH13S engines, and the belt tightener for engines or motors with slotted bases. If you are moving a compressor to a different motor or engine, those three parts usually go together.
Not sure what you need
Send us the motor nameplate frame number, or the engine model off the engine tag, along with the make and model of the compressor, and the Warthog Air Compressor Store team will confirm the rails before you order.
