Auto Chain Ever-Power Items manufactures shims for all sorts of electrical motors, both large and small. Based on the NEMA frame, Ever-Power offers standard 2” X 2” up to 5” X 5” shims, or can produce custom made shims for bigger or special motor applications. Some of these motors include Westinghouse, WEG, Baldor, Mitsubishi, Waukesha and Caterpillar. Shims are accustomed to properly align the motor to a pump or other application, to prevent bearing and coupling failing due to vibration. Having great shaft alignment is key to having equipment run smoothly and extend their existence.
