Ball to Roller 1800 RPM or Below
Roller bearings have the capability to handle higher radial loads than ball
bearings, but must have high minimum radial loads to operate correctly.
Roller bearings must only be used in heavy belted loads, they are not
suitable for coupled loads. Because of the heavy overhung loads, most
stock motors 440 frames and smaller are not suitable for roller bearing
conversion. Only the stock 5000 frame TEFC motors with “²” shafts
have high strength steel shafts. Conversion may be performed on these
in the Kings Mountain Plant (not FSM Mod Express Center). Contact
Baldor for Freight charges to the plant for these motors.
Also see the main catalog section for motors that Baldor stocks with
roller bearings already installed. These stock motors are
identified with a
“TR” suffix after the catalog number (ECP4408TR-4).
Does Not Apply to Explosion-Proof Motors or designs that must be
built as custom motors.
