摘要： Systems and methods for preventing rotation of rotor bearings in electric motors which enable retrofitting of conventionally designed bearings to use spring-loaded keys instead of elastomeric T-rings to prevent rotation while allowing axial movement of the bearings within a stator bore. An elongated, curved spring arm is positioned in the nesting groove at the outer periphery of the bearing. One end of the spring may be secured to the bearing by positioning an S-shaped bend in the spring arm through a hole in the floor of the nesting groove. A key at the opposite end of the spring arm is urged radially outward by the spring arm. The key may be positioned in a slot in the outer portion of the bearing, and the spring arm may be retained in the groove by a retaining pin installed in the groove.
