Advanced Machine & Engineering Co. (Rockford, IL) provides its unique Spieth locknuts for accurate rotor positioning and reliable thrust bearing retention on compressors, shafts, spindles and other industrial applications, in a unique engineering achievement. Key features include a square face to thread precision, for better bearing reliability and compressor efficiency; and a lock screw adjustment that does not reduce end clearance or negatively impact reliability, says the company. The basic design of the Spieth adjustable locknut involves two axially arranged radial grooves, one from the outside and one from the inside, which result in a diaphragm-like cross-section to give the locknut a predetermined axial elasticity. The internal groove divides the locknut into a clamping and a locking section.
