Bearing Lock Nut:
Material
Nut Body: Low Carbon Steel
Locking Insert: Stainless Steel Hardness HB 201-269
Other Info.
Construction Function: The lock nut comprises a nut and a friction ring (special spring). The friction ring is united to the top face of the nut by caulking. A stress P is produced by the spring effect if the friction ring contacts a screw thread as shown in the diagram (above). The P and its reaction force P* press the screw threads strongly to produce a frictional torque (prevailing torque) preventing the turning of the screw, generating an excellent looking effect.
SS Series available as standard. SC (High Carbon) & SUS (Stainless) Series available P. O. A.: Bolt threads must be equivalent to ISO 965 Medium Quality. Top of bolt thread (first 1 pitch) must be chamfered
Do not attach to a shaft with a keyway. Use lubricating oil for insulating. The crimping mount must not be hit or excessively forced. Subject to dimensional change for improvement Tighten the nut so that, at least, two external screw threads shall appear above the friction ring.
Keyways not required: Reduction of designing process No scribing process required No trimming process required No material handling process
Washers not required: Elimination of deviation in flatness, hardness and dimensions
Elimination of tightening torque deviations Elimination of failures due to the neglect of bending the tongue of the washer Less tightening time Easy assembly and disassembly
Improved shaft performance: Improvement of rotation balance (elimination of deflection). Increased shaft and external thread strength Hollow shafts eligible
Improved Accuracy: Accuracy of nut threads: ISO 965 Medium Quality (JIS Class 2) Elimination of Backlash (play).
