<p><strong>Other Info.</strong></p>
<p>Lock nuts are used to locate bearings and other components onto a shaft or adapter sleeve.<br />They are also used for mounting bearings on tapered shaft seats and dismounting bearings from withdrawal sleeves.</p>
<p>Lock nuts have to be secured to prevent unintentional loosening.<br />This is done, either by a locking device that engages a keyway in the shaft or key slot in the adapter sleeve, or by a locking mechanism integrated in the nut.</p>
<p>Lock nuts with an integrated locking mechanism reduce the cost of the shaft as no keyway is required.</p>
<p>Installation is also quicker and easier because no separate locking device is necessary.<br />However, the loosening torque of these lock nuts requires more attention.</p>
<p>Lock nuts are locked on the shaft (sleeve) by friction. <br />The friction, and therefore the loosening torque, varies as a result of the accuracy of the tightening torque of the grub screw (locking screws), the surface finish of the shaft (sleeve) thread, the amount of lubricant on the thread, etc. <br />The lock nuts should be properly mounted and there should be only a limited amount of lubricant on the thread.</p>
<p>Sufficient locking for intended bearing applications.<br />Full locking effect is obtained when the nut is not pressed against the locked component.</p>
<p>KMK series lock nuts have a threaded steel insert in their bore to lock the nut in place on the shaft or adapter sleeve.<br />The threads on the insert match the locknut threads.<br />The insert acts as a pressure plate when a grub screw, which runs through the body of the lock nut, is tightened.</p>
<p>Lock nuts are intended to locate radial bearings in less demanding applications.</p>
<p>They should not be used on shafts with a keyway or on adapter sleeves with a key slot.</p>
<p>The locking device can be damaged if it aligns with a keyway or slot.</p>
<p><strong>Installation and removal</strong></p>
<p>There are slots around the circumference to accommodate a hook or impact spanner.</p>
<p>All lock nuts can be reused, provided they are not damaged. A new lock washer, locking clip or locking plate should be used each time the corresponding lock nut is installed.</p>
<p>A hex-key is needed to tighten the grub screws.<br />The screws should be tightened to the torque value listed in the product tables.</p>
