Bearing Lock NutsM10 - M100

FU-SS

Features• Unique slim body design• Secure locking without keyway and tab washer• Improved shaft strength and balance• Simple infinite adjustment• Re-usable up to 100 times.• Resists vibration and shock• Equally effective for rotation in either direction even with rapid reversals• One piece construction allows simpler, quicker assembly.

Other Info.• A lead in chamfer equivalent to one thread pitch is required.• The screw thread should be to ISO 965 (Class 6g tolerance).• Lubricate the shaft before assembly or removal of the nut. With shafts of low hardness use a high performance lubricant.• To maximise effectiveness, ensure there are at least two full threads beyond the friction ring.• The squareness specified for the mating face is achieved with a tightening torque equivalent to double the prevailing torque.• Do not use a high rotational speed impact wrench.• Do not use the nuts on shafts with keyways.• Do not screw in the nut from the friction ring side.• Stop using the nut when excessive deformation or other fault is found in the friction ring and the clamp.• For severe or unusual applications please contact our Technical department.

P

P*

Construction & Function: FU-SS locknuts are one piece items where the locking function is performed by a spring peened into the top of the nut. In use, the spring bears on the flank of the shaft thread with force (P) generating reaction force (P*) in the screw threads with a resulting high friction torque (prevailing torque). The nut therefore remains locked in position.

B E A R I N G SBearing Lock Nuts

For High Precision with Locking Pins : M10 - M200Lock nuts are used to locate bearings and other components onto a shaft or adapter sleeve. They are also used for mounting bear ings on tapered shaft seats and dismounting bearings from withdrawal sleeves. Lock nuts have to be secured to prevent unintentional loosening. 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. Lock nuts with an integrated locking mechanism reduce the cost of the shaft as no keyway is required. Installation is also quicker and easier because no separate locking device is necessary. How-ever, the loosening torque of these lock nuts requires more attention.Lock nuts are locked on the shaft (sleeve) by friction which varies (with the loosening torque) as a result of the accuracy of the tightening torque of the Set screw (locking screws), the surface finish of the shaft (sleeve) thread, the amount of lubricant on the thread, etc. The lock nuts should be properly mounted and there should be only a limited amount of lubricant on the thread.There are three locking pins equally spaced around the circumference of the nut to lock it onto the shaft. The locking pins are pressed into the shaft thread with Set screws. The end face of each pin is machined to match the shaft thread. The holes for the locking pins and Set screws are drilled at an angle to the shaft thread to avoid backlash.Intended for applications where high precision, simple assembly and reliable locking are required. They should not be used on shafts with a keyway or on adapter sleeves with a key slot. The locking pin can be damaged if it aligns with a keyway or slot. M260 to M420 threads can be supplied on request, P.O.A.

Installation and removalThere are slots around the circumference to accommodate a hook or impact spanner.In addition to the slots, KMT lock nuts with a thread ≤75 mm (size ≤ 15) have two opposed flats to accommodate a spanner.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.Lock nuts are designed for frequent installation and removal.KMT lock nuts should be locked in two phases:1: Tighten the Set screws carefully until the locking pin engages the shaft thread.2: Alternately tighten the Set screws with a torque wrench until the recommended torque value is achieved.These lock nuts are adjustable. The three equally spaced locking pins enable the nut to be accurately positioned at right angles to the shaft or they can be used to adjust for misalignment between the abut ment surface and the adjacent component. Adjustments can be made using the following procedure:Loosen the Set screw at the position showing the greatest deviation; tighten the two remaining screws equally; re-tighten the screw that was loosened; check the accuracy of the installation with a dial gauge; Repeat the procedure if the result is not adequate.When removing the lock nuts, the locking pins can still engage the shaft thread even after the Set screws have been loos ened.Using a rubber hammer, tap the nut lightly in the vicinity of the pins to disengage the pins from the shaft.

They should not be used on shafts with a keyway or on adapter sleeves with a key slot. The locking pin can be damaged if it aligns with a keyway or slot.These have a full cylindrical out side surface and a different thread pitch than KMT nuts for some sizes. They are intended primarily for applications where space is limited and can be used to establish a gap type seal.

Installation and removalThere are holes around the cir cumference and in one side face, tightened with a pin wrench, a pin type face spanner or a tommy bar. 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.

B E A R I N G SBearing Lock Nuts

With an Integral Locking Device for Simple Mounting : M10 - M100Lock nuts are used to locate bearings and other components onto a shaft or adapter sleeve. They are also used for mounting bear ings on tapered shaft seats and dismounting bearings from withdrawal sleeves. Lock nuts have to be secured to prevent unintentional loosening. 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. Lock nuts with an integrated locking mechanism reduce the cost of the shaft as no keyway is required. Installation is also quicker and easier because no separate locking device is necessary.How ever, the loosening torque of these lock nuts requires more attention.Lock nuts are locked on the shaft (sleeve) by friction. The friction, and therefore the loosening torque, varies as a result of the accuracy of the tightening torque of the Set screw (locking screws), the surface finish of the shaft (sleeve) thread, the amount of lubricant on the thread, etc. The lock nuts should be properly mounted and there should be only a limited amount of lubricant on the thread.Sufficient locking for intended bearing applications.Full locking effect is obtained when the nut is not pressed against the locked component.There is a threaded steel insert in the bore to lock the nut in place on the shaft or adapter sleeve.

The threads on the insert match the locknut threads. The insert acts as a pressure plate when a Set screw, which runs through the body of the lock nut, is tightened. Lock nuts are intended to locate radial bearings in less demanding applications.They should not be used on shafts with a keyway or on adapter sleeves with a key slot. The locking device can be damaged if it aligns with a keyway or slot.Installation and removalThere are slots around the circumference to accommodate a hook or impact spanner.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.A hex-key is needed to tighten the Set screws. The screws should be tightened to the torque value listed in the product tables.
