What is an eccentric locking collar on a bearing?

What is an eccentric locking collar on a bearing?

Eccentric locking collar mounted bearings contact the shaft over a larger surface area compared to setscrew mounted bearings. This can reduce shaft damage and fretting corrosion.

How do you lock a locking collar on a bearing?

Slip the bearing on the shaft and then put the lock on and barely tighten it by hand, the way you’re doing it. Now hold the collar and turn the shaft and inner race like the bearing was starting to sieze. If you’ve tightened opposite the rotation, the collar will loosen.

What are eccentric bearings?

Eccentric roller bearing is a very practical types in all the bearings. It has a simple structure, including an outer ring, an inner ring, rolling element and rolling element basket. The hole of inner ring is eccentric hole and there is a longitudinal keyway on the medial wall of eccentric hole.

What is a eccentric lock?

Locking Mechanisms Eccentric: Provides a collar with an eccentric lip that mates with an eccentric lip on the bearing inner ring. Turning the collar while holding the shaft and inner ring results in a “cam” action that locks the collar and inner ring to the shaft.

How does a lock collar work?

They use positive binding, which means over time, the hold becomes stronger. Since eccentric collars don’t loosen, the shaft is safe from scarring caused by loose screws. While the eccentric collar does have a larger contact area, like the setscrew, it forces the shaft to one side of the inner race.

What is a collar bearing?

Definition of collar bearing : a thrust bearing having a suitably formed face or faces that resist the axial pressure of one or more collars on a rotating shaft.

Which Loctite to use for bearings?

Loctite® Bearing Mount 609™ bonds cylindrical slip-fit or press-fit parts to prevent loosening. Excellent for keeping bearings in place in housings or on shafts.

How does a locking collar work?

The locking collar has a counterbored recess made purposely eccentric to the collar bore. When assembled on the shaft, this eccentric recess engages, or mates, with an eccentric cam end of a bearing’s inner ring. The collar is engaged on the inner cam of the bearing.

Why collar bearing is used?

Collar bearings are thrust bearing having a suitably formed face or faces that resist the axial pressure or decreases the intensity of pressure of one or more collars on a rotating shaft.

What is an eccentric locking collar bearing?

Eccentric locking collar mounted bearings contact the shaft over a larger surface area compared to setscrew mounted bearings. This can reduce shaft damage and fretting corrosion. Slide the eccentric collar against the mating end of the insert inner race.

What is the best locking mechanism for mounted ball bearing?

PTI offers all four (4) shaft locking mechanisms for mounted (aka “housed”) ball bearings: Let’s examine the second option: The Eccentric Locking Collar is a very popular locking mechanism for securing a mounted bearing to the shaft, second only to the Setscrew Locking method.

How do you install an eccentric collar on a shaft?

Slide the eccentric collar against the mating end of the insert inner race. Snug the collar on the mating eccentric in the direction of shaft rotation. Place a mild steel bar inside the hole provided by the collar and tap the collar sharply in the direction of shaft rotation and perpendicular to the shaft.

How do you install a ball bearing collar?

Snug the collar on the mating eccentric in the direction of shaft rotation. Place a mild steel bar inside the hole provided by the collar and tap the collar sharply in the direction of shaft rotation and perpendicular to the shaft. Tighten the setscrew in the collar to the proper torque (from our Mounted Ball Bearing Installation Manual ).
