How do you put a locking collar on a bearing?
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.
What is an eccentric locking collar on a bearing?
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. (Eccentric lock is not recommended for reversing rotation applications.)
What is eccentric collar?
The eccentric locking collar bearing is mainly suitable for applications where the direction of rotation is inconvenient. On one side of the inner ring of the bearing, there is an eccentric extension that cooperates with the locking ring. Remove the bearing from the shaft together with the housing.
How does an eccentric 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.
How do you remove a locking collar?
A small punch tapped against the hole to move the collar clockwise or counter c/w on the shaft should loosen it so the collar can be removed.
What does a locking collar do?
Concentric locking collars are used where setscrew locking is preferred but inner-ring stress or distortion are of major concern. These are frequently employed when space is limited and reversing shaft rotation occurs.
How does a bearing lock collar work?
How does a taper lock bearing work?
For bearings with a tapered bore, inner rings are always mounted with an interference fit. The degree of interference is determined by how far the bearing is driven up onto a tapered shaft seat or an adapter or withdrawal sleeve. As the bearing is driven up the tapered seat, its radial internal clearance is reduced.
How do you lock a shaft?
The common locking method for stepped shafts is to use a cylindrical bearing seat and an interference fit between shaft seat and bearing inner ring, and a lock nut to secure the bearing axially.
What is 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.
How do you lock a bearing to a collar?
On one side of the inner ring of the bearing, there is an eccentric extension that cooperates with the locking ring. Rotate the locking ring on the inner ring extension in the direction of rotation and tighten the hexagon socket screw on the eccentric sleeve to lock the collar and bearing to the shaft.
What’s the best way to mount an eccentric locking 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 ).
Can a eccentric collar be used for reversing a load?
*Note: this shaft attachment method is unidirectional and NOT intended for reversing loads. 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.
How do you tighten a ball bearing collar?
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 ).
