What are shaft collars used for?

Commonly found in power transmission applications, shaft collars are ring-shaped plastic or metal devices that clamp around a shaft. The purpose of the collar is usually to hold motor components, gear assemblies, sprockets, bearings, and other parts in place and sometimes facilitate their proper movement.

What can I use instead of shaft collar?

An alternative to setscrew collars are one and two-piece clamping collars. They use sockethead screws recessed within the collar’s circumference to create compressive forces that lock the collar in place on the shaft. There are no setscrews, so there’s no damage to the shaft.

How do I stop my shaft from slipping?

How to secure shafts?

1. Rely on press-fit bearings to fit well enough to not move.
2. Use a shaft collar with set screw right outside the bearing.
3. Use a pin through a drilled hole in the shaft.
4. Thread the ends of the shaft and use a lock nut.

What is the bore size on a shaft collar?

Bore sizes range from 3″ to 6″ and 75mm to 150mm.

How do you keep a shaft in place?

Bearing locknuts, sometimes called shaft locknuts or bearing retaining nuts, are utilized to secure bearings onto a shaft and are designed to prevent the loosening of components due to vibration and rotation. Bearing locknuts look different than traditional hex lock nuts.

What is a thrust collar?

The thrust collar allows the axial load to be transferred from the shaft to the bearing. Thrust bearings are typically used in pairs on each side of the thrust collar. Depending on the usage or application, there are many types to choose from.

How do you measure a shaft collar?

A shaft collar’s size is determined by its bore and is sized to match the shaft diameter. For example, if your shaft size is 1″ then you would want a 1″ shaft collar. To use this size chart, align the inside diameter of your shaft collar against the “zero” line on the right edge.

How do I stop my shaft from moving?

What bearing is best for axial load?

Bearings that are best able to afford axial movement are NU and N roller-contact bearings (fig. 4.10). If ball or roller-contact bearings are used as free bearings, then one of the bearing rings (usually the outer) must be attached freely (fig. 4.11).

What is the purpose of a thrust block?

A thrust block prevents separation of joints and pipe movement by transferring the resultant thrust force at a bend to the undisturbed soil behind the thrust block. The bearing strength of the soil is expressed in pounds per square foot.

What is the bore of a shaft collar?

Shaft Collar: Metric, 1 Piece Clamp, Plain Bore, 12 mm Bore Dia., 2024 Aluminum.

What are the three types of coupling?

Following are the different types of coupling:

• Rigid Coupling.
• Sleeve or muff coupling.
• Clamp or split-muff or compression coupling, and.
• Flange coupling.
• Flexible coupling.
• Bushed pin-type coupling,
• Universal coupling.
• Oldham coupling.

Should you grease a bearing?

Bearings need grease for one reason only, to reduce friction. As long as the lubricant is performing that service well, there should be no need to change it, or add more.

What is thrust collar?

Do you need thrust blocks with mechanical joints?

The use of the EBAA Iron mechanical joint restraint products and proven design procedures allows for reliable installations that effectively eliminate the need for thrust blocks. The use of the mechanical joint enables field adaptability that is not available with all joint restraint products.

What is a fastlock collar?

FastLock quick release shaft locking collars are used throughout the wire and cable industry for spool retention. The FastLock easily slides onto the spool shaft in one direction and locks in place. This quik loking functionality ensures spool retention while maximizing productivity.

What materials are the fastlocks made of?

All FastLocks are constructed from Stainless Steel . Steel versions are available upon request. This value will vary based on shaft diameter and hardness. It is recommended that customers perform their own testing on their specific shaft

What is the fastlock loking function?

This quik loking functionality ensures spool retention while maximizing productivity. To remove, simply pull on the release collar and the FastLock slides off of the shaft.
