What is a bore shaft collar?

Table of Contents

Round bore shaft collars are used as stops, locators, spacers, and bearing faces for a broad range of motion control, power transmission, and mounting applications. They are suitable for use on shafts, piping and tubing, and split hubs.

What can I use instead of shaft collar?

What is a shaft collar used for?

Shaft collars, or shaft collar clamps, are used to locate, space, and secure components on a shaft by fastening axially or radially to a shaft. They are used as spacers and stroke limiters as well as retaining sprocket hubs, bearings, and shaft protectors.

What does a shaft collar look like?

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 is 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.

What is a rod collar?

A shaft collar is a simply-designed machine component composed of a plastic or metal ring fitted around a rod to act as stops, spacers, or for mounting components. The collar can be loosened or tightened around the shaft using a clamp screw or multiple screws.

How do I stop my shaft from sliding?

How to secure shafts?

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

How are shaft collars made?

They are made up of a round metal or plastic ring with a clamp screw or multiple screws. Tightening the screws makes the ring tighten or loosen around the shaft. When securely tightened, shaft collars can act as mechanical stops, hold components in place along a rod, or serve as load-bearing faces.

How do I remove a shaft collar?

To use the Shaft Collar Remover, simply hold the axle with one hand and clamp the Shaft Collar Remover around the axle next to the shaft collar. Then, pull the hand with the Shaft Collar Remover and remove the shaft collar easily.

What is collar in power screw?

Power Screw with Collar In most of power screw applications (load lifting); a collar is to be designed. The presence of collar increases the friction torque. A thrust collar bearing must be employed between the rotating and stationary members in order to carry the axial component.

What is collar in screw jack?

A rotating collar on the head of the screw has holes into which the handle, a metal bar, fits. When the handle is turned clockwise, the screw moves further out of the base, lifting the load resting on the load table.

How do you choose thrust bearings?

Tapered Roller Thrust Bearing — The angle created between the bearing axis and the line of contact between the raceway and the tapered roller determines the degree of thrust this bearing can accommodate. If this angle is greater than 45°, the bearing is better suited for axial loads.

What are the different types of shaft collars and bore sizes?

Bore sizes range from 3/8” to 3” and 8mm to 65mm. Mountable shaft collars are used to mount sensors, fixtures, and other assemblies to shaft collars or each other. They are available in three different styles including: outer diameter holes, outer diameter flats and holes, and quick release.

What is the standard size of a set screw collar?

Bore sizes range from 3/8” to 1 ½” and 11mm to 40mm. Set screw shaft collars are the most effective when used on a shaft made of a material which is softer than the set screw. Ruland set collars are furnished exclusively with forged socket set screws for greater torque capacity and improved holding power.

What is the bore size of a clamp collar?

Ruland manufactures two-piece clamp shaft collars in 1215 lead-free steel with a zinc or proprietary black oxide finish, 303 and 316 stainless steel, high-strength 2024 aluminum with or without an anodize finish, titanium, and engineered plastic. Bore sizes range from 1/8″ to 6″ and 3mm to 150mm.

What are heavy duty shaft collars made of?

Heavy duty shaft collars have a larger outer diameter, width, and screw for use in applications where the highest holding is required. They are manufactured in one- and two-piece clamp style from 1215 lead-free steel with a proprietary black oxide finish and 303 stainless steel.
