Shaft Collars: Application Training

Want to learn a little more about Shaft Collars?

View the following presentation outlining the different shaft collar types, materials used, and applications shaft collars are commonly found in.

What is a Shaft Collar?

Shaft collars have extremely diverse applications. Shaft collars are used on applications from holding up a flag on a flag pole, to positioning devices on medical equipment to the more common industrial applications of holding other shaft components such as bearings, sprockets and pulleys in place. In general, shaft collar applications fall into one of three broad categories:  Continue reading “What is a Shaft Collar?”

What type of shaft collars does Climax manufacturer?

Climax manufactures set screw collars and clamping collars. We also customize dimensions, add keyways, offer balanced collars, provide specialized plating, and manufacture from a variety of materials.

Set Screw Collars are the most commonly used and cost effective shaft collars. The holding power of a set screw collar is provided by the impingement of the screw into the shaft. Lightweight styles are available Continue reading “What type of shaft collars does Climax manufacturer?”

What is the industry standard for a shaft collar?

While there is no formal industry standard for shaft collars, the dimensions of most manufacturers’ collars are fairly uniform. In most applications, the shaft collar bore (ID) is considered a critical dimension while other dimensions such as outer dimension and width are considered non-critical. Dimensions for Climax shaft collars can be found on our website and in paper format. For shaft collars needing special dimensions contact our customer service department at 1-800-542-6552.

Why does a one-piece collar have a relief cut?

The relief cut removes some of the rigidity of a one-piece clamping collar to allow the screws to clamp more evenly and securely. A relief cut is important only on smaller bore collars because of the ratio of the screw to the collar material – the screw provides much of the clamp load. Climax puts a relief cut in collars with a 1 ½” bore or smaller. Relief cuts can be found on metric collars 19 mm and smaller and on our threaded collars sizes under 1 ¾-16 in.

Why do clamping collars have face grooves?

The face groove on clamping collars indicates the face that should be placed against a bearing or other component requiring a perpendicular to bore orientation. For two-piece clamping collars, the face groove also helps keep the two halves of the collar properly oriented during installation.

Can a Climax Shaft Collar be welded?

Shaft collars can be welded with some exceptions. Mild steel and stainless steel materials contain sulfur and other additives which allow for welding. However, the lowest possible current and adequate ventilation should be employed. Be sure to remove screws before welding. However, in no cases should collars with zinc plating be welded. The welding process on a zinc plated product will produce noxious fumes. Welding can be done safely on a black oxide finished product. Extreme caution is recommended when welding imported collars because of the inconsistency of the material and finishes.

What is axial holding power?

The primary purpose of a shaft collar is to resist an axial load. That is to hold itself in place despite pressure along the axis of a shaft. The axial holding power is primarily a function of screw size and applied torque. However, other factors such as presence of oil, temperature, and the finish and hardness of the shaft can impact the holding power.
