How Do Abrasive Sanding Drums Work?

Abrasive sanding drums are used to mount an abrasive sanding sleeve. The rubber drum expands to hold the sanding sleeve in place. Sleeves are secured on the drum by controlled expansion of the solid rubber drum spindle. The rubber provides a cushioned backing to assure a smooth, even finish during use. Always remember to use recommended safety equipment when working with hand and power tools.

What materials are used in manufacturing Climax rigid couplings?

Steel Couplings are the most commonly used and manufactured. The exact type of steel used varies depending on the machine process but generally low-carbon steel is used, including materials such as 1215, 1045, and 1026.

Stainless Steel Couplings are used primarily in applications (more…)

What finishes does Climax offer on rigid couplings?

Black oxide finish on our steel couplings is formulated as part of the total performance of the coupling. The black oxide affects the anti-stick-slip characteristics and helps keep the torque rating of the screw within its design parameters. The black oxide has corrosion resistant properties for indoor environmental applications. However, black oxide (more…)

Why is a cross-cut on a coupling important?

A cross-cut is a lateral cut made halfway through the coupling. It is added to our one-piece and two-piece clamping couplings only. Similar to a relief cut, the cross-cut allows more tolerance for different size shafts. The cross-cut will help the rigid coupling clamp more securely and transmit power more efficiently even with these slight variations.

What is a shaft tolerance?

Shaft tolerance is the amount of allowable difference between the size of collar or coupling and the size of the shaft that will still allow the component to function. Ideally, a ¾” collar will be used on a ¾” inch nominal shaft. The closer to nominal the better – if the difference is too great, the collar may not even clamp. A difference of even ½ millimeter is quite high. Climax bore tolerances can be found in our catalog and online.

What is torque capacity?

This is a very commonly asked question, and it depends on each individual application. For a collar, the key figure is the axial load of the collar, and for a coupling it is how much torque it can transmit. Consult our technical data sheet for typical maximum values for axial load and torque data. Please note the data presented are based on limited test results and are not a guarantee of minimum or maximum values under all conditions. These values are only a guide, and must be evaluated by customers based on individual application.

What is a Climax Keyless Locking Device?

Keyless Locking Devices (KLDs) are mechanical bushings used to connect power transmission components onto rotating shafts. Without the use of keyways, KLDs eliminate the problems associated with backlash including fretting, corroding, and wallowing. KLDs work with straight bores and generous tolerances, reducing component machining and complexity costs. In addition, KLDs are installed and removed using simple hand tools; no heat or high forces are required.

Climax Keyless Locking Devices include, keyless locking assemblies, keyless rigid couplings, shrink discs, and single nut locking assemblies.

What materials are used to manufacture Keyless Locking Devices?

Climax Keyless Locking Devices are manufactured from high carbon and alloy steel and stainless steel.

What is the required surface finish & lubricity for Keyless Locking Devices?

Climax Keyless Locking Devices carry rated capacities that rely upon both lubricity and surface finish. Components to be mounted should be machined to achieve a surface finish of between 63 and 125 µIN RMS. A surface finish outside this range could result in a reduction of the load carrying capacity of the connection. Lubricity is likewise critically important to the successful application of our products, as it directly affects the Coefficient of Friction (COF) between mated components. Our internal locking assemblies are supplied and installed with ordinary machine oil on all locking screws and mated surfaces to achieve a COF equal to .12. Our external shrink discs and keyless rigid couplings require a solvent cleaned and dry shaft interface to achieve a COF equal to .15.

What is the safe operating temperature of a Keyless Locking Device?

Climax Keyless Locking Devices are designed to operate through a temperature range of 0º to 400º F. Note that mated components of dissimilar materials may react to temperature increases at different rates. Please consult with a KLD Product Specialist regarding such applications.
