Rigid couplings serve as compact, economical components for the timing, joining or aligning of shafts at lower speeds and torque, particularly where zero backlash is desired. They are not intended for use as a critical part of a drive line or as a substitute for flexible or universal joints or other power transmission devices. As they are applicable for aligned shafts only, they are the most basic but often most cost-effective coupling option.

There are two basic styles of rigid couplings: the set screw type and the clamping type, which comes in both one-piece and two-piece styles. Most couplings are available in steel, stainless steel and some smaller sizes in aluminum. Almost all couplings (except smaller bores) are available with a keyway for increased ability to transfer torque. The rigid set-screw coupling (Climax premium "RC"-Series) like the set-screw collar is secured to the shaft by a set-screw that impinges upon the shaft.

The clamping screws are arranged in pairs. Climax recommends that Climax Premium Clamping Couplings be installed by tightening the paired screws alternately, in several steps so that the tension is distributed evenly. As each screw is tensioned, it tends to relax any tension developed by its companion screw. Hence, tightening one screw completely before tightening the other could lead to an unequal distribution of tension. When disassembly tension should be relieved in a similar manner.

Rigid couplings should not be used on misaligned shafts. Misalignment could generate lateral forces which could lead to premature failure of the shaft, bearings or couplings from wear and metal fatigue.

Rigid sigmoidoscopy has no longer the value it had in the past, before the advent of videocolonoscopy (flexible sigmoidoscopy). However, it may be still useful in ano-rectal diseases such as bleeding per rectum or inflammatory rectal disease, particularly in the general practice and pediatrics.

There is an accurate chart describing the measurements of the end covers in our Tech Info section. Click here to go there.

Dry Link "keyed" couplings are used in batch process plants and manifolds for preventing accidental cross-contamination of chemicals. Please see details under "Specialty Products" on our website. Absolutely. Typically, these sanitary couplings have Triclover end connections and are hand polished with an internal 25 RA surface finish. We can even supply FDA or USP approved seals. Please see details under "Specialty Products" on our website.

A range of reusable couplings is available specifically designed for on-site attachment. The stainless steel or aluminium bronze couplings (& High Tensile Polymer in 1", 1?" & 2" sizes) complement the riser, having a good resistance to aggressive water and the benefits of long life with low maintenance.

We are often asked by those who first hear about us "Why is Rigid Design Solutions different? Why should I choose Rigid over somebody else?" We think that not only is this a fair question, it is an important one. There are thousands of web design companies on the Internet, many of them offering seemingly inseparable services.

Couplings require little, if any maintenance. Sand, mud and ash should be rinsed or brushed off after each use. All gasket faces should be kept free of sand, grit etc. and lubricated with silicone or a light film of petroleum jelly.

Provided the manufacturer's instructions are followed, the couplings are stronger than the riser. The riser will tear or burst before the couplings lose their grip.

Cam and groove couplings have traditionally been manufactured to the US Military specification MIL-C-27487. This specification covered the dimensions and machining tolerances, the materials, the closing torque, part numbers, pressure ratings, finish, inspection procedures and packing requirements of the product. Compliance to this specification ensured inter-changeability of parts from different manufacturers.

It is very important that you specify the correct coupling for your application. Please select the desired coupling features by clicking here.

Yes the standoffs may be easily cut to custom lengths. The standard sizes range from 3“ to 5 3⁄4” and additional rods are available to 48”.

Some persons develop Huntington disease as adults, but without the chorea. They may appear rigid and move very little, or not at all, a condition called "akinesia." These individuals are said to have akinetic-rigid HD or the Westphal variant of HD.

Yes. Though not as common, several grades of DYMAX products are hard and rigid with a shore hardness of D80 or higher.

All airships use an envelope (balloon-like bag of gas) to lift the airship. Some used a metal "skeleton" or frame inside the envelope to give shape to the ship; these were called rigid airships, and examples included the R100 and R101 in England, the Graf Zeppelin and Hindenburg in Germany and the Akron, Macon and Los Angeles in the USA.

This type of connection is typically used for joining unlike pipes, such as iron pipe to plastic pipe.

Yes. Select the right nozzle to suit the coupling then select the correct Ultra Clean projectile and fire through the line.

Most of the major brands are using #8-32 threads for rifle/handgun accessories and #5/16" - 27 thread for shotgun accessories. If you plan to cross match another brand cleaning tool with Kleen-Bore, please refer to the chart below.

Click Why Choose Superior Radiant to get our take on why we feel Superior Radiant tube heaters are bar none the best in the industry. A bit of advice is in order. Never let an infra-red salesman representing any particular manufacturer persuade you that their tube heating system, is 80%, 88% or 95% efficient. There are no published CSA standards used by any of the infra-red tube heater manufacturers for determining the efficiency of an infra-red tube heating system.

Tubing becomes hard when exposed for long periods to the lipids found in human skin. Treat the tubing with a vinyl protector once a month to help slow down the process.

Strength & Durability. All Eskimo Take-A-Part kayaks are built in expedition-grade Kevlar/Graphite construction. They are able to withstand blows which would destroy the frames of folding kayaks. The tough hardshell surface can take the wear and tear of razor-sharp corals, oyster shells, or barnacles, which would cut and tear the skin of a folding kayak. All materials used in these boats are corrosion-resistant and unaffected by ultraviolet rays and humidity.

The rigid mat is double the thickness and has handles. You use the rigid mat to imprint the majority of the stamping job. The floppy has no handles and is about half the thickness of a rigid which allows you to bend the mat at a 90 degree angle. The floppy mat can be used to stamp around the edges of the stamping area, walls, stairs and hard to get at areas.

Rigid arrays are often necessary when the rig needs to be flown high and out of the way of television cameras (ala Academy Awards) or for other specialized situations. The M.LINE’s Integrated Rigging System is unique in that it is instantly convertible between a fully collapsible operating mode, which is of most useful for general flying, and a completely rigid, inflexible curvature, which is most useful for groudstacking, flown installations, or these unique coverage needs.

We get this question all the time. As these panels span a large open area (your truck bed), we made the cover as strong and as rigid as possible, but also as light as possible. To make it strong enough to stand on, we would have had to make it much heavier, which would defeats the purpose of having an easy-to-remove cover. Also, as the finish on the broad surface of the panels is an automotive finish, you should treat that finish just as you would any other painted surface of your truck.

No. the concept of "territory" is not rigid to any geographical location, rather it can be used for geographical location also i.e we can consider "territory" as geographical location as well to assign customers from a particular location. According to CRM experts, "territory" is a means to identify and place a set of customers under a particular category. It helps for the further process of customer issues.

A rigid borescope uses a series of individual lenses or a long gradient index relay lens to relay the image of the objective lens to an image plane where the eye lens can magnify it and present it to the eye for viewing. A flexible borescope uses a coherent fiber bundle with thousands of individual fibers to relay the image from the objective to the eyepiece.

The magnification depends on two factors - The field of view and the distance between the Borescope tip and the object being viewed. if you need high magnification view then choose an instrument with a narrow field of view and get as close to the object as possible.
