Cross Shaft Clamping Elements, by means of frictional forces, provide connection of all types of transmission equipment to their respective shafts, enabling transmission of both torque and axial thrust loads. Precision tapered thrust cones within the clamping elements create high pressure between shaft and hub to securely fasten pulleys, sprockets, gears etc. Stresses in both hub and shaft are similar to heavy press fits, however, the actual stresses are easy to calculate; and the hub can always be easily dismantled without damage to it or the shaft; only a torque wrench being required for both assembly and disassembly.
Precision transmission of torque with no backlash is obtained with shaft clamping elements, without the need of tight manufacturing tolerances of mating components. Simplified designs can enable manufacturing cost reductions, coupled with easy assembly and disassembly.
Cross Shaft Clamping Elements provide an alternative method of connecting hubs to shafts to:-
Tapered Bushes, Hydraulic Clamping Systems, Fine-bored Hubs, with Precision keyways & Locking Setscrews ,Heavy Press Fits & Welded Components.
The following types are available:-
RCK 15 - RCK 13 - RCK 16 - RCK 70 - RCK 71 - RCK 80 - ACE 81 - RCK 61 -

Rigid Couplings
Various Ruland Rigid Couplings
Ruland rigid couplings are available in one and two-piece designs, with and without keyways, in aluminum, carbon steel, and stainless steel. A large number of standard sizes are available in straight and step bore combinations to fit shafts ranging from 1/8" to 2" in the inch series and from 3mm to 50mm in the . Inch to metric conversion couplings are also available by special order. Shaft couplings are stamped with the Ruland name and the bore sizes for easy identification.
The one-piece rigid coupling wraps around the shaft, providing high torsional holding power without the shaft damage and fretting inherent when a set screw style coupling is used. The two-piece rigid coupling has the additional benefits of allowing for disassembly and maintenance without removal of other components. Two-piece couplings also feature opposing hardware for dynamic balancing.
Extra steps are taken in the manufacturing of rigid couplings to provide important performance benefits. As one of these steps, the bores of Ruland straight bore couplings are precision honed. Honing of the bores provides several benefits that enhance the overall performance of the coupling. Applications that require strict control of shaft alignment benefit greatly from honing, which assures both bores are collinear. Honing also corrects any residual distortions caused by stresses introduced during the manufacturing process, resulting in a round, precisely sized bore. Proper sizing and geometry assures a large percentage of shaft contact and greater torque transmission ability.

General Fabreeka® bushing information:
- Minimum wall thickness of 3/32" is recommended
- Fabreeka® bushing ID is the same as the bolt OD, and the bushing OD is the same as the hole it will fit into.
- To facilitate inserting Fabreeka® bushings, they can be lubricated with a soap solution.
- In general, tolerances on rubber impregnated bushings need not be controlled to the same closeness as required for metal fits, since Fabreeka® is a compressible/flexible material.
- In general production, the tolerance on bushing dimensions is ±1/32". If closer tolerance is required, please contact Fabreeka's® Engineering Department.
Fabreeka® washers are used under the steel washers of the hold-down bolts of Fabreeka® mountings to absorb the rebound shocks and afford complete isolation by eliminating the transmission of vibration through the bolts and steel washers. It also aids in preventing the bolts from becoming loose.

With the full faced flanges out of PE 100, AGRU offers a perfect joining possibility to other materials.
Since a lot of fitting-accessories (slide valves, flaps or subterranean hydrants) are manufactured out of gray cast iron with spheroidal graphite, these full faced flanges were developed. By using them an unproblematic integration of other materials into a piping system out of polyethylene is possible. The full faced flanges are available in the dimensions 90, 110, 125, 160 as well as 180 and in the dimensioning SDR 11.
The constructive design of the full faced flange allows a permanent leak-proof connection. The hole pattern is in accordance with DIN 2501,
sheet 1. The long welding ends allow butt welding as well as electro-fusion.
A permanent stability as regards form and pressure is ensured by the use of PE 100 material and the integrated steel core.

CHARACTERISTICS
1. SIMPLE MANUFACTURE
Large possible tolerances and simple turning treatment guarantee
cost-efficient production.
2. EASY MOUNTING
Only a few screws must be tightened, angle-exact alignment between
hub and shaft is possible in every position, fitting work is not required.
3. EASY REMOVAL
RINGFEDER® Locking Assemblies have releasing threads, thus no
additional auxiliary devices are required. Series 7012 is even self-
releasing (no releasing threads).
4. HIGH FATIGUE STRENGTH UNDER ALTERNATING TORSIONAL STRESSES
Neither shaft nor hub feature grooves, thus no attenuation of the
components. Shaft and hub can be designed definitely smaller (light,
cost- and space-saving construction is possible).
5. NO DANGER OF DEFLECTION
Locking Assemblies RINGFEDER® are absolutely free from backlash.
6. OVERLOAD PROTECTION EFFECT
In case the admissible load is exceeded, the Locking Assemblies will
slip. That way, valuable machine components are safeguarded against
damage. However, the Locking Assemblies are subject to the same
laws as all other frictional locking connections and are not suitable for
use as friction clutch.

Clamping sets constitute a particularly elegant way of a shaft/hub connection. They combine the advantages of a no-play clamped connection that is detachable, a high capacity for torque transmission and minimum structural and manufacturing requirements of the system to be clamped.
Ideal applications for instance arise in the assembly of:
• gears
• V-belt pulleys
• sprockets
• belt pulleys
• couplings or
• levers

Shaft Collars
Ruland shaft collars are offered in multiple styles to fit shafts ranging from 1/8" to 6" in the inch series and 3mm to 80mm in the metric series, in a variety of materials and finishes. Collars are stamped with the Ruland name and the bore size for easy identification.
Extra steps are taken in the manufacturing of a Ruland shaft collar to provide important performance benefits. For example, Ruland collars are single point faced (indicated by the circular groove on the face) during the boring operation to insure perpendicularity of the face to the bore. Perpendicularity is important for alignment when collars are used as a bearing face, a mechanical stop, or for mounting other components.
One-piece clamp style shaft collars wrap around the shaft for even distribution of clamping forces. This results in a tight fit and greater holding power, without the shaft damage caused by set screws. Ruland uses carefully selected materials and proprietary processes to ensure that the clamping gap remains open for simpler and more precise adjustment, installation and fit.
Two-piece clamp style shaft collars offer the same benefits of the one-piece clamp collars with additional versatility and convenience. They are easily disassembled, reducing labor and downtime when adjustment, removal, or replacement is necessary. Ruland keeps both halves of its two-piece collars together throughout the manufacturing process to assure a perfect match for proper fit, holding power and alignment.

For use on standard round shafts, these shaft collars are sized .001” to .002” over nominal to allow a smooth slip fit to the intended location. Offered in set screw style, one-and two-piece clamp-type, as well as Stafford’s own Hinge Collar. Plus a broad assortment of problem solving collars from our Solution Series of Special Purpose Mechanical Components.

Powerful and compact
Torque transmission is possible by means of PETER shrink-on disks.
The principle is thoroughly convincing especially in input and output connections by means of hollow shafts. Contrary to keyed connections, the non-positive connection by means of shrink-on disks permits considerably thinner wall thicknesses for the hollow shafts since the greatest part of the torque transfer is absorbed by the shrink-on disk and the shaft is not weakened by additional slots.
This results in lower shaft diameters and consequently volumetric savings in the remaining system. Weight, moments of inertia and space can be elegantly saved in this manner.
Other factors in favour of shrink-on disks are
• high performance density
• detachable connection
• rapid and simple assembly
• economic use
