| For the correct selection of high-speed, dynamic or reversing precision drives and shaft couplings. Only backlash-free couplings are able to fulfil these requirements. The wide selection of backlash-free and price competitive coupling variations underline our market leadership. We have a backlash-free coupling for every application which optimally harmonises with your drive system. |

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 -
ACE 54 - CCE 55 - RCK 40 - RCK 45 - RCK 11 - RCK 50 - RCK 19 - RCK 95

| Rotation is transmitted through a central disc that slides over the tenons on the hubs under controlled preload conditions to eliminate backlash. Discs and hubs are available in different materials and configurations to suit different applications. These couplings provide generous radial compensation and easy maintenance. |

For more than 25 years we have successfully been supplying shaft couplings for ships and other non-positive shaft couplings in various designs for the construction of motors and gearboxes and plant engineering. Our range includes designs with shaft diameters of up to 250 mm. Our customers benefit from the many years of experience in this field.
Rigid couplings from WEISS are available as sleeve couplings and flange couplings, both in a steel or saltwater- proof design. In addition, we also offer flywheel flanges as joining elements for diesel engines. |

Shaft guidance systems or ball-based or plain linear guidance systems for various areas of use and applications. Linear ball bearings are available as a light range, compact range and heavy range. Mating tracks can be solid shafts, hollow shafts or supported shaft and rail units.
The range is rounded off by a large selection of linear ball bearing and housing units and linear plain bearing and housing units. In this case, the linear ball bearings or linear plain bearings are supplied already mounted in ready-to-fit housings.
A large number of shafts (with or without machined features), shaft and support rail units and comprehensive accessories allow a broad spectrum of applications.

* single Shaft Assemblies (SA series) are a complete pre-engineered assembly which simplifies the use of a linear bearing system in a mechanical positioning application. Each assembly has a steel shaft pre- mounted to a black anodized precision machined aluminum support. The pre- drilled base mounting holes in the 6, 12, 18, and 24 inch aluminum supports allow for easy customer mounting. The SA assemblies come in standard lengths from 6 to 192 inches and with shaft diameters from 1/2 to 2 inches.
* Twin Rail shaft assemblies are a complete pre-engineered assembly which simplifies the use of a linear bearing system in a mechanical positioning application. The two steel shafts are mounted and pre-aligned on the common base, therefore eliminating the time consuming alignment process normally required for two seperate shafts. The pre-drilled base mounting holes in the aluminum support allow for easy customer mounting. Each 6, 12, 18, & 24 inch aluminum support has two threaded holes at one end, to assist in leveling the assembly in the final mechanical structure. The TRSA assemblies come in standard lengths from 6 to 192 inches, and with shaft diameters from 1/2 to 2 inches. |

The shafts support rails provide a support to the shaft and are used in combination with the housing and bearing units of open design.
All of the shaft support rails are made in aluminum alloy.
They are available in multiple versions :
- FTSN, FTSW and FTSWA for mounting from the top
- FTSU for mounting from the bottom
- FTSS and FTSC for lateral mounting |
