The VULKAN Integrated Shaft Coupling (ISC) combines in a unique way the well proven RATO DS torsional rubber coupling with a double cardanic floating shaft.
The working principle of the ISC is based on the fact that the flexible rubber element of the RATO DS coupling transmits the torque primarily by shear stresses which have a pre-dominant radial/circumferential component.
Chain couplings are able to transmit higher torque than their shafts, making them ideal for high torque applications. Available with a pilot bore, finished bore or taper bushing (face or hub), flanges are linked together
with duplex roller chains enabling them to accommodate up to 2° of misalignment.
To help provide maximum service life and reliability, particularly for high speed applications, SKF recommends fitting all chain couplings with a cover and lubricating them properly. If a chain coupling is to be subjected
to reversing operations, shock or pulsating loads, or other severe operating conditions, select a coupling one size larger than normal.
The T Series is intended for such applications where telescoping function is required in a small space.
Because one of the cross bearings needs to be hollow to enable the required stroke, this series is applicable in such cases where the swing diameter has a given allowance on either the driving side or driven side
Very high-torque ratings, along with unparalleled bore capacities, give this coupling a great advantage over other types of couplings. SKF Gear Couplings are rated up to 1 310 kNm with a maximum bore of 525 mm. This is a heavy duty coupling with incredible design flexibility, making it an economical choice for many applications.
The unique design of the gear couplings tooth crowning dramatically reduces backlash and radial clearance. The hub bore capacities are the largest in the industry, allowing for low cost and long service life. In some applications it is not possible to go up in coupling size to accommodate a Floating and vertical shaft single engagement † pages 43 and 44 Double engagement † page 32 Double engagement spacer † page 35 Double engagement † page 32 Single engagement † page 33 Slide single and double engagement † pages 37 and 38

dimensional restraints or operating speeds. For coupling sizes over size 80GC, there are two options for increasing the torque capacity of the SKF Gear Coupling.
In high output (kW) and high torque applications where vibration, shock loads and misalignment occur, SKF Grid Couplings are an excellent choice. The unique design of the grid and hub teeth enable these couplings to accommodate movement and stresses from all three planes, which can reduce vibration levels by as much as 30%. The tapered grid element is manufactured from a high strength alloy steel. The grid, which, is the primary wear component of the coupling is designed for quick and easy replacement. Unlike other couplings, the hubs and other components are not disturbed. This makes realignment virtually unnecessary and further reduces downtime and maintenance costs.
Lenntech can provide all types Victaulic couplings. Designed to make installation and connecting your Reverse Osmosis and Ultra Filtration systems fast and easy. Reducing field man-hours to a minimum. Victaulic couplings come in a variety of styles and with any type of gasket to suit your needs. Style 75 is a flexible coupling designed for moderate pressures up to 34.5 bars. Style 77 is recommend in system with working pressures up to 69 bars while still allowing flexibility to absorb movements in the system. From brackish or seawater intake to membrane assembly and water distribution.
Jaw couplings provide a cost-effective solution for standard power applications, cushioning moderate shock loads and dampening low vibration levels. Maintenance-free and easy to install, jaw couplings are available with a “snap wrap” element allowing element replacement in situ. Urethane and hytrel elements have a greater power rating than nitrile elements and are recommended for applications where a compact, high torque solution
