Lovejoy's S-Flex coupling design is simple, ensuring ease of assembly and reliable performance. No special tools are needed for installation or removal. S–Flex couplings can be used in a wide variety of applications.
Its design is comprised of three parts. Two flanges with internal teeth engage an elastomeric flexible sleeve with external teeth. Each flange is attached to the respective shaft of the driver and driven and torque is transmitted across the flanges through the sleeve. Misalignment and torsional shock loads are absorbed by shear deflection in the sleeve.
In all designs, pre-molded teeth along the diameter of the sleeve engage with teeth of the joint flanges. No clamps manufacturers or screws are needed to connect the flanges with the flexible sleeve which securely lock together under torque for smooth transmission of power. All three sleeve materials are highly elastic which permits the S–Flex coupling to protect connected equipment from harmful shock loading, vibration, and shaft misalignment.
The S–Flex coupling from Lovejoy offers combinations of flanges and
sleeves which can be assembled to suit your specific application. Thirteen
sizes are available with torque capabilities that range from 60 in-lb to
72,480 in-lb.

Precision motion control applications require mechanically tight systems, especially between motors, driven loads, and feedback devices, to ensure accurate positioning. Such systems often require shaft joints that are both torsionally rigid, to accurately transmit rotational position and laterally flexible to accommodate shaft misalignment.
Servometer couplings exhibit both low windup due to the bellows' radial rigidity, and low side thrust due to the bellows' lateral flexibility. Other coupling types have either low windup or low side thrust, but not both.
Since the flexible element is a bellows, the coupling can absorb parallel shaft misalignments of 0.068 in., angular misalignments as large as 31°, or axial movements of 0.230 in. while transmitting torque. Servometer's stock lines of flexible shaft couplings are available with stainless steel hub bore diameters ranging from .079 in. (2 mm) to 1.0 in. (25.4 mm), and with torque capabilities ranging from 2.0 in-oz (1.4 N-cm) to 4000 in-oz (2825 N-cm). Outside diameters range from 0.250 in. (6.35 mm) to 2.40 in. (61 mm) and overall lengths from 0.480 in. (12.19 mm) to 2.16 in. (54.9 mm). Specialized dynamic requirements can be custom designed to fit customer specifications.
Some unique characteristics of Servometer bellows-type flexible shaft couplings are:
- Extremely low elastic windup
- Zero backlash
- Zero cyclic speed variation during 360° rotation
- Minimal side loading
Typical applications include:
- Professional encoders
- Resolvers
- Servos
- Motion control instrumentation
- Robotics
- CNC machine tools
- Precision positioning |

The original Continuous Sleeve, or “C” coupling, offers a lightweight, compact, and simple design without compromising torque carrying capacity. The Flanged Sleeve, or “F” coupling, is available in exposed or shrouded bolt styles in which the number of supplier of bolts, size of bolts, and bolt circle are identical with industry standards. The nylon sleeve gear joints, Nyflex and Mite, are compact, lightweight couplings that use a nylon sleeve and two sintered iron hubs. Lubrication is not required with the nylon sleeve. Lovejoy also has an All Metal Labyrinth sealing coupling and an Alloy Steel coupling. The All Metal Labyrinth Seal coupling is a flanged sleeve style, but uses no elastomeric professional seals. The Alloy Steel coupling is made from AISI 4140 steel. |

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 professional 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 manufacturers 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 Clamp 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
