jbj Techniques Limited have been experts in power transmission components including couplings since 1974. This organisation provides probably the widest range of power transmission couplings available within the UK. Their range includes miniature couplings, all steel gear couplings, flexible spider couplings, shaft couplings, torque limiting couplings, disc and grid type couplings, ATEX compliant, and shaft locking devices.
ATEX compliant 'JXL' torsionally resilient, anti-static couplings, of pin and bush design, comprise of two fully machined steel flanges coupled via a series of drive pins and hytrel flexible elements. The elements have the ability to absorb shock loads and dampen vibration.
This particular design of coupling does not produce static and does not sustain burning. Maximum shaft diameters up to 400mm with torques of 300,000Nm and speeds up to 11,000rpm can be accommodated.
These couplings are ATEX certificated to directive 94/9/EC II2GD-IM2-T6 requirements, harmonised standards EN13463-4, EN13463-5, EN50303, and EN13463-1.
Other ATEX certificated couplings from this organisation include tyre couplings produced in accordance with the requirements of regulation 94/9/CE (TEX95) of a group ll device, category 2G or 2D (zone 1) and temperature class T4.
There are various criteria in specifying the most suitable coupling for your application but jbj Techniques Limited will guide you all the way to obtain the right power transmission couplings.
The complimentary coupling element size selection chart available from jbj Techniques is ideal for selecting spider and gear coupling elements especially wen you are unsure of specific size, or if original element is beyond recognition after hard service life, this useful chart will assist in specifying the correct sized element. Customers have even successfully sized coupling elements from just a quarter piece left from their original coupling.

DC power units and mini power packs are designed to achieve optimum electro-mechanical and hydraulic performance for an extensive range of mobile and static applications. DC motor and multiple pump applications are a focused area of our expertise.
DC power systems are self contained modular power pack systems with a wide range of standard pumps, motors, switches, mountings, valves, and reservoirs plus custom options. Short series of custom power packs, available fully assembled or in kit form, are easily built and cost effective.
The HE power pack is based on a versatile platform allowing you to combine 80 - 134 mm motors (0.3 - 4.5 kW) with a variety of pumps (0.24 - 5.7 cc/rev). A unit can individually control up to four hydraulic cylinders and the core of the system consists of two different adaptors with alternative shapes and variable assembly direction. jbj Techniques Limited are also the UK's distributors of Haldex / Concentric hydraulic components.
Versatility, power, compactness and low running costs are the main characteristics of hydraulic vane pumps available from jbj Techniques Limited. All the components subject to wear are contained in a cartridge unit easily removed for inspection and replacement without disconnecting the pump from the circuit. This drastically reduces expensive machine down time.
The cartridge contains a rotor, vanes and inserts, a cam ring, and two covers. During operation the rotor is driven by a splined shaft coupled to the drive unit. As the rotation speed increases, centrifugal forces, in combination with the pressure generated behind the vanes, push the vanes outwards, where they follow the profile of the cam of the ring with a sufficient contact pressure to ensure adequate hydraulic sealing.
The two opposed pumping chambers formed by the elliptical profile of the cam cancel out radial loads on the shaft bearings, thereby giving them extremely long lifetimes.
The versatility of these hydraulic vane pumps enables them to meet the requirements of the most varied industrial
applications. As well as their proven high reliability and excellent volumetric efficiency in all working conditions they operate with particularly low noise levels. This is made possible by the special profile of the cam ring and the use of a 12 vane rotor to reduce the amplitude of the supply pressure pulses, thereby reducing induced vibrations.
The range of ATEX certificated to directive 94/9/EC requirements products available from jbj Techniques is constantly growing. The organisation have been manufacturing the range of JXL anti-static couplings and cast iron bellhousings in the UK since 1984, specifically for use in hazardous areas.
Equipment for hazardous areas such as flywheel couplings, are manufactured to directive 94/9/EC II2GD-IM2-T6 and harmonised standards EN13463-4, EN13463-5, EN50303, and EN13463-1. Products such as screw pumps are ATEX approved for use in explosive atmospheres Zones 0 & 1 and API 676 compliant. Terminal boxes used on the JBJ range of hazardous area float switches and thermostat TRI types have also been ATEX certificated at source by the manufacturer in accordance with the requirements specified within directive 94/9/EC.
ATEX directive is in accordance with the following types of protection and ambient temperature standards:

Gear-couplings are the foremost coupling type. They can do things that many other coupling types are unable to perform, or that need expensive modifications and de-rating to function. Gear couplings have the highest power density, offer more variations, a wider size, torque, and bore capacity than any other coupling type. They are easily modified for shear pin service, floating shaft type, vertical applications, electrical isolation, limited end float, and can have a brake drum or disc added. While some features may be available on other couplings, it is typically easier and cost effective to modify a gear coupling. With all these advantages, the gear coupling is used on more applications versus the nearest competing coupling type.
