JXL-couplings
JBJ Techniques offers ATEX-compliant JXL torsionally resilient couplings, of pin and bush design.
They comprise 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. The couplings do not produce static and do not sustain burning. Maximum shaft diameters up to 400mm with torques of 300,000Nm and speeds up to 11,000rpm can be accommodated.
The JXL range of resilient couplings can cope with angular, radial and axial misalignment.
Furthermore, they are torsionally resilient, non-lubricating and capable of operating between temperatures of –50°C and +105°C.
The elements are flame resistant, anti-static and have NCB acceptance for use underground in coal mines (number A2032).
The couplings are ATEX certificated to Directive: 94/9/EC II2GD-IM2-T6. Harmonised standards are EN13463-4, EN13463-5, EN50303 and EN13463-1.

JBJ Techniques is a specialist supplier of high-quality products for the mechanical power transmission and fluid power sectors. The company offers a high level of in-house expertise plus a huge selection of products to meet a very broad range of customer applications.

From specification, through technical advice and manufacture to after-sales support, JBJ Techniques provides a comprehensive and valued service to the power transmission and hydraulics industries. The company fields a UK-wide team of technical sales engineers to ensure that the business is close to its customers, and it enjoys excellent associations with European manufacturers, acting as sole UK distributor in many case.

JBJ’s team is recognised for its expertise in the selection and configuration of hydraulic and mechanical transmission systems. Able to draw on an extensive product range that provides the building blocks for bespoke systems both large and small, the in-house design team offers a complete service, ranging from an assessment of customer requirements to full technical backup, including engineering calculations, CAD-based system design, system build and certification. Moreover, customers can take advantage of JBJ’s own machine-shop facilities and skilled craftsmen to guarantee quality and control cost.

JBJ Techniques provides probably the widest range of couplings available within the UK with 14 different designs and 22 different styles of gear couplings alone. The product portfolio 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.

However, as extensive as the selection is, couplings make up a fraction of JBJ’s portfolio. In addition, the company can provide gearboxes, clutches, pumps, hydraulic motors, flow meters, fluid power accessories — including cooling systems, reservoirs, seals and indicators — as well as a variety of bellhousings and flanges, to name just a few of the product categories.
