ATEX rated couplings & bellhousings

jbj Techniques Limited has long been established as a quality supplier of bellhousings and shaft couplings for hydaulic pump drives, manufacturing the range of JXL anti-static couplings and cast iron bellhousings in the UK since 1984, specifically for use in hazardous areas. The cast iron range of bellhousings, prefix GG is also available in high strength (SG) iron, prefix GGG, in addition we produce this range to suit NEMA motor flange dimensions without the use of adaptor plates. These bellhousings are a one-piece component founded in the UK with minimal (trace) aluminium, magnesium, titanium and zirconium content. Final machining is effected at jbj premises. In some instances a steel flange may be bolted to the pump mounting face to facilitate the fitment of larger pumps. The bellhousings have been subject to a 20 Joule impact test with no damage noted. If required the housings can be supplied with full chemical analysis and test bars. This must be requested at the time of ordering. ATEX compliant 'JXL' torsionally resilient couplings, of pin and bush design, comprise two fully machined steel flanges which are 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 is able to accept angular, radial and axial misalignment, 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. All JXL couplings are capable of accepting a momentary overload of twice nominal torque. for much more information!
