Extensive knowledge, extensive ability, extensive products. Customer needs are the centre of our business.
At jbj Techniques, we pride ourselves on rising to a challenge, especially when it supports the transition to clean energy. A recent project involved the development of a bespoke solution for a customer replacing a diesel engine with a 250 kW, D355 frame electric motor on heavy equipment. Critical to this retrofit was the ability to interface the new motor with the existing SAE 1/SAE 14 over-centre clutch, preserving the option to revert to diesel if required.
Working in close collaboration, our design engineers and skilled machinists created a special 800 mm diameter cast iron bellhousing to connect the motor flange to the clutch housing. We also produced a custom coupling to convert the motor shaft to an SAE 14 flange, enabling full mechanical compatibility with the clutch rotating group.
Our recently installed Puma V8300M CNC machining centre, with a 24" chuck and 800 mm component capacity, proved invaluable for this large-format work. Aligning design with manufacturing capabilities from the outset ensured precision, efficiency, and a successful result.
The raw casting, weighing 230 kg, was poured at a trusted local UK foundry using patterns we own. jbj Techniques also designed and built all necessary tooling and handling equipment in-house.
Coupling components were machined from locally sourced steel.
In-process inspection was streamlined using our new Keyence XM-5000 handheld CMM system, allowing us to bring the metrology tools directly to the component, saving time without compromising accuracy.
Our machine shop combines over 200 years of collective hands-on experience with a full suite of modern and traditional equipment, from state-of-the-art CNCs to manual lathes and even an anvil. This blend allows us to support both bespoke, one-off jobs and large-scale production runs with short lead times.
This successful project has expanded our capabilities and product range. We can now offer fully UK-manufactured, low-carbon-footprint, cast iron bellhousings for D355 frame motors (800mm flange), available in standard lengths of 355 mm, 380 mm, and 400 mm. Custom sizes also available on request.
