Product overview
Spoke load-cell body
A raised central threaded opening sits inside the circular metal body. Mounting openings surround the center, with a short cable exit at the side.
The low-profile spoke structure uses the shear-stress principle for tension, compression and weighing.
Central thread and capacity-dependent dimensions
The top drawing shows the eight-hole construction. The 100–300 t rows specify sixteen mounting positions. ØD is the smaller hole diameter; ØD1 is the counterbore diameter. Dimensional units require confirmation. Confirm the hole count, thread and mounting dimensions for your selected capacity before machining the fixture.
