d: Preferred coil wire diameter: 1,2  –  1,4 – 1,5   or 1,6mm

English name: 18 – 17 – or 16 Gauge.

s: Any pitch size  between 3.2 and 12.7mm is  selectable by default.

Preferred spiral wire pitch: 3.2 – 4.2 – 5 – 6 – 6.35 – 7.2 – 8.4 or  12.7mm

English name: 96 – 72 – 60 – 50 – 48 – 42 – 36 or 24 spiral turns/foot.

BW: Bandwidth (maximum band width)

Any width (metric or inch) between 300 and 1500 mm can be selected as standard.

Wider or narrower tires on request.

R: R = qx BW  (Nominal radius around which the belt can be guided)

type designation: Band – Bracket – Pitch – Pitch / Diam. – Diameter.

d: Preferred spiral wire diameter: 1.2 – 1.4 – 1.5 or 1.6mm

English name: 18 – 17 – or 16 Gauge.

s: Any pitch size between 3.2  and 12.7mm is   selectable by default.

Preferred spiral wire pitch : 3.2 – 4.2 – 5 – 6 – 6.35 – 7.2 – 8.4 or 12.7mm

English name: 96 – 72 – 60 – 50 – 48 – 42 – 36 or 24 spiral turns/foot.

BW: Bandwidth (maximum band width)

R: R = qx BW R = Nominal radius around which the belt can be guided.

The middle bracket is attached exactly in the middle in the tire. SPECIAL: By mounting the bracket off-center in the tire, the deflection radius R can be adapted to specific requirements within certain limits.

Due to the many meters of belt, the varying product load and temperature variation, every spiral tower is equipped with a facility to compensate for belt length differences. This is often done by means of one or more "tension loops" where the belt can lengthen and shorten.
