SWR SPA1707 Ummantelte Keilriemen

The SWR SPA1707 is a wrapped V-belt in section SPA (AV13) to DIN 7753-1 / ISO 4184, transmitting power by friction through its wedge flanks in the pulley groove. All three length datums at a glance: inside length Li 1,662 mm, datum length Ld 1,707 mm, outside length La 1,725 mm. When cross-referencing other brands, always compare the same length datum.

The cross-section measures 12.7 × 10 mm at a 40° wedge angle. Any V-belt of section SPA (AV13) with datum length 1,707 mm is a drop-in replacement, regardless of brand. Key design data: minimum recommended pulley datum diameter 90 mm; weight 0.123 kg per metre. The fabric wrap protects the tension cord against abrasion, oil and ozone — the robust standard for industrial drives (belt speeds up to about 30 m/s). Permissible ambient temperature range: -40 to 100 °C.
