SWR A43.5 Ummantelte Keilriemen

SWR A43.5 — a wrapped V-belt, section 13 (A) to DIN 2215 / ISO 4184, for friction power transmission between two pulleys. All three length datums at a glance: inside length Li 1,105 mm, datum length Ld 1,135 mm, outside length La 1,155 mm. When cross-referencing other brands, always compare the same length datum. The cross-section measures 13 × 8 mm at a 40° wedge angle.

Any V-belt of section 13 (A) with datum length 1,135 mm is a drop-in replacement, regardless of brand. Key design data: minimum recommended pulley datum diameter 71 mm; weight 0.109 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).
