OPTIBELT C138 Ummantelte Keilriemen

OPTIBELT C138 — a wrapped V-belt, section 22 (C) to DIN 2215 / ISO 4184, for friction power transmission between two pulleys. All three length datums at a glance: inside length Li 3,505 mm, datum length Ld 3,563 mm, outside length La 3,593 mm. When cross-referencing other brands, always compare the same length datum. The cross-section measures 22 × 14 mm at a 40° wedge angle.

Any V-belt of section 22 (C) with datum length 3,563 mm is a drop-in replacement, regardless of brand. Key design data: minimum recommended pulley datum diameter 180 mm; weight 0.324 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 +80 °C. Optibelt manufactures to the S=C Plus (SetConstant) length concept — an advantage when several belts run side by side.
