SWR Z33.5 Ummantelte Keilriemen

The SWR Z33.5 is a wrapped V-belt in section 10 (Z) to DIN 2215 / ISO 4184, transmitting power by friction through its wedge flanks in the pulley groove. All three length datums at a glance: inside length Li 851 mm, datum length Ld 873 mm, outside length La 889 mm. When cross-referencing other brands, always compare the same length datum.

The cross-section measures 10 × 6 mm at a 40° wedge angle. Any V-belt of section 10 (Z) with datum length 873 mm is a drop-in replacement, regardless of brand. Key design data: minimum recommended pulley datum diameter 50 mm; weight 0.064 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).
