DIMENSIONS

PRODUCT DESCRIPTION PRODUCT CODE WIDTH THICKNESS STANDARD ROLL LENGTH WEIGHT/lm
Polyurethane lagging 12mm ELA-PU-PLN-N-12V 249mm-251mm 12.2mm-13.2mm 9.7m 4.21kg
Polyurethane lagging 20mm ELA-PU-PLN-N-20V 249mm-251mm 20.2mm-21.2mm 9.7m 6.90kg

Product code for different lengths: Add 5 digit number indicating length in mm.

Example: 12 mm 9.7m roll product code: ELA-PU-PLN-N-12V-09700
20 mm 1.2m strip product code: ELA-PU-PLN-N-20V-01200

For strips always allow 100 mm extra length over the pulley face width to have 50 mm at each end of overhang.

Thickness variation (all strips/pulley) +/-0.5mm

Polyurethane lagging with thickness > 15mm only recommended for pulleys with diameters over 400mm.
