DIMENSIONS

PRODUCT DESCRIPTION PRODUCT CODE WIDTH THICKNESS STANDARD ROLL LENGTH WEIGHT/lm
Polyurethane lagging 12mm ELA-PU-PLN-N-12 249mm-251mm 11mm-12mm 58.2m 3.70kg
Polyurethane lagging 20mm ELA-PU-PLN-N-20 249mm-251mm 19mm-20mm 35.0m 6.39kg

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

Example: 12 mm 58.2m roll product code: ELA-PU-PLN-N-12-58200
15 mm 1.2m strip product code: ELA-PU-PLN-N-20-01200

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.
