PowerStrand 6x19 Class Bright Fibre Core Wire Ropes are ungalvanized and supplied with an A1 lube. The A1 lube is a light grease applied during the stranding and closing process to encapsulate the individual wires to reduce wear and slightly inhibit the onset of corrosion. Bright ropes should be periodically inspected & re-lubed to ensure wire to wire friction is reduced to extend service life.
Fibre core wire ropes are generally used for ropes where flexibility in handling is required. The fibre core is impregnated with lubricant before manufacture, it then continues as an internal lubricator during the operation of the rope. Fibre core ropes are not suitable where they are subject to crushing on drums and sheaves.
The Crosby Group manufactures Vitalife Wire Rope Lubricants that are specifically formulated for this purpose. It is available in Spray Cans and Liquid form. Click Here
