Spindles Lengths

Extension spindles are supplied as whole pieces in lengths up to 5 meters.For lengths greater than 5 meters, the spindles are supplied in two or

more sections, joined by spindle collars.IMPORTANTE: As wire drawn iron is flexible, the use of intermediaryguide bearings are recommended at intervals of 2 meters maximum(spindle 1 1/8") or 3 meters (spindle 1 3/4", 2", 2 1/2" and 2 5/8'').

Coating

Epoxy polyamide paint.

Intermediary Bearings

Intermediary bearings, manufactured in ductile iron, are used to guideextension spindles.

Ob.: To avoid bending, the bearings should be installed every 2 meters for1 1/8" spindles, and every 3 meters for greater diameter spindles.
