How KWIK-LAG Works
KWIK-LAG replaceable pulley lagging is constructed of
quality elastomer pads, hot vulcanized under high pressure
to metal backing plates that are factory formed to fit the
pulley face. The completed pad is attached to the pulley
shell by means of fasteners applied through the center of
the pad into the pulley. The fastener head is safely out of
the way of belt contact due to the recessed design of the
pad center (Figure 1). Pads will essentially cover the pulley
surface if the pulley diameter is in “whole inches”, i.e., 4″,
5″ and 8″. For fractional diameters, the pads will be
spaced slightly, the actual spacing to be determined by the
diameter involved.
KWIK-LAG is available in a wide range of elastomers,
backing plate metals and fastening methods to fill virtually
any lagging need. It may also be ordered with pad
thicknesses greater than the standard 1/4″ — up to 1/2″
maximum overall gauge — and is adaptable to any pulley
face width.
How to order KWIK-LAG
Pre-Installed On New Pulleys
Light-Duty conveyor and elevator pulleys can be purchased with KWIK-LAG pre-installed from a pulley manufacturer, conveyor equipment OEM, or an
authorized HOLZ RUBBER distributor. Simply specify KWIK-LAG when ordering. As an option, the new pulley may be purchased separately and KWIK-LAG installed at the jobsite.
For On-Site Installation On New Or Used Pulleys
A) Butt seam method – using 48″ pads, wherein maximum use is made of all material; however, pieces shorter than 2″ without two full fastener slots will be unusable.
The number of 48″ pads required for butt seam application on most common pulley diameters can be obtained from Table A below. However, KWIK-LAG can be factory formed to any diameter and installed using published installation procedures. For diameters not shown, use the formula for quantity selections. For pulley face widths not shown, use the next larger width or use the formula to calculate requirements.
B) Full width method – with pads cut to exact pulley face width, no butt seams. When no butt seams are desired, the number of 48″ pads required would depend entirely on the pulley and the quantity of face-width lengths which can be cut from one 48″ pad. In Example 1, five pads would be needed; in Example 2, two pads would be needed. Pulleys over 48″ wide must use butt seams.
