ROUGH TOP LAGGING
Rough Top Rubber Lagging is available in either
vulcanized
or
bolt on
.
Vulcanized Rough Top
is 60±5 durometer Shore A,
SBR Black Rubber. It is bonded directly to the pulley
rim in the vulcanizing process.
Bolt on Rough Top
Lagging material is applied to
the pulley rim which is coated with a special bonding
adhesive and fastened to the pulley rim with strong
self tapping screws at the beginning and end of the
lagging.
The top cover of both types of Rough top has thousand
of fingers that grip the belt. This irregular surface
increases the rubber’s tractive capacity and helps keep
the rubber clean.
SLIDE-LAG
®
Quality rubber is bonded to special traction pads fitting the
pulley rim. The pads slide into retainers welded into the pulley
rim. New pads can easily be replaced without removing the
pulley from the conveyor.

VULCANIZED RUBBER LAGGING
AND GROOVING
Vulcanized rubber lagging is 60±5 durometer Shore A,
S.B.R. black rubber without a cloth fabric. It is bonded
directly to the pulley rim in the vulcanizing process.
The finished rubber surface has a cloth impression.
When GROOVING is required, please specify whether
herringbone or another type of grooving is desired.
Normally, grooving should not be used in vulcanized
rubber less than
3
/
8
" thick.
NOTE:
Direction of grooving must be stated if we
supply the lagging and install a shaft. Normally
grooving should be run with the apex of the
pattern leading.
VULCANIZED LAGGING TOLERANCES
PLAIN WRAPPED CLOTH IMPRESSION LAGGING:
±
1
/
8
" on rubber thickness—no concentricity tolerance
guaranteed.
If you have an application for lagged pulleys that
demands exact concentricity, such as some elevator
pulleys, slide bed or reversing conveyor pulleys, then
we suggest that you order machined lagged pulleys.
True, this will cost more initially; however, in a tough
application, this cost would be offset quickly by
additional necessary labor when trying to train the
belt.
