This Don Dye line of heavy duty double row ball bearing
flat, flanged, and V groove idlers was developed to
handle heavier loads that exceed the capacity of single
row ball bearing idlers. The double row idlers are
more stable when side loads or off center loads occur.
They are
available with 3/8", 1/2", 5/8" and 3/4" bolt mounting.
These riveted idlers are constructed from 13 gauge
material. The high quality precision bearings made of
52100 bearing steel are pre-lubricated, have contact
type seals for retention of high temperature lubricant
to ensure protection against dust, dirt or other foreign
matter. No re-lubrication is required. A compression
ring is compressed between center of O.D. of bearing and
center I.D. of pulley bearing pocket to assure a firm
reliable fit of pulley more evenly to the outer bearing
race resulting in minimum distortion of bearing O.D,
(USA patent 4518372 foreign patents pending). Our tests
have proven this method of bearing installation to give
longer and more reliable bearing life.
