n general, bearing support
stations on screw conveyors must be classified as severe service. The
materials handled are often corrosive and abrasive and sometimes moisture
laden. Conditions are encountered that can disintegrate conventional
bearings in extremely short time while also scoring and pitting the
In contrast, POBCO hanger bearings are unaffected by most
corrosive materials and work well even under moist conditions. When
abrasive materials are being handled, the small amount of particles that
reach the bearing surface become embedded in the POBCO
material without adversely affecting the bearings' performance. These
factors allow POBCO to handle a wide variety of materials
on this equipment.
POBCO hanger bearings are self-lubricating for life. They
are ideal for installation in screw conveyor assemblies, where the
bearings are usually inaccessible. The long life of POBCO
bearings and the elimination of excessive shaft wear are major factors in
reducing high maintenance costs and periodic shutdowns.
POBCO bearings are the quietest bearings made for screw
conveyors, whether operating slowly or at an accelerated pace. They
eliminate the noisy metal-to-metal sounds inherent is such machinery
employing metal bearings. The hanger bearings listed are the most commonly
used. Non-cataloged hanger bearing sizes and shapes, including sizes
larger then those listed, are available.
