In 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 journals.

In contrast, POBCO-B 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-B material without adversely affecting the bearings' performance. These factors allow POBCO-B to handle a wide variety of materials on this equipment.

POBCO-B 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-B bearings and the elimination of excessive shaft wear are major factors in reducing high maintenance costs and periodic shutdowns.

POBCO-B 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.
