Product Description The PB1-500-B combines the Spyraflo Self-Aligning SAE-840 Bronze bearing with their sintered aluminum Pillow-Block housing. The final assembly offers design engineers a Pillow-Block that is lightweight, has clean lines, dimensional consistency and is corrosion resistance. Oil impregnated bronze bearings are an economic solution for medium load / medium speed applications. Manufactured to SAE-840 specifications; containing 25% oil within the porous bronze spherical insert ensuring long, maintenance free, bearing life. Oil is distributed to the mounting surface by a hydrodynamic action, ensuring a protective film of lubricating oil is maintained between the bearing and mounting shaft. The Self-aligning bronze bearing is very securely mounted into the Aluminum Pillow-Block housing. Spyraflo Pillow-Blocks are often able to replace more expensive, larger and heavier cast-iron ball bearing assemblies. The profile and performance of Spyraflo Pillow-Blocks make them a very cost effective alternative to traditional Pillow-Block mounting challenges. Military Vehicles, Playground Equipment, Conveyors, Packaging Machines, Lawn Care Equipment, Loading Platforms and Radar Equipment are among the wide cross-section of applications benefiting from productivity and performance gains from Spyraflo Pillow-Blocks. In addition the Spyraflo Pillow-Block range can be used as a drop-in replacement for the Bunting Lube-Align product.
