Pillow Block Bearings
Pillow block bearing units include a hollow set screw for easy and firm attachment on a shaft and a one-piece housing for structural strength. Grease nipples and holes supply lubricating grease to the bearing and maintain the flow of grease to balls and raceways. Rubber seals located between the inner and outer rings prevent lubricants from leaking and protect against contaminants.
Pillow block bearing units provide stability and self-alignment for many different applications. Adjustment of a misaligned shaft can occur in any direction and allows centering and alignment without distorting seals.
