The stainless steel SF210 (stainless steel cast iron) pillow block can mount shafts with Φ50mm diameter. UCF pillow blocks have an UC210 stainless steel ball bearing installed. They are suggested for industrial and agricultural applications where normal loads are encountered. Compact, one-piece housing with two-bolt mounting can be installed in any position and makes bearing replacement easy. These units use wide inner ring ball bearings with self-aligning spherical outside diameters that compensate for shaft misalignment. Bearing is prelubricated and ready for immediate installation. Grease fitting is also supplied for relubrication. The bonded seal design is well-suited for applications involving wet or dirty environments. Bolt-hole spacing and base to center height dimensions are interchangeable with competitive units. Made in China .
