Pillow Block Units
UCPX Series Wide Pillow Block Units
Cast iron pillow block using a wide-width (X-series) bearing insert for greater load capacity at the same shaft diameter without stepping up to the larger UCP3 housing footprint. A middle ground between the standard UCP2 and the physically larger UCP3 series.
