Twin Plain Linear Bearing Pillow Block - PW04C 1/4″ Closed, Self-Aligning, Compensated

Twin plain linear bearing pillow block, closed, with a 1/4" compensated ID. This self-aligning mountable aluminum alloy pillow block bearing features an inserted Simplicity® plain bearing with a bonded, self-lubricating FrelonGOLD® liner for oil-free, maintenance-free motion through high temperatures, dirt, contamination, vibration, and shock loads. The twin body adds bearing surface, shaft support, and load-carrying capacity. For self-alignment, the inserted bearing can tilt slightly within the housing, compensating for up to 1/2° misalignment from centerline in all directions and helping reduce binding from minor shaft deflection or parallel shaft misalignment. Eight pre-positioned mounting holes allow direct fastening to machinery or support structures.

• Closed shell for use on end-supported round shafts
