SealMaster MP-55 Pillow Block Bearing Gen Gold Set Screw

The SealMaster MP-55 pillow block bearing is a Gold Line, two-bolt, set-screw mounted unit designed for a 3-7/16 in shaft. Its cast iron housing features an extended inner ring and a land-riding retainer design that promotes 360-degree grease circulation around the rolling elements and improved lubrication retention, while diamond-faceted setscrews positioned at 120° secure the inner race for even clamping. A felt labyrinth seal provides basic containment, and an exclusive lock pin and dimple support direct lubrication and anti-rotation. Key specs include a 3-7/16 in bore, approximately 9.88 in width, and a 4 in shaft height, with a solid base and standard mounted ball bearing configuration. This combination delivers reliable support for mid-range loads in machinery where stable alignment and durable casing are important.
