Sealmaster Gold Line MP-27 Pillow Block Bearing

The Sealmaster Gold Line MP-27 Pillow Block Bearing is a medium‑duty two‑bolt mounted bearing unit with a 1‑11/16 in (1.6875 in) bore built for MP Series installations, featuring a rugged cast‑iron housing with extended inner ring for stable alignment and a net weight of approximately 0.575 lb. Inside, a 52100 steel bearing insert with black oxide finish rides on a zone‑hardened inner ring and uses 120° diamond‑faceted setscrews for secure locking, while a standard felt labyrinth seal helps keep contaminants out. The Gold Line design emphasizes lubrication efficiency with a land‑riding retainer that enables 360° grease circulation around the rolling elements and a lock pin/dimple for direct lubrication and anti‑rotation, making it well suited for conveyors, fans, and other light‑to‑medium duty drives where reliable bearing support and easy maintenance matter.
