Sealmaster SF-20T Gold Line Four-Bolt Flange Bearing

Sealmaster SF-20T Gold Line Four-Bolt Flange Bearing is a mounted ball bearing unit housed in rugged cast iron designed for heavy, vibrating, and shock loads. It features a 1-1/4" bore and a four-bolt flange with a round piloted surface, delivering precise alignment and secure mounting. The Gold Line design employs a wide inner race with Skwezloc concentric locking for near-perfect runout, a felt labyrinth seal and flinger for dry and dusty environments, and a land-riding retainer that promotes 360° grease circulation around the rolling elements for improved lubrication retention. The bearing insert is 52100 bearing steel with a black oxide finish, and a lock pin with a dimple provides direct lubrication access and anti-rotation protection.
