Standard Miether Bearing Protector Seals
A misapplied seal can actually diminish bearing life, leading to premature equipment failure and costly repairs. Applied properly, a bearing seal will extend bearing life and save money by reducing downtime and maximizing uptime. Bearing seals range from a simple seal ring (LER) design to both advanced-contacting and non-contacting type sealing arrangements.
A proper seal will surround the shaft, retain lubricant internal to the bearing assembly, and exclude foreign debris from the housing.
Miether provides a variety of seals to accommodate the split pillow block SAF series, solid pillow block MMW series, and flange cartridge block FCL/FCS series housings. They are available in fractional and metric dimensions, and can be customized for special applications. Materials of construction for hard parts are typically steel, aluminum, and stainless steel. Soft parts are made from Buna N and Viton.
