Overview
The Sealmaster SFT-12TC 3/4″ flange mount bearing is a robust, standard-duty industrial bearing designed for reliable power transmission in machinery and equipment. Built with cast iron construction and a deep-groove ball bearing cartridge insert, this unit delivers proven performance in moderate radial load applications. The two-bolt flange design enables straightforward installation on perpendicular mounting surfaces, making it ideal for conveyors, fans, blowers, and processing equipment.
Key Features
- Cast Iron Housing: Solid construction for rigidity, vibration damping, and long service life
- Deep-Groove Ball Bearing Insert: Rated standard duty for moderate radial loads and light-to-moderate thrust loads
- Two-Bolt Flange Mount: Compact 2-bolt configuration with machined foot pads for precise alignment and stability
- Skwezloc Locking Collar: Fluoropolymer-coated concentric clamp collar with Torx head cap screws provides 360-degree holding power without marring the shaft
- Contact Seals (SFT-12TC): Nitrile rubber single-lip seals on both sides retain factory-applied lubricant and exclude contaminants
- Pin-and-Dimple Anti-Rotation System: Exclusive Sealmaster design prevents outer-ring rotation within the housing, reducing heat buildup and extending bearing life
- Self-Aligning Design: Convex sphered outer surface compensates for minor shaft misalignments (±2 degrees)
- Regreasable: Grease fitting on outer surface allows convenient relubrication during service
