Overview
The Dodge SC-2-7/16 pillow block bearing is a 2-7/16-inch bore, two-bolt mounted ball bearing unit designed for general industrial machinery and power transmission systems. Manufactured to industry standards with cast iron housing, this bearing provides reliable radial load support with minimal friction in continuous-duty applications. The non-expansion design features a set screw locking collar and single-lip contact seal, making it ideal for fixed shaft alignment where bearing creep prevention is essential.
Key Features
- 2-Bolt Base Mount: Compact footprint for space-constrained installations
- Set Screw Locking: Secure collar attachment prevents unintended shaft rotation
- Single-Lip Seal: Protects against contamination while allowing easy lubrication access
- Cast Iron Housing: Durable construction rated for industrial environments and temperature ranges of 225–400°F
- Non-Expansion Bearing (Fixed): Maintains precise alignment in applications requiring zero endplay
- Grease Lubrication: Pre-filled with Unirex N2 grease; maintenance-free initial operation
