Overview
The Dodge 123809 P2B-SC-103 is a two-bolt pillow block ball bearing designed for standard-duty industrial applications. This 206 series non-expansion bearing features a 1-3/16 inch bore diameter, 4-1/4 to 5 inch bolt center-to-center length, and accommodates loads up to 4,368 lb dynamic and 2,538 lb static. The pillow block design provides excellent support and alignment for rotating shafts while minimizing vibration and wear, with set screw locking ensuring a firm grip on the shaft and preventing slippage.
Key Features
- Set Screw Shaft Attachment: Engineered with a 65 degree set screw angle, which ensures maximum grip onto the shaft. The most common means of securing a mounted ball bearing to a shaft, and also the easiest to install.
- Single Lip Contact Seal: Single lip seal design suitable for normal duty applications and non-expansion bearing construction for fixed applications.
- Cast Iron Housing: Durable material construction built for industrial environments and continuous operation.
- Powder Coated Finish: Steel powder coated construction for enhanced durability and corrosion resistance.
