Dodge(Baldor) 129179 Pillow Block

The Dodge (Baldor) 129179 is a high-performance normal duty 2-bolt pillow block bearing engineered for precision and reliability in HVAC and industrial power transmission systems. Featuring a 1.6875-inch (1-11/16") bore diameter, this unit utilizes the Grip-Tight adapter locking system (P2B-GTAH-111). This mechanism provides 360-degree concentric contact with the shaft, significantly reducing vibration and preventing the shaft marring often caused by traditional setscrews. The 209 Series housing is constructed from rugged cast iron, providing a rigid foundation that maintains alignment under varying thermal and mechanical stress.

Designed for non-expansion (fixed) applications, the Dodge 129179 pillow block manages a dynamic load capacity of 7,891 lbs and a static load of 4,906 lbs. It is equipped with advanced single lip seals to protect the internal rolling elements from contaminants. With a maximum rated speed of 8,000 RPM, this shaft-mounted bearing is an ideal solution for contractors looking to optimize uptime in commercial air handling units or conveyor drives. The housing dimensions follow industry standards, featuring a bolt center-to-center range of 5.5 to 6.19 inches and a 2.13-inch base-to-center height for seamless interchangeability.

• Grip-Tight Adapter Mounting: Ensures full concentric contact for 360-degree grip, reducing system-induced vibration and shaft fatigue.
• High-Speed Capacity: Optimized for performance up to 8,000 RPM, making it suitable for high-demand fan and blower applications.
• Rugged Cast Iron Housing: Provides superior structural integrity and heat dissipation compared to lighter-duty alternatives.
• Thin Wall Adapter: Allows for easy installation on commercial grade shafting while acting as a built-in bearing puller for simplified removal.
• Relubricatable Design: Standard grease fitting allows for consistent maintenance to extend service life in dusty or humid environments.

Is the Dodge 129179 compatible with undersized shafting?
Yes, the Grip-Tight adapter system is designed to accommodate commercial-grade and slightly undersized shafting while maintaining a secure, concentric fit.

What is the difference between this and a standard setscrew pillow block?
Unlike setscrews that bite into the shaft at specific points, the 129179 uses an adapter sleeve that grips the shaft uniformly, preventing fretting corrosion and surface damage.

Can this unit be converted to an expansion-type bearing?
The 129179 is typically supplied as a non-expansion (fixed) unit. For expansion requirements, a different housing or internal configuration may be necessary to allow axial movement.
