Overview
The Dodge SAF-XT 517 spherical roller bearing is an advanced pillow block housing engineered to optimize load-carrying capability in demanding industrial environments. Built on proven SAF-style dimensioning, the SAF-XT series offsets a standard spherical roller bearing to enhance performance over conventional USAF designs. Model 42119 delivers reliable shaft support for conveyor systems, bulk material handling, and mechanical power transmission applications where misalignment tolerance and sealed protection are critical.
Key Features
- Optimized Load Carrying: SAF-XT housing geometry increases dynamic and static load capacity compared to standard SAF housings
- Enhanced Sealing System: Grease relief channels and self-centering positive contact seal reduce contamination ingress in hostile environments
- Single Grease Fitting: Simplified lubrication design with improved grease purging for extended bearing life
- Cast Iron Housing: Durable construction suitable for outdoor and abrasive-exposure applications
- SAF Dimensional Interchangeability: Four-bolt cap design with elongated bolt holes and dimpled feet for easy retrofit into existing installations
- Misalignment Tolerance: Spherical roller bearing accommodates shaft deflection and housing misalignment typical of real-world installations
Technical Specifications
The Dodge SAF-XT 517 is designed to house standard 22200-series spherical roller bearings. Cast iron construction provides robust mounting for two-bolt or four-bolt pillow block configurations. Housing incorporates triple-lip contact seal with self-centering geometry and grease relief channels for optimal purging and relubrication. Maximum bearing speed capability is rated at 2200 rpm under standard operating conditions.
Typical Applications
- Conveyor system tail and bend pulleys
- Bulk material handling—grain, mining, aggregate transfer
- Package handling and sortation lines
- General industrial machinery shaft support
- Applications requiring sealed bearing protection in dusty or wet environments
