Overview
The JAF 2204E-2RS1 self-aligning bearing is a double-row metric ball bearing designed for applications requiring shaft misalignment tolerance and reliable, low-friction operation. This sealed bearing combines precision engineering with maintenance-friendly construction, making it ideal for industrial automation, machinery, conveyors, and rotating equipment where alignment flexibility is critical.
Key Features
- Double-row self-aligning ball bearing construction allows accommodation of shaft misalignment without performance degradation
- Sealed on both sides with sheet-steel reinforced rubber (2RS) contact seals for protection against contaminants and moisture
- Low-friction design delivers efficient operation even at higher speeds with minimal frictional heat
- Cylindrical bore for direct shaft mounting
- Standard precision rating and normal radial internal clearance for general industrial applications
- New in box condition — factory sealed and ready for immediate deployment
