JB055XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: Enables the bearing to sustain combined radial and axial loads simultaneously from any direction, eliminating the need for multiple bearing arrangements.
Thin-Section Construction: With a consistent cross-section (0.3125" width across 5.5" bore), this design provides maximum space savings while maintaining structural integrity.
Sealed Protection: Integrated seals protect against contamination while retaining lubrication, ensuring consistent performance and extended service life.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with minimal radial internal clearance (0.0000-0.0005"), delivering predictable performance and smooth operation.
High Load Capacity: Rated for dynamic radial loads up to 1304 lbf and dynamic axial loads up to 2100 lbf, providing robust performance in demanding applications.
