JB040XP0 Bearing Product Overview & Core Advantages
The JB040XP0 is a high-performance thin section sealed bearing designed for applications requiring compact design and precise motion control. This four-point contact ball bearing excels at simultaneously handling combined radial and axial loads from any direction. Manufactured to ABEC-1 precision standards with sealed construction and factory lubrication, it delivers reliable performance in space-constrained industrial applications demanding high positional accuracy and minimal maintenance.
JB040XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| JB040XP0 | Reali-Slim series sealed bearing with 4" bore diameter |
| Sealed Construction | Integrated seals for contamination protection and lubricant retention |
| Four Point Contact | Optimized raceway geometry for combined load capacity |
JB040XP0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With a cross-section of just 0.3125", this bearing provides maximum performance in minimal space, enabling compact machinery design while maintaining high load capacity.
Four-Point Contact Raceway: The optimized raceway geometry allows the bearing to handle combined radial and axial loads efficiently, with exceptional moment load capacity (Static: 3770 lbf, Dynamic: 1764 lbf).
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore tolerance: -0.0008"–0"), ensuring smooth operation and precise positioning.
Sealed & Lubricated: Factory-sealed construction with pre-applied lubricant provides maintenance-free operation and protects against contamination in demanding environments.
Premium Materials: Constructed with chrome steel rings and balls with brass cage for durability, corrosion resistance, and reliable performance across the operating temperature range (-30°C to 110°C).
