SF042XP0 Bearing Product Overview & Core Advantages
The SF042XP0 is a Reali-Slim Stainless Steel bearing designed for applications requiring thin-section bearings with exceptional performance. This four-point contact ball bearing is engineered to handle combined radial and axial loads simultaneously, making it ideal for space-constrained, high-precision assemblies. Its stainless steel construction provides excellent corrosion resistance, while the ABEC-1 precision ensures reliable operation in demanding environments. The compact cross-section (0.75" width) offers significant weight savings without compromising load capacity.
SF042XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| SF042 | Reali-Slim series designation with 4.25" bore diameter | Standardized thin-section bearing series |
| XP0 | Specific internal design and clearance configuration | Optimized for precision applications |
SF042XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: Enables the bearing to support substantial combined radial and axial loads from any direction, with exceptional axial static load capacity of 14,110 lbf.
Thin-Section Construction: The compact 0.75" width and optimized cross-section provide significant space and weight savings while maintaining structural integrity.
Premium Material Selection: Stainless steel rings and balls with brass cage deliver excellent corrosion resistance and dimensional stability across the operating temperature range (-30°C to 110°C).
Precision Engineering: ABEC-1 tolerance class and tight radial internal clearance (0.0000 – 0.0005") ensure smooth, precise operation with minimal runout.
High Load Capacity: Exceptional dynamic load moment rating (8,993 lbf) and static load moment rating (14,110 lbf) for demanding applications.
