SA042XP0 Bearing Product Overview & Core Advantages
The SA042XP0 is a Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series, designed for applications demanding compact cross-sections and high precision. This thin section bearing is engineered to simultaneously support combined loads, including significant radial, axial, and moment loads, within a minimal space envelope. Its stainless steel construction offers excellent corrosion resistance, making it ideal for harsh environments. The bearing is pre-lubricated for immediate use and adheres to ABEC-1 precision tolerances, ensuring reliable performance in high-accuracy systems.
SA042XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SA | Indicates the bearing is from the Stainless Steel Reali-Slim series. |
| 042 | Specifies the nominal bore diameter in inches (4.25"). |
| X | Denotes a Four Point Contact ball bearing design. |
| P | Specifies the cross-section (width) code; "P" corresponds to a 0.25" width. |
| 0 | Indicates an Open (unsealed) construction. |
SA042XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single row of balls to efficiently support combined radial, axial, and moment loads, simplifying assembly and reducing the need for multiple bearing arrangements.
- High Load Capacity: Engineered to handle substantial dynamic and static load ratings (783 lbf radial dynamic, 1260 lbf axial dynamic) despite its thin cross-section, providing robust performance in compact spaces.
- Precision & Rigidity: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance, ensuring smooth operation, high running accuracy, and enhanced system rigidity.
- Corrosion Resistance & Longevity: Constructed entirely from stainless steel (rings and balls) with a brass cage, offering superior resistance to corrosion and enabling reliable operation in a wide temperature range from -30°C to 110°C.
- Lightweight & Compact: With a minimal cross-section (0.25" width) and low weight (0.2 lbs), it is ideal for applications where space and weight savings are critical.
