SB042XP0 Bearing Product Overview & Core Advantages
The SB042XP0 is a high-performance Four Point Contact ball bearing engineered for thin section applications requiring maximum load capacity in a minimal cross-section. Manufactured from stainless steel with a brass cage, it is designed to handle significant combined loads (radial, axial, and moment loads) simultaneously. Its ABEC-1 precision and corrosion-resistant construction make it an ideal solution for high-rigidity and high-reliability applications where space and weight are critical constraints.

SB042XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The unique raceway geometry allows a single row of balls to support substantial radial loads, axial loads in both directions, and moment loads efficiently, eliminating the need for complex bearing arrangements.
Thin Section & High Load Capacity: Despite its slim 0.3125" width and compact cross-section, the bearing offers impressive dynamic and static load ratings (1120 lbf radial dynamic, 1780 lbf axial dynamic), providing exceptional load density.
Precision & Rigidity: Built to ABEC-1 tolerance standards with tight internal clearance (0.0000 – 0.0005"), it ensures smooth, precise operation and contributes to overall system stiffness and accuracy.
Corrosion Resistance & Durability: The stainless steel rings and balls, combined with a brass cage, provide excellent corrosion resistance and reliable performance in harsh environments, with a broad operating temperature range from -30°C to 110°C.
SB042XP0 Bearing Typical Application Areas
The SB042XP0 is ideally suited for applications demanding a compact, lightweight design with high load-carrying capability. Key industries and equipment include:
- Robotics and Automation (Robotic arms, rotary joints)
- Aerospace and Defense (Gimbals, control mechanisms)
- Medical Equipment (CT scanners, surgical robots)
- Semiconductor Manufacturing (Wafer handling robots, precision stages)
- Optical and Instrumentation Systems (Rotary tables, positioning devices)
