SG180XP0 Bearing Product Overview & Core Advantages
The SG180XP0 is a high-performance Four Point Contact Ball Bearing engineered for demanding applications requiring exceptional precision and reliability. As part of the Reali-Slim Stainless Steel Bearings series, this single row bearing features a thin cross-section design that delivers a superior weight-to-load capacity ratio. Its four point contact geometry enables it to simultaneously support high radial loads, axial loads in both directions, and significant moment loads, making it an ideal solution for compact, high-rigidity systems. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and smooth operation.

SG180XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry creates four distinct contact points between the balls and raceways. This design provides exceptional stiffness and enables the bearing to handle combined loads (radial, axial, and moment) efficiently in a single, compact unit, simplifying system design.
Thin-Section Construction: With a consistent 1" cross-section, this bearing offers significant space and weight savings without compromising on load capacity. The large bore diameter relative to the outer diameter is ideal for applications where a large shaft must pass through a confined space.
Premium Material Selection: The use of stainless steel for all bearing components ensures excellent corrosion resistance, making it suitable for harsh environments. The brass cage provides superior strength and guidance at high rotational speeds.
High Load Ratings: Engineered for durability, the SG180XP0 boasts impressive dynamic and static load ratings (16,386 lbf radial dynamic, 27,410 lbf axial dynamic, and a 116,793 lbf dynamic load moment), ensuring long service life under heavy loads.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with controlled radial internal clearance, this bearing delivers smooth, low-vibration, and precise operation.
SG180XP0 Bearing Typical Application Areas
- Robotics: Robotic arms and joints requiring high moment load capacity and compact design.
- Aerospace & Defense: Actuators, radar platforms, and gimbal systems where precision and reliability are critical.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Medical Equipment: CT scanners, MRI machines, and surgical robots.
- Industrial Automation: Rotary tables, indexing heads, and precision gearboxes.
