SB040XP0 Bearing Product Overview & Core Advantages
The SB040XP0 is a high-performance **Four Point Contact Ball Bearing** from the **Reali-Slim Stainless Steel Bearings** series, designed for applications requiring extreme thin cross-sections without compromising load capacity. This **inch-series bearing** features a 4" bore and compact 0.3125" width, making it ideal for space-constrained, high-precision assemblies. Its **stainless steel construction** provides excellent corrosion resistance, while the **four-point contact design** enables it to simultaneously support significant **combined radial and axial loads**, including moment loads, in a single, compact unit. This makes it a superior choice for applications demanding **high rigidity** and precise motion control.

SB040XP0 Bearing Structural Features & Performance Benefits
The SB040XP0's performance stems from its optimized design. The Four Point Contact raceway geometry allows a single row of balls to support combined loads effectively, simplifying assembly and reducing weight. The use of Stainless Steel for both rings and balls ensures high corrosion resistance, suitable for harsh environments. The Brass Cage provides excellent durability and guidance for the balls, contributing to smooth operation. With a Radial Dynamic Load Rating of 1091 lbf and a high Axial Static Load Rating of 4370 lbf, this bearing offers robust performance in a slim profile. The ABEC-1 precision class guarantees consistent running accuracy for reliable operation.
SB040XP0 Bearing Typical Application Areas
- Robotics: Rotary joints and actuator arms where space and weight are critical.
- Aerospace & Defense: Guidance systems, gimbals, and control surfaces.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic devices requiring corrosion resistance.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
