SA040XP0 Bearing Product Overview & Core Advantages
The SA040XP0 is a Four Point Contact thin section bearing designed for applications demanding high precision and space optimization. Manufactured entirely from stainless steel with a brass cage, this bearing offers excellent corrosion resistance and reliable performance. Its defining characteristic is its ability to support combined loads, including significant radial, axial, and moment loads simultaneously, making it an ideal solution for compact, high-rigidity assemblies. The ABEC-1 tolerance ensures consistent precision for a wide range of industrial applications.
SA040XP0 Bearing Model Code Explained, Specifications & Naming Convention
The SA040XP0 model number provides key technical specifications:
- SA: Indicates a Stainless Steel thin section bearing from the Reali-Slim® series.
- 040: Specifies the bore diameter of 4 inches.
- XP: Denotes the cross-section, here a 0.25" width ("X" Series).
- 0: Refers to the open (unsealed) construction and standard internal clearance.
SA040XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The single-row bearing geometry allows it to handle combined radial, axial, and moment loads efficiently in a very compact envelope, providing exceptional load capacity for its size.
- Thin Section Construction: With a consistent cross-section (0.25"), this bearing enables lightweight and space-saving designs without sacrificing performance, contributing to overall system high rigidity.
- Corrosion-Resistant Materials: The use of stainless steel for rings and balls, combined with a brass cage, ensures long-term reliability in harsh environments and resists corrosion.
- Precision Engineering: The ABEC-1 tolerance class and controlled radial internal clearance guarantee smooth operation and precise rotational accuracy.
SA040XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications where space is constrained and high load capacity is required. Key industries and equipment include:
- Robotics: Joints and rotary actuators.
- Aerospace & Defense: Gimbals, control mechanisms, and satellite components.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic devices.
- Semiconductor Manufacturing: Precision stages and wafer handling robots.
- Optical and Instrumentation Systems: Rotary tables and scanning mirrors.
