SD040CP0 Bearing Product Overview & Core Advantages

The SD040CP0 is a thin section bearing from the Reali-Slim Stainless Steel Bearings series, designed for applications requiring compact, lightweight solutions without sacrificing performance. This single row ball bearing features an open design and is precision-manufactured to ABEC-1 tolerance standards, ensuring reliable operation. Its all-stainless steel construction (rings and balls) provides excellent corrosion resistance, making it suitable for harsh environments. The bearing is pre-lubricated and optimized to handle radial loads efficiently, offering a high static load capacity of 3080 lbf in a minimal cross-section.

SD040CP0 Bearing Model Code Explained, Specifications & Naming Convention

Code Segment Technical Meaning
SD Indicates the Reali-Slim series with a specific thin-section design.
040 Specifies the bore diameter in inches (4").
C Denotes the cross-section size (0.5" width).
P Identifies the bearing as having an open seal type (unshielded).
0 Typically indicates a standard radial internal clearance and standard cage (brass).

SD040CP0 Bearing Structural Features & Performance Benefits

The SD040CP0's design centers on its thin section construction, which minimizes weight and space requirements while maintaining structural integrity. The single row of balls, combined with a brass cage, ensures smooth rotation and stable operation under radial dynamic loads up to 1755 lbf. The use of stainless steel for both rings and balls provides superior corrosion resistance and enables operation across a broad temperature range from -30°C to 110°C. The ABEC-1 precision and controlled radial internal clearance (0.0000 – 0.0005") contribute to consistent performance and reduced vibration in precision assemblies.

SD040CP0 Bearing Typical Application Areas

  • Aerospace & Defense: Gimbal systems, control mechanisms, and instrumentation where weight savings and reliability are critical.
  • Robotics: Joints and rotary actuators in robotic arms requiring compact, high-capacity bearings.
  • Medical Equipment: Scanning devices, surgical robots, and diagnostic instruments benefiting from corrosion-resistant, precision components.
  • Semiconductor Manufacturing: Precision stages and wafer handling equipment where clean, reliable motion is essential.
  • Optical & Positioning Systems: Rotary tables and mirror mounts requiring minimal deflection and high accuracy.
