SD055CP0 Bearing Product Overview & Core Advantages

The SD055CP0 is a **Reali-Slim Stainless Steel Bearing** engineered for applications demanding compact cross-sections and high precision. As a **thin section bearing**, it provides a significant weight and space savings without sacrificing performance. Its **single row** construction and **open seal type** make it ideal for **radial load** applications where maximum speed and minimal friction are critical. Manufactured entirely from **stainless steel** components with a **brass cage**, it offers excellent corrosion resistance and reliable operation. The bearing is pre-**lubricated** and adheres to **ABEC-1** precision tolerances, ensuring consistent performance and long service life in demanding environments.

SD055CP0 Bearing Model Code Explained, Specifications & Naming Convention

The model number SD055CP0 can be broken down to reveal its key technical specifications:

SD: Indicates the "Reali-Slim" series of thin section bearings.
055: Specifies the nominal bore diameter of 5.5 inches.
C: Denotes the radial internal clearance group.
P: Signifies that the bearing is supplied with a standard pre-lubricant.
0: Represents the specific series and cross-section design (0.5" width).

SD055CP0 Bearing Structural Features & Performance Benefits

The design of the SD055CP0 delivers distinct performance advantages. Its **thin section** profile is the primary feature, enabling compact and lightweight machinery designs. The use of **stainless steel** for both rings and balls provides superior **corrosion resistance**, making it suitable for harsh environments, including those requiring washdown or exposure to certain chemicals. The **brass cage** ensures smooth operation and stability at moderate speeds. With a **radial dynamic load rating of 2063 lbf** and a **radial static load rating of 4100 lbf**, it offers reliable support for significant **radial loads**. The **ABEC-1** tolerance class guarantees a high degree of running accuracy for smooth and precise rotation.

SD055CP0 Bearing Typical Application Areas

This **thin section bearing** is ideally suited for a wide range of precision equipment where space and weight are at a premium. Common applications include:

Robotics: Joints and actuators.
Aerospace & Defense: Guidance systems, control mechanisms, and instrumentation.
Medical Equipment: Scanners, centrifuges, and surgical robots.
Semiconductor Manufacturing: Wafer handling and positioning stages.
Optical and Imaging Systems: Rotary stages and mirror mounts.
