52228 Bearing Product Overview & Core Advantages
The 52228 is a metric thrust ball bearing engineered for applications requiring high axial load capacity and precision. This thrust bearing is designed to accommodate unidirectional axial loads exclusively, making it an ideal solution for heavy-duty thrust applications. Its robust construction from high-grade chrome steel ensures exceptional durability and performance in demanding environments. The bearing features an open design, facilitating easier lubrication and maintenance, and is characterized by its high axial dynamic and static load ratings, providing reliable operation under significant thrust forces.
52228 Bearing Model Code Explained, Specifications & Naming Convention
The model number 52228 follows a standard thrust bearing designation. A breakdown of its key characteristics is provided below:
- 52: Indicates a thrust ball bearing series with a flat housing washer and shaft washer.
- 2: Refers to the dimensional series, relating to the cross-section.
- 28: Specifies the bore diameter in millimeters multiplied by 5 (28 * 5 = 140 mm). Please note the provided bore diameter is 120mm; the 52228 is a standardized code and the actual dimensions are as per the specification table.
- Open Seal Type: The absence of a suffix indicates an open (unsealed) design, allowing for custom lubrication schemes.
52228 Bearing Structural Features & Performance Benefits
- High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers a high axial dynamic load rating of 48,600 lbf and an exceptional axial static load rating of 150,750 lbf, enabling it to withstand intense thrust forces.
- Precision & Rigidity: The bearing features tight dimensional tolerances on the bore, outside diameter, and width, ensuring precise location and stable operation within an assembly.
- Durability & Corrosion Resistance: The inclusion of a stainless steel cage enhances the bearing's durability and provides better resistance to corrosion, contributing to a longer service life.
- Operational Versatility: With a temperature range of -30°C to 110°C, this bearing is suitable for a wide array of industrial environments.
