6028 Bearing Product Overview & Core Advantages
The 6028 is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. Engineered to primarily accommodate radial loads, this bearing features an open design that facilitates high-speed operation. Manufactured to a P6 tolerance class, it ensures high running accuracy and is characterized by its robust construction, utilizing high-grade chrome steel for both rings and balls. Its combination of high radial dynamic load rating and superior dimensional stability makes it a reliable choice for precision machinery.
6028 Bearing Model Code Explained, Specifications & Naming Convention
| Code | Interpretation | Technical Significance |
|---|---|---|
| 60 | Series Designation | Indicates a deep groove ball bearing with a standard width series. |
| 28 | Bore Diameter Code | Specifies a 140 mm bore diameter. |
| (Open) | Seal Type | No seals or shields, allowing for higher limiting speeds and easy relubrication. |
| P6 | Tolerance Class | Denotes a precision bearing with tighter dimensional and running accuracy tolerances than standard P0 class. |
| CN | Radial Internal Clearance | Standard normal clearance group, suitable for most common operating conditions. |
6028 Bearing Structural Features & Performance Benefits
The performance of the 6028 bearing is derived from its fundamental deep groove ball bearing design. The uninterrupted raceways and optimized ball complement enable it to handle significant radial loads efficiently. The open construction is critical for achieving a high limiting speed of 4,000 rpm, as it minimizes friction and heat generation. The use of high-purity chrome steel ensures high hardness and durability, contributing to a long operational lifespan. Its P6 tolerance guarantees precise running, reducing vibration and noise in sensitive applications. The specified bearing dimensions (140mm bore, 210mm OD, 33mm width) and tight dimensional tolerances ensure reliable interchangeability and fit.
6028 Bearing Typical Application Areas
The 6028 precision bearing is ideally suited for a wide range of industrial machinery requiring high-speed and high-accuracy performance. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmission Systems
- Machine Tool Spindles and Precision Machinery
- Pumps and Compressors
- Material Handling Equipment
