6208 Y/C78 Bearing Product Overview & Core Advantages
The 6208 is a single row deep groove ball bearing designed for exceptional performance in a wide range of industrial applications. As a metric bearing with an open design, it excels at handling radial loads primarily, while also accommodating moderate axial loads in both directions. Its key advantages include high operational reliability, a broad temperature range from -30°C to 120°C, and compliance with ROHS and REACH standards, making it a versatile and robust choice for standard-duty machinery and equipment.
6208 Y/C78 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6208 follows a standard industry designation. Here is a breakdown of its key characteristics:
- 6: Indicates the series, a "Medium" series deep groove ball bearing.
- 2: Represents the width series.
- 08: Signifies a bore diameter of 40 mm (08 * 5 = 40 mm).
- Open (No Seal/Shield Suffix): The absence of a suffix like "2Z" or "RS" denotes an open bearing, allowing for higher limiting speeds and custom lubrication regimes.
- No Lubrication Suffix: Supplied without factory grease (Lubrication: None), providing flexibility for the user to apply a lubricant suitable for the specific application.
6208 Y/C78 Bearing Structural Features & Performance Benefits
The 6208's performance is derived from its fundamental deep groove ball bearing construction:
- High-Speed Capability: The open design and absence of contact seals minimize friction and heat generation, enabling a high limiting speed of 8,300 rpm.
- Robust Load Capacity: Manufactured entirely from Chrome Steel for the rings, balls, and cage, it offers a high radial dynamic load rating of 6542 lbf and a radial static load rating of 4002 lbf, ensuring long service life under demanding conditions.
- Standard Precision: Built to ABEC 1 | ISO P0 tolerance class and standard radial internal clearance (CN), it provides reliable and consistent performance for the vast majority of industrial applications without the need for high-precision costs.
- Versatile Mounting: The precise dimensional tolerances on the bore diameter, outside diameter, and width facilitate easy installation and interchangeability.
6208 Y/C78 Bearing Typical Application Areas
The 6208 is a workhorse component found in numerous sectors due to its balanced performance and reliability. Common applications include:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
