S682x Bearing Product Overview & Core Advantages
The S682x is a miniature deep groove ball bearing engineered for applications demanding compact size, reliable performance, and high rotational accuracy. As a single row bearing, it excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its small footprint, with a bore of just 2.5 mm and an outside diameter of 6 mm, makes it an ideal precision bearing for compact mechanisms requiring smooth, low-friction operation.
S682x Bearing Model Code Explained, Specifications & Naming Convention
The S682x model designation follows a standard industry format. Here is a breakdown of its key characteristics:
- S68: Denotes the bearing series, indicating a specific micro-size deep groove ball bearing design.
- 2: Indicates the bore diameter code. For this series, '2' corresponds to a 2.5 mm bore.
- x: The 'x' is a placeholder for any potential suffix codes that specify variations in seals, shields, internal clearance, or cage type. This particular variant is Open (no seal or shield).
Key specifications derived from the model and its data:
- Open: No contact seals, enabling higher limiting speeds and requiring external lubrication.
- Tolerance Class: ABEC1: Specifies standard precision grade for reliable performance.
- Radial Internal Clearance: MC3: A specific internal clearance group suitable for a wide range of applications.
S682x Bearing Structural Features & Performance Benefits
The S682x's design delivers distinct performance advantages in miniature applications:
- High-Speed Capability: The open design and optimized internal geometry, combined with a stainless steel cage, contribute to its high limiting speed of 63,900 rpm, making it a capable high-speed bearing for its size.
- Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, and cage), this bearing is well-suited for environments where moisture or mild chemicals are present, ensuring long-term reliability.
- Precision Operation: The ABEC1 tolerance class ensures consistent dimensional accuracy and smooth running, which is critical for reducing vibration and noise in precision instruments.
- Optimized Internal Geometry: With 8 precision balls of 0.8 mm diameter, the bearing provides a balanced load distribution and low rotational torque.
S682x Bearing Typical Application Areas
The compact size and reliable performance of the S682x miniature bearing make it suitable for a wide array of precision devices, including:
- Small DC Motors and Stepper Motors
- Medical Devices and Instrumentation
- Optical Encoders and Scanners
- Precision Gearboxes
- Small Fans and Impellers
