Product Overview and Core Advantages
The 692xzz is a miniature metric single row deep groove ball bearing designed for applications requiring compact dimensions and reliable performance. This shielded bearing excels in handling radial loads and is engineered for high-speed operation. Its primary advantages include a compact design (2.5 mm bore, 7 mm OD), making it ideal for space-constrained assemblies, and robust construction using chrome steel rings and balls for durability. The inclusion of stainless steel shields provides effective contamination protection, enhancing operational life in demanding environments.
692xzz Bearing Model Code Explained, Specifications & Naming Convention
The model number 692xzz is decoded as follows:
- 692: The basic series designation, indicating a miniature deep groove ball bearing with a 2.5 mm bore and 7 mm outside diameter.
- x: This placeholder typically indicates a specific internal design or series variant. In this context, it confirms the standard single-row deep groove construction.
- zz: Denotes that the bearing is shielded on both sides (non-contact). The shields, made of 300 Series Stainless Steel, protect the internal components from contaminants while allowing for high-speed operation with minimal friction.
Structural Features and Performance Benefits
The 692xzz's performance is a direct result of its precision engineering:
- High-Speed Capability: The combination of a stainless steel cage, precision-ground chrome steel components, and optimized internal geometry enables a high limiting speed of 63,000 rpm.
- Effective Sealing: The non-contact ZZ shields provide a robust barrier against dust and debris without significantly increasing rotational torque, which is critical for maintaining high-speed performance.
- Radial Load Capacity: With a dynamic load rating of 74 lbf and a static load rating of 23 lbf, this bearing offers reliable performance for its size class in various radial load applications.
- Precision and Stability: Manufactured to ABEC1 tolerance class with an MC3 radial internal clearance (0.002mm to 0.013mm), it ensures smooth, low-vibration operation, which is essential for precision instruments.
692xzz Bearing Typical Application Areas
The 692xzz miniature deep groove ball bearing is specified for a wide range of compact and high-speed devices, including:
- Small Precision Motors (e.g., in drones, RC models, and small fans)
- Medical and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Control Devices
- Computer Cooling Fans
Its compliance with ROHS and REACH standards makes it suitable for use in products with stringent environmental and safety requirements.
