634-2Z Bearing Product Overview & Core Advantages
The 634-2Z is a metric single row deep groove ball bearing designed for high-performance applications requiring compact design and reliable operation. This shielded bearing excels in handling substantial radial loads while offering moderate axial load capacity. Its precision P6 tolerance class and optimized internal geometry ensure smooth, quiet running and enhanced operational accuracy. Pre-lubricated with grease and featuring integral steel shields, the 634-2Z is engineered for long service life and minimal maintenance in demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 634 | Standard series designation for a deep groove ball bearing with 4mm bore, 16mm OD, and 5mm width. | Defines core bearing dimensions and interchangeability. |
| -2Z | Bearing is equipped with steel shields on both sides. | Provides effective contaminant protection, retaining lubricant and excluding dust and debris, making it suitable for maintenance-free applications. |
634-2Z Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to a P6 tolerance class with a CN radial internal clearance, this bearing offers precise running accuracy and stable performance under load, contributing to overall system rigidity.
- Optimized Load Capacity: The single row deep groove raceway design is highly effective at carrying radial dynamic loads up to 250 lbf, with the capability to support combined loads.
- High-Speed Capability: The combination of a low-friction stainless steel cage, high-grade chrome steel components, and effective grease lubrication enables a limiting speed of 48,000 rpm.
- Maintenance-Free & Long-Lasting: The 2Z shields seal in the factory-applied grease, providing consistent lubrication and protection throughout the bearing's service life within its specified temperature range of -30°C to 120°C.
634-2Z Bearing Typical Application Areas
The 634-2Z is ideally suited for compact, high-speed mechanisms across various industries, including:
- Small Electric Motors: Used in fans, blowers, and precision drive systems.
- Office Automation Equipment: Critical components in printers, scanners, and copiers.
- Medical Devices: Found in small pumps, dental handpieces, and laboratory instrumentation.
- Precision Instruments: Supports spindles and guides in optical and measuring equipment.
