635zz Bearing Product Overview & Core Advantages
The 635zz is a metric single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its core advantages stem from its shielded construction, which provides effective protection against contamination while retaining lubrication. This bearing is engineered to handle primarily radial loads and is characterized by its compact design with a 5 mm bore, 19 mm outside diameter, and 6 mm width. Manufactured from high-grade chrome steel with a stainless steel cage, it offers a robust solution for applications requiring ABEC1 precision and dependable operation at speeds up to 32,000 rpm.
635zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 635 | Basic Bearing Number | Denotes the standard bearing dimensions: 5mm bore, 19mm OD, 6mm width. |
| zz | Shielded on Both Sides | Indicates the bearing is fitted with non-contact metal shields (300 Series Stainless Steel) on both sides. This protects the internal components from dust and debris while minimizing friction, contributing to its high-speed capability. |
635zz Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Radial Load Capacity: The deep, continuous raceways on both rings are optimized to support significant radial loads (dynamic: 447 lbf / static: 161 lbf), making it a versatile choice for various mechanical systems.
- Shielded for Contamination Resistance: The dual zz shields act as a physical barrier, preventing the ingress of solid contaminants. This feature enhances bearing life and reliability in less-than-ideal environments, supporting the MC3 radial internal clearance specification.
- High-Speed Stainless Steel Cage: The stainless steel cage effectively guides and spaces the six precision balls, ensuring stable operation and low vibration at the bearing's limiting speed of 32,000 rpm.
- Precision and Consistency: Built to ABEC1 tolerance class, this bearing provides predictable performance and smooth running, which is essential for consistent operation in automated equipment and precision instruments.
635zz Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Precision Spindles in Dental and Medical Handpieces
- Office Automation Equipment (Printers, Scanners, Copiers)
