636zz Bearing Product Overview & Core Advantages
The 636zz is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. As a metric series bearing, it features a compact design with a 6mm bore, 22mm outside diameter, and 7mm width, making it ideal for applications with space constraints. Its shielded (ZZ) construction provides effective protection against contamination while retaining lubrication, contributing to its long service life. Engineered to primarily handle radial loads, this bearing is characterized by its low friction and smooth operation, supported by a precision ABEC1 tolerance class. Manufactured from high-grade chrome steel with a stainless steel cage, it offers excellent durability and consistent performance.
636zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 636 | The basic bearing designation, indicating the bearing size and series (6mm bore, 22mm OD, 7mm width). |
| zz | Denotes that the bearing is equipped with non-contact metal shields (ZZ) on both sides. This provides protection from large particulate contaminants while allowing for higher limiting speeds compared to contact seals. |
636zz Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High Load Capacity: The deep, continuous raceways on both rings are optimized for handling radial loads efficiently. With a dynamic load rating of 637 lbf and a static load rating of 256 lbf, it provides reliable support in demanding applications.
- Shielded for Contamination Protection: The 300 series stainless steel shields (ZZ) protect the internal components from dust and debris, extending bearing life and reducing maintenance needs. This design is suitable for applications where sealing is required without the added friction of contact seals.
- Precision & Smooth Operation: Manufactured to ABEC1 precision class tolerances, this bearing ensures consistent running accuracy and low vibration. The complement of 7 high-precision chrome steel balls and a robust stainless steel cage ensures stable operation and even load distribution.
- Versatile Operating Range: The bearing is suitable for a temperature range from -30°C to 110°C and features a standard MC3 radial internal clearance (0.002mm to 0.013mm), making it adaptable to various operational environments and preload conditions.
636zz Bearing Typical Application Areas
- Electric Motors: Widely used in small to medium-sized motors for fans, pumps, and appliances due to their high-speed capability (up to 30,000 rpm) and reliable radial load support.
- Power Tools: Ideal for drills, grinders, and sanders where compact size, durability, and protection from debris are critical.
- Office Machinery & Computer Peripherals: Employed in printers, scanners, and cooling fans for smooth and quiet operation.
- Material Handling Equipment: Suitable for conveyor rollers and small gearboxes that require robust ball bearings with built-in contamination shields.
- General Industrial Machinery: A versatile component in various machinery requiring a cost-effective, precision single row bearing for radial support.
