S636zz Bearing Product Overview & Core Advantages
The S636zz is a precision miniature ball bearing designed for demanding applications requiring high reliability and consistent performance. As a single row deep groove ball bearing, it is primarily engineered to support radial loads, but can also accommodate moderate axial loads in both directions. Its compact bearing dimensions (6mm bore, 22mm OD, 7mm width) make it ideal for space-constrained assemblies. Manufactured entirely from stainless steel, including the balls and cage, it offers excellent corrosion resistance. With shielded construction and pre-defined radial internal clearance, this bearing delivers robust performance and extended service life in a wide range of industrial and precision equipment.
S636zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| S | Stainless Steel | Provides superior corrosion resistance. |
| 6 | Deep Groove Series | Optimized geometry for handling radial and some axial loads. |
| 36 | Bore Diameter Code (6mm) | Specifies the precise inner diameter for shaft fitting. |
| zz | Shielded on Both Sides | Offers effective protection against contaminants while retaining lubricant. |
S636zz Bearing Structural Features & Performance Benefits
Optimized Deep Groove Raceway: The geometry of the raceways is designed for smooth operation and efficient load distribution, contributing to low noise and vibration levels.
Full Complement Stainless Steel Construction: The use of stainless steel for the inner ring, outer ring, balls, and cage ensures dimensional stability and resistance to rust, making it suitable for harsh environments and cleanroom applications.
Shielded Protection: The non-contact stainless steel shields (zz) help to retain lubrication and exclude larger particulate contaminants, enhancing bearing longevity without significantly increasing rotational torque.
Precision Tolerances: Manufactured to ABEC1 tolerance class, this bearing provides reliable and repeatable performance for a wide range of general precision applications.
Controlled Internal Clearance: The MC3 radial internal clearance group (0.002mm to 0.013mm) is suited for applications where operational temperatures and fits must be carefully managed to prevent preload or excessive play.
S636zz Bearing Typical Application Areas
The S636zz is a versatile component found in numerous precision and industrial devices, including:
- Small Electric Motors: Used in fans, pumps, and power tools.
- Precision Instruments: Ideal for optical encoders, medical devices, and laboratory equipment.
- Office Automation Equipment: Commonly used in printers, scanners, and copiers.
- Food Processing and Packaging Machinery: Its stainless steel construction meets hygiene requirements.
- Robotics and RC Models: Provides reliable motion control in joints and drive systems.
