S628zz Bearing Product Overview & Core Advantages
The 628zz is a single row deep groove ball bearing designed for reliable performance in various industrial applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions, making it a versatile and compact solution. The inclusion of shielded seals on both sides helps retain lubrication and protect against contamination, contributing to its durability and suitability for applications requiring ABEC1 precision.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 628 | Basic bearing designation indicating the bearing size (8mm bore, 24mm OD, 8mm width). |
| zz | Denotes shielded seals on both sides of the bearing. This helps protect the internal components from contaminants. |
S628zz Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Versatile Load Capacity: The deep, continuous raceways enable the bearing to support high radial dynamic load ratings (574 lbf) and accommodate axial loads from either direction, making it highly versatile.
- Stainless Steel Construction: All critical components are made from stainless steel, providing superior corrosion resistance and making it ideal for applications exposed to moisture or harsh environments.
- Shielded Protection: The non-contact shielded seals help retain the factory-applied lubricant and exclude larger particulate contaminants, extending service life and reducing maintenance needs.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 / 0.002mm to 0.013mm), ensuring smooth and consistent operation.
S628zz Bearing Typical Application Areas
This bearing is commonly found in:
- Electric Motors and Small Gearboxes
- Medical and Dental Equipment
- Food Processing Machinery
- Precision Instruments and Optical Devices
- Conveyor Systems and Idler Pulleys
- Office Automation Equipment (Printers, Scanners)
