S624 Bearing Product Overview & Core Advantages
The S624 is a metric single row deep groove ball bearing engineered for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to primarily handle radial loads and is characterized by its compact dimensions (4mm bore, 13mm OD, 5mm width), making it ideal for space-constrained assemblies. Its ABEC1 tolerance class and optimized internal geometry ensure smooth, quiet operation, while its high limiting speed of 36,000 rpm makes it suitable for demanding, high-speed scenarios.
S624 Bearing Model Code Explained, Specifications & Naming Convention
- S: Denotes the bearing ring and ball material as Stainless Steel.
- 6: Indicates the bearing series, relating to its dimensions and load capacity.
- 24: Specifies the bore diameter code. For this metric bearing, it corresponds to a 4 mm bore diameter.
The absence of additional suffixes indicates an open (unsealed) design with a standard cage, requiring external lubrication.
S624 Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and suitability for harsh environments or washdown applications.
- Deep Groove Raceway: The uninterrupted deep groove geometry enables the bearing to handle not only radial loads but also moderate axial loads in both directions.
- High-Speed Capability: The combination of a precision-ground raceway, seven 2.381 mm balls, and a stainless steel cage contributes to low friction and a high limiting speed, supporting smooth operation at up to 36,000 rpm.
- Precision Performance: Manufactured to ABEC1 tolerance standards with an MC3 radial internal clearance (0.002mm to 0.013mm), this bearing ensures consistent running accuracy and low vibration.
S624 Bearing Typical Application Areas
- Small precision electric motors and spindles
- Medical and dental handpieces
- Optical encoders and instrumentation
- Radio control models (drones, cars)
- Office automation equipment and small fans
- Food processing machinery (where corrosion resistance is critical)
