S6905zz Bearing Product Overview & Core Advantages
The S6905zz is a single row deep groove ball bearing designed for high-performance applications requiring reliability and precision. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently while maintaining a compact design with a 9 mm width. The inclusion of shielded seals (ZZ) protects against contamination, making it a robust and durable choice for various industrial settings.
S6905zz Bearing Model Code Explained, Specifications & Naming Convention
| S | Denotes the ring and ball material as Stainless Steel, providing enhanced corrosion resistance. |
| 6905 | The bearing series and size designation, indicating a 25 mm bore, 42 mm outside diameter, and a 9 mm width. |
| ZZ | Signifies that the bearing is equipped with non-contact shields on both sides. This provides effective protection against dust and debris while minimizing friction. |
S6905zz Bearing Structural Features & Performance Benefits
Deep Groove Geometry & Single Row Design: The deep raceway and single row of balls are optimized for high radial load capacity, as evidenced by its 1418 lbf dynamic and 921 lbf static ratings. This design ensures stable operation under load.
Shielded Protection (ZZ): The non-contact steel shields retain lubricant and exclude large contaminants, enhancing bearing life and reliability in challenging environments. This contributes to a limiting speed of 14,400 rpm.
Stainless Steel Construction: All critical components—rings, balls, and cage—are made from stainless steel. This provides superior resistance to rust and corrosion, making it suitable for applications exposed to moisture or chemicals within its temperature range of -86 to 230 °F.
Precision & Clearance: Manufactured to ABEC-1 tolerance class with a C0 radial internal clearance (0.006mm to 0.020mm), this bearing delivers consistent and smooth running performance, suitable for a wide array of general precision applications.
S6905zz Bearing Typical Application Areas
The S6905zz is ideally suited for applications demanding corrosion resistance, moderate speeds, and reliable performance. Common uses include:
- Food Processing & Packaging Equipment (where washdowns are common)
- Medical Devices and Instrumentation
- Electric Motors and Small Gearboxes
- Agricultural Machinery (for components exposed to the elements)
- Marine and Chemical Handling Equipment
