Product Description

Product Description

Deep Groove Ball Bearing S623ZZ 624 S625ZZ  Stainless Steel Bearing for Machinery

  Specifically engineered for demanding environments, the S620 series—ranging from the compact S623 to the versatile S629—delivers exceptional performance, uncompromising durability, and absolute precision. Whether you are designing advanced medical devices, upgrading food processing machinery, or manufacturing high-speed micro motors, our stainless steel bearings provide the perfectly reliable solution.
Manufactured from high-grade stainless steel (available in AISI 440C, 304, or 316 upon request), these bearings are inherently corrosion-resistant and waterproof. Unlike standard chrome steel bearings, our S620 series thrives in environments exposed to moisture, mild acids, and frequent washdowns.

Product Features

• Material: They are made of high-quality stainless steel (such as AISI 440C or 316). This makes them highly resistant to rust, water, and harsh chemicals.
• Weight: They have an excellent strength-to-weight ratio. Even though they are relatively light, they can carry heavy loads. This helps reduce the total weight of the machine.
• Dimensions: They are available in a very wide range of sizes. From tiny micro-bearings for small electronics to larger ones for heavy machines, their standard sizes make them easy to fit into compact designs.
• Precision: There are many accuracy ranges. Every accuracy cevel keeps running very smoothly, makes little noise, and can spin at high speeds with low friction.
• Sealing: They usually come with strong metal shields (ZZ) or rubber seals (2RS). These seals keep dust and water out while keeping the lubricating grease inside, making them almost maintenance-free.
• Application Fields: Because they are waterproof and rustproof, and do not rust easily, they are perfect for strict environments. They are widely used in food processing machinery, medical equipment, chemical pumps, and marine (ocean) tools.

This ensures rigorous defect control, continuous improvement, and world-class reliability for every bearing you receive.

Q2: Do you accept OEM/ODM? Can you produce non-standard bearings?
A: Absolutely. Non-standard customization is one of our core strengths. Just send us your technical drawings, dimensions, or physical samples. Furthermore, we fully support brand customization, including laser marking on bearings and designing custom color boxes to help build your brand identity.
 
Q3: How do you guarantee the bearing quality? Do you accept 3rd-party inspections?
A: We stand behind our quality with a solid 12-Month Warranty from the date of arrival. Any manufacturing defects will be replaced for free. For your complete peace of mind, we 100% welcome Third-Party Inspections (such as SGS, Intertek, or BV) before shipment.
