SS 608 ZZ/2RS stainless steel deep groove ball bearings

The SS 608 ZZ/2RS stainless steel deep groove ball bearing is not only our best-selling product but also a universal standard in global industrial and consumer markets. From precision motors to high-end skateboards, the SS 608 is everywhere. We have redefined this classic bearing by perfectly combining industrial-grade stainless steel corrosion resistance with competition-grade high-speed performance. Whether you need extremely low friction for free rotation or long-lasting durability in humid environments, our SS 608 provides a superior experience compared to ordinary carbon steel bearings.

  • The applications of SS 608 are extremely diverse, and we focus on the following high-demand markets:

    Sports equipment: Skateboards, inline skates, fidget spinners (emphasizing spin time and rust resistance).

    3D printers and CNC machines: Lead screws, extruder idler pulleys (emphasizing precision and wear resistance).

    Micro motors and cooling fans: Vacuum cleaner motors, computer fans.

    Food conveyor rollers: Conveyor belt components that require frequent washing.

    Smart home devices: Automatic curtain motors, robotic vacuum cleaners.

  • Racing-Grade Smoothness: Thanks to G10 grade high-precision steel balls and finely ground P6 grade raceways, our SS 608 bearings have an extremely low friction coefficient. This makes them ideal for high-speed motor and pulley applications, resulting in higher speeds, less heat generation, and quieter operation.

    More Than Just Rust Protection:
    AISI 420: Deep-cryogenically treated, combining high hardness and rust resistance, making it the preferred choice for wear resistance in 3D printers and high-speed motors.
    AISI 316/304: Provides almost permanent corrosion protection for food machinery or outdoor humid environments.

    Flexible Sealing Structures:
    Non-contact ZZ/2RZ: Designed for ultimate speed, with no friction resistance, suitable for cooling fans and skateboards.
    Contact 2RS: Provides tight dust and water protection, locking in grease, suitable for dusty industrial environments.

    Wide Lubrication Compatibility: In addition to standard quiet grease, we also offer high-temperature grease and food-grade grease (for food processing lines) to meet your specific needs.

  • "In-stock and ready to ship, with consistent batch quality." As our best-selling model, we maintain a large safety stock of the SS 608 to ensure fast delivery, even during peak seasons. Understanding that the SS 608 is frequently used in automated assembly lines, we have specifically introduced fully automated assembly and noise testing equipment to ensure highly consistent tolerance distribution (C0/C3 clearance) across every batch, eliminating variations in quality and ensuring smooth operation of your automated assembly lines.
