Deep groove ball bearings are the most widely produced and utilized bearing type globally due to their simple, versatile, and easy-to-use design. The 608 Series (also known as Z809) is an industry-standard miniature bearing designed primarily to accommodate radial loads, while also capable of supporting moderate axial loads in both directions. When manufactured with increased radial clearance, it can function similarly to an angular contact bearing, handling even larger axial loads.
Note: The designation "Z809" is commonly used in the market when the standard "608Z" stamping is read upside down; functionally, they are the exact same high-precision bearing.
We provide highly customizable configurations to match your precise engineering and price-point requirements.
Item | Specification |
Bearing Series | 608 / Z809 |
Dimensions (ID × OD × W) | 8 mm × 22 mm × 7 mm |
Weight | ≈ 0.015 kg |
Precision Grades | P0 (ABEC-1) to P2 (ABEC-9) |
Quality Standard | ISO9001:2000 |
Bearing Material Options | Chrome Steel, Stainless Steel, Carbon Steel, Ceramic |
Extensive sealing and snap ring configurations:
Open: No seals or shields for oil-lubricated environments.
Shielded (Z, ZZ / 2Z): One or two-sided metal shields for dust protection and high speed.
Sealed (RS, 2RS, RZ, 2RZ): One or two-sided rubber/non-contact seals for superior moisture and dirt resistance.
Snap Ring (N, NR): Available with a snap ring groove on the outer ring (N) or with an external snap ring (NR) for easy axial location in housings.
The 608/Z809 bearing is engineered to deliver reliable performance in demanding, high-volume production environments:
High accuracy: Strict ABEC tolerance controls ensure stable, high-speed rotation without vibration.
Low noise: Precision-ground raceways and high-quality balls result in ultra-quiet operation, crucial for consumer electronics and office equipment.
Low weight: At just 0.015 kg, it is perfect for weight-sensitive miniature mechanisms.
Full customization: We provide standard and non-standard miniature sizes tailored exactly to your operational needs.
Because of its compact size (8x22x7 mm) and robust performance, this bearing is ubiquitous across countless industries, including:
Electric machines, small motors, and power tools.
Automotive components and tractor sub-assemblies.
Water pumps, agricultural machinery, and textile equipment.
Skateboards, inline skates, and hobbyist RC vehicles.
We are a dedicated B2B manufacturing partner. We offer:
OEM & Design Services: We can supply neutral brands, imported brands, or fully customized buyer labels etched directly onto the bearing shields.
Packaging: Industrial tube/tray packaging for assembly lines, or customized individual boxes according to buyers’ requirements.
Flexible Payment: 100% T/T, 30% T/T advance + 70% against B/L, L/C at sight, Western Union, and PayPal.
Q1: What is the difference between a 608Z bearing and a Z809 bearing?
A: There is no physical difference. "Z809" is simply the result of reading the standard "608Z" factory stamping upside down. Both refer to the exact same 8x22x7 mm bearing.
Q2: What ABEC rating should I choose?
A: ABEC-1 (P0) is suitable for most general industrial applications. If your application requires very high speeds, ultra-low noise, or high precision (like specific electric motors or precision instruments), we recommend ABEC-5 (P5) or higher.
Q3: Which material is best for my application?
A: Chrome steel is the standard for high load and long life. Stainless steel is required for corrosive or wash-down environments. Carbon steel is a budget-friendly option for low-speed/low-load uses, while Ceramic is used for extreme high-speed or high-temperature specialty applications.
Q4: Can you customize the brand and packaging?
A: Yes, we offer full Buyer Label and OEM services. We can mark your specific brand name on the bearing and provide packaging that meets your exact retail or industrial specifications.
