Deep groove ball bearings are the most widely used bearing class globally due to their simple, effective, and non-separable design. The 626 Miniature Ball Bearing is engineered to accommodate proportional radial loads and moderate thrust (axial) loads in both directions. When manufactured with increased radial clearance, these bearings can mimic the function of angular contact bearings to handle even larger axial forces, making them incredibly adaptable for compact machinery.
Ensure exact fitment for your assembly lines or repair kits using the dimensions below.
Item | Specification |
Bearing Series | 626 |
Dimensions (ID × OD × W) | 6 mm × 19 mm × 6 mm |
Weight | ≈ 0.008 kg |
Precision Grades | P0 (Standard), P6, P5, P4 |
Cage Material | Metal (Steel) or Rubber/Polymer |
Load Profile | Radial and Axial (Thrust) loads |
Quality Standard | ISO9001:2000 |
Available sealing configurations:
Open (626): No shields or seals, ideal for clean, continuously lubricated environments.
Shielded (626Z / 626ZZ): Features one (Z) or two (ZZ) non-contact metal shields. Provides protection against larger debris while retaining grease and allowing for extremely high rotational speeds (up to 35,000 RPM in some configurations).
Sealed (626RS / 626-2RS): Features one (RS) or two (2RS) contact rubber seals. Offers the highest level of protection against dust, dirt, and moisture, making them splash-proof and ideal for exposed applications.
The 626 series delivers exceptional value for OEM manufacturers and aftermarket distributors:
Versatile load handling: Can smoothly bear both radial and axial loads simultaneously.
High-speed performance: Precision manufacturing (up to P4 grade) minimizes friction, vibration, and noise during rapid rotation.
Well-produced & durable: Factory pre-lubricated with high-quality grease, ensuring a long, maintenance-free service life.
Pairing capability: Can be utilized in paired arrangements to increase rigidity and load capacity in compact shaft designs.
Due to its 6 mm bore size, the 626 bearing is a fundamental component in small-scale mechanics. Common applications include:
Small electric motors and machine tools.
Water pumps and agricultural machinery.
Auto and tractor sub-assemblies.
Medical technology, 3D printers, and textile machinery.
We provide a flexible and reliable supply chain for global distributors. We offer comprehensive OEM & ODM services, allowing you to choose between Chinese brands, imported brands, or having your own custom brand laser-marked on the bearings. Packaging can be configured to your exact requirements, from industrial bulk tubes to customized retail boxes.
Trade & Payment Terms:
Delivery: Fast turnaround, normally 3–15 days for ready/in-stock goods.
Payment Options: 100% T/T, 30% T/T advance + 70% against B/L copy, 30% T/T advance + 70% against L/C at sight, PayPal, or Western Union.
Q1: Can I remove the seals or shields if my application requires an open bearing?
A: Yes. If you purchase a 626-2RS or 626ZZ and realize you need an open bearing, you can carefully remove the rubber seals or metal shields with a small tool. However, it is more cost-effective to order the exact configuration you need.
Q2: Are these bearings pre-lubricated?
A: Yes, the shielded (ZZ) and sealed (2RS) variants are pre-lubricated at the factory with high-grade grease and are sealed for life, requiring no maintenance.
Q3: What does the "P6" or "P5" precision rating mean?
A: P0 is the standard normal precision class (equivalent to ABEC-1). P6 and P5 denote progressively higher precision classes with tighter dimensional tolerances, essential for ultra-high-speed or highly sensitive applications.
Q4: Can you provide customized packaging for our retail stores?
A: Absolutely. We offer "Package according to buyers’ requirement," meaning we can produce single-color boxes with your barcodes and branding for easy retail distribution.
