Key Specifications & Benefits of Premium Deep Groove Ball Bearings
| Description | Core Value |
|---|---|
| Models: 6201, 6202, 6204, 6206, 6210, 6301–6308, 6401–6402 | Wide cross-reference compatibility with SKF, NSK, NTN, Koyo — seamless OEM replacement |
| Seals: ZZ (metal shields) / 2RS (rubber contact seals) | Enhanced dust/moisture resistance + pre-lubricated for extended maintenance-free operation |
| Material: High-carbon chromium bearing steel (GCR15) | Superior hardness (HRC 60–64), fatigue resistance & dimensional stability |
| Precision Grades: P0, P6, P5, P4 | Tight tolerances ensure smooth rotation, low noise, and high-speed reliability |
| Vibration Levels: Z1V1 to Z3V3 | Optimized for quiet performance in precision equipment (e.g., pumps, motors, conveyors) |
| Load Type: Radial + moderate axial loads | Robust deep-groove design delivers balanced load capacity and rigidity |
| Standard Size Range: e.g., 20×47×14 mm (6201) | Compact yet durable — ideal for space-constrained industrial & automation applications |
| Origin & QC: Manufactured in ISO 9001-certified Chinese facilities | Rigorous 100% dimensional & rotational testing; traceable batch documentation |
| OEM/ODM Support & Custom Packaging | Private labeling, branded cartons, palletized export-ready shipment |
| Applications: Electric motors, gearboxes, agricultural machinery, HVAC fans, food processing lines | Proven reliability across demanding environments — from dusty farms to clean-room systems |
Why choose ours over generic alternatives? We match SKF’s fit/function while offering faster lead times, full model coverage, and technical support — including interchange charts and mounting guidance. All bearings meet or exceed ISO 15, DIN 625, and ABEC standards.
