1. Product Introduction

The 6202-ZZ is a single-row deep groove ball bearing fitted with double-sided metal shields, purpose-built for medium and high-speed, low-noise and dust-proof running conditions. It is manufactured from high-purity GCr15 bearing steel and hardened through precise quenching and tempering, giving it high hardness, strong wear resistance and stable fatigue resistance. The finely polished raceways and steel balls deliver smooth, low-friction rotation, while the ZZ metal shields keep dust, particles and debris out and hold the factory grease in place. Compact in structure and reliable in performance, the 6202-ZZ (15x35x11mm) is a core matching component for small motor-driven equipment and household air-treatment appliances.

2. Product Features

• Dust-proof metal shielding: Double-sided ZZ metal shields isolate external dust and impurities and lock the lubricating grease firmly, preventing grease drying and leakage and greatly extending service life.
• Low-noise and smooth rotation: Precision grinding of raceways and steel balls reduces running friction and vibration for quiet, stable operation that suits noise-sensitive home appliances.
• High-speed capability: The non-contact metal shield design keeps friction and heat low, supporting continuous high-speed running with low power loss.
• Combined radial and axial load: The deep raceway geometry lets the bearing carry radial load together with moderate bidirectional axial load under uniform stress.
• Standard interchangeable size: The 15x35x11mm envelope matches the international 6202 series for simple drop-in assembly and low maintenance cost.

3. Product Advantages

All 6202-ZZ bearings are strictly inspected against international industry standards. Precision processing and full inspection give the products stable quality, high consistency and strong interchangeability. Factory-direct supply supports customized precision and packaging, with sufficient stock and fast delivery, providing a reliable bearing solution for global customers.

5. Application Scenarios

The 6202-ZZ shielded deep groove ball bearing is widely used in medium and high-speed small motor drives, and is especially suitable for air purifiers and humidifiers, where quiet, clean and dust-resistant running is essential. Its stable dust-proof and low-noise performance also adapts well to other compact household air-treatment appliances, small cooling fans and light mechanical transmission devices, ensuring steady, clean and long-term operation of the matching equipment.
