The MTWB 6202 Low Noise EMQ Bearing is a precision-engineered deep groove ball bearing designed for applications demanding exceptional rotational accuracy, minimal vibration, and whisper-quiet operation. As part of MTWB technical breakthrough in miniature and small deep groove ball bearing (DGBB) manufacturing, this bearing leverages advanced production technology, precision grinding, and stringent quality control to deliver outstanding performance in high-speed, low-noise environments.
With standard dimensions of 15 mm bore diameter, 35 mm outer diameter, and 11 mm width, the 6202 EMQ bearing is fully interchangeable with ISO-standard 6202 bearings, making it a drop-in replacement for countless applications worldwide.
1. Electric Motor Quality (EMQ) Certification
The 6202 Low Noise EMQ Bearing is engineered specifically for electric motor applications requiring reduced noise and vibration levels. By implementing targeted quality control during the grinding process of the inner ring raceway, MTWB significantly reduces bearing noise. Our high-precision machines and top-notch techniques refine every aspect of the bearing – from the raceways to the balls – ensuring they exceed industry standards.
2. Rigorous Noise & Vibration Testing
MTWB conducts 100% inspection on every bearing before it leaves the factory. Noise detection is available across Z1, Z2, Z3, and Z4 levels, while vibration detection is classified as V1, V2, V3, and V4. Customers can select different levels based on specific application requirements. Through these rigorous testing and evaluation procedures, we guarantee that every batch meets the criteria for low noise and high efficiency.
3. Premium Material Selection
We choose only the finest materials, including G95Cr18 and GCr15 bearing steels, plus corrosion-resistant 300-series stainless steel. These top-grade materials ensure your bearings are strong, durable, and whisper-quiet, ready to perform flawlessly for the long haul.
4. Superior Surface Finishing
Raceways are super-finished to produce mirror-like surfaces, while high-quality balls with near-perfect sphericity are used to minimize high-frequency noise and vibration. Geometrical tolerances control features such as roundness, concentricity, runout, and parallelism.
5. Optimal Lubrication
MTWB bearings are typically lubricated with antirust oil for open bearings or lithium-based grease for sealed bearings. Custom grease specifications are available according to customer requirements. Sealed versions are pre-lubricated for life and require no maintenance.
6. Customization Options
MTWB offers design optimization services, including special raceway curvature design to improve lubrication efficiency. Custom internal clearances (CN, C3, C4), sealing configurations (open, ZZ metal shields, 2RS rubber seals), and precision grades are available to meet specific application needs.
