MTWB has achieved significant technical breakthroughs in miniature and small deep groove ball bearing (DGBB) manufacturing, providing precision bearing solutions for high-speed, low-noise and space-constrained applications. Leveraging advanced production technology, precision grinding, and strict quality control, MTWB miniature DGBB bearings deliver outstanding rotational accuracy, long service life and reliable performance for medical devices, robotics, precision motors, instruments and industrial automation equipment.
With the ever-increasing demand for precision bearings, MTWB continuously seeks for technical improvement and up till now can provide you with a full range of ball bearings from 0.6mm ID to 380mm OD. Yes, as small as 0.6mm ID, at P4 precision class! It is by far the smallest precision ball bearing that you can find on earth. Our success for making this world’s smallest ball bearing is originally driven by medical application, yet we believe this technology can also be extended to other industrial application.
Bearings are the key components of electric motors. The key to low noise bearing lies in reducing vibration. By implementing targeted quality control during the grinding process of the inner ring raceway plays an important role in reducing the noise of EQM bearing. 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.
We don't just say MTWB bearings are “quiet”, we guarantee it. First, we conduct 100% inspection on the sealing effect of every bearing before it leaves the factory, in order to reduce the possibility of dust and other debris entering the interior of the bearing ring due to inadequate sealing, which may lead to reduced bearing efficiency over long-term use.
Furthermore, we are also aware that grease has become a major factor influencing bearing noise. MTWB bearings are usually lubed antirust oil for open bearing or lithium-based grease for closed bearing. Also, the specified grease can be used according to the customer’s requirement.
In order to accurately assess the noise level of bearings, we need to strictly follow the testing specifications and make full use of noise testers and vibration testers for inspection. The noise detection of bearings is divided into Z1, Z2, Z3, and Z4 levels, while the vibration detection levels are classified as V1, V2, V3, and V4. Among them, motor bearings have stricter requirements for bearing vibrations. Customers can choose different levels based on specific requirements. Through these rigorous testing and evaluation procedures, we guarantee that every batch of bearings meets the criteria for low noise and high efficiency.
Materials matter! That's why we choose only the finest, like 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 long haul.
Bosch’s 6001 bearing features optimized internal dimension (special raceway curvature design), improving lubrication efficiency by 30% and controlling rotational accuracy within ±0.5μm.
Quote from Bosch Engineer: “The optimized lubrication efficiency of the new 6001bearings reduced our CVT system’s energy consumption by 8%.”
ZF’s steering system adopts a triple-lip seal structure combined with a special grease (high-temperature
silent grease) that gives a reduction of noise by 15dB.
