As the situations from Covid-19 return regular in China, IT-ROLL also restore manufacture. And invested in a BVT-6S bearing vibration measuring instrument. The scope of it includes deep ball bearing, single/double row angular contact bearing, cylindrical roller bearing, single/double row tapered roller bearing, and has both BVT and S0910 (speed type and acceleration type) 2 modes. The maximum measure outer diameter is 200mm. Thisi measuring instrument provide reliable data for sampling and defect analysis and reduce dispersion of product quality, improve the overall product reliability. Inspection center of IT-ROLL BVT-6S the new instrument is used to measure bearing vibration. From left is BVT-6S, BVT-A, S 0910-III. The inspection ranges from the inner diameter of 3mm to the outer diameter of 200mm. Size inspection instrument for inner and outer rings. Metallographic analysis instrument to ensure that each batch of bearings are made of qualified steel. Roughness and contour instrument...

When we choose the bearings, always care about these points 1.type, rating load and limit speed; 2.precision; 3.size; 4.sealed or not; 5.type of lubricating grease . The same type of bearing, can we use no matter which factory made it? In fact, each bearing manufacturer has the same specification of bearing except for the type, precision, sealed or not, all of which are different. For example, 7306B, there are 9 steel balls product, 11 balls(IT-ROLL's conventional product),12 balls(IT-ROLL custom product). When you choose, you can't rely solely on experience, and no matter what the factory and design is, to draw a concusion. A common sense, the bigger steel ball, the higher rating load. As knows, the rating load is proportional to the quantity of steel balls, and to the square of the diameter of the steel balls. Usually, the quantity of steel balls is less, the diameter of steel balls is larger. All right, the larger the balls, the thinner inner and outer ring in the same size bearing. At that...

Oct.8,2018, Mr.NI YAOMING, (Warden of Shanghai Minhang District) , bring the government team visited Shanghai IT-ROLL bearing, to show the support of government under the background of SINO-USA trade friction.
