Othmro Bearings 4X12X4Mm Galvanized Shielded Review

【Size】-Bore(Inner Dia):4mm/0.16";Outer Diametre:12mm/0.47";Width(Thickness):4mm/0.16";Model:604ZZ;Dynamic load Cr(kN):0.97;Static load Cor(kN):0.36;Material:High Carbon Steel;Vibration/noise level:Z1;Accuracy class:P0;Sealed dustproof form:Double galvanized iron cover Shielded. 【High Quality】-The bearings is made of bearing steel for durability and resistance to rust, corrosion and deformity under heavy loads. 【Feature】-Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads,and it has small friction and high-limit speed. 【Strictly Shielded】-The bearing has shield to keep lubricant in and contaminants out;protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. 【Application】-Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment,robotics,dental equipment, elevators, rolling mills, ship rudder shafts, aggregate crushers,skateboards, inline skates, and scooters, among others
