Othmro Bearing 17Mmx30Mmx7Mm Plastic 6903 2RS Review

【Size】-Bore(Inner Dia):17mm/0.66";Outer Diametre:30mm/1.17";Width(Thickness):7mm/0.27";Model:6903-2RS;Dynamic load Cr(kN):4.6;Static load Cor(kN):2.6;Material:Carbon Steel;Accuracy class:P0;Sealed dustproof form:Double plasatic sealed. 【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
