Обыкновенные стальной ролик

Ordinary steel roller Product introduction NC roller is introduced with the world's advanced level of Japanese conveyor corporation (NC) technology and complete set of manufacturing process, according to MT821-2006 (most) of conveyor roller. It has small, rotating radial micrometers low resistance and long service life etc. Widely used in mining, metallurgy, electric power, ports, building material industry, etc. Product performance 1 radial beat small Roller adopts national fixed-point enterprise producing steel tube, the roller bearing steel plate, adopt high quality professional machining, stamping bearing assembly adopts the best tolerance, guarantee the radial beat quantity is far below the national standard. 2 rotating small resistance Choose the C3 group small clearance, deep groove ball bearings, ensuring the smooth running, low noise, long service life, roller labyrinth seal filled with middle tianjin fat general lithium grease 2, ensure roller has more small resistance, with effective energy saving effect. 3 dustproof waterproof performance excellence Sealing roller for lacunar type, sealing raod, DT75 80mm reaches longer DTII type, type of 15-20mm, seal clearance to 0.5 mm. Won three patents, sealing material chooses PBT - G, compression ability is strong, can reach 29000N above, low temperature, high temperature deformation, dustproof, waterproof performance excellence. 4 permanent lubrication NC roller adopts double sealed the deep groove ball bearings, filling in manufacturing process quality lithium base greases permanently sealed, 2, without adding grease. And long service life As a result of the best quality with tolerance and fitting, roller of various performance effectively improve, thus greatly extend the service life of the roller. NC roller life guarantees in 50,000 hours. Using occasions NC belt conveyor roller as the parts and accessories, suitable for all the belt conveyor, widely used in coal mine, dock, metallurgy, electric power, ports, coking, water conservancy, building material industry, etc. Because of its good performance, it is in the dust, drench water environment. Because of the metal corrosion resistance is weak, the reason is not suitable for use in strong acid, strong alkali, Marine climate environment. In the bad environment should be used according to the circumstance such as ceramic roller selection, nonmetal roller, wear-resisting cast Tito roller, wear-resisting resin roller, highspeed aluminum roller etc for specific work environment.
