Product Name: China Manufacturer of Sg Single Screw Plastic Extruder Gearbox Model NO.: SG Series Type: Bevel Gear Be Used in: PVC Extruder Gears Be Mount Type: Vertical and Horizonal Manufacturing Method: Rolling Gear Trademark: SG Transport Package: Wooden Case Specification: SGS authentication Origin: Hangzhou of China HS Code: 8483409000 Product Description Product specificationZLYJ series speed reducers are high precision hardening tooth flank transmission part with thrust bearing housing. They are designed for plastic screw-rod extruder according to JB/T9050.1-1999. The gears and axes are made of high strength alloy steel. The gears are manufactured by way of carburizing hardening, precision grinding. Its precision is up to Grade 6(JB/T9050.1-1999.). Hardness of tooth flank is HRC54-62. Thrust bearing is in front of output hollow shaft to accommodate screw-rod back pressure forces. Bearings, oil seals and some other standard units are quality products and they can also be imported goods to meet customers' requirements. This kind of speed reducer has the characteristic of small volume, high load capacity, stable transmission, low noise, high efficiency. They properties reach levels of foreign products of the same kind and it can take place of them.Main features1. Input shaft rotation speed is not more than 1500r/min.2. Its ambient temperature range is within 0 to 35 centigrade. If it is lower than 0 centigrade, pre-heating of the lubricant will be necessary before start-up, while cooling is suggested in case of a temperature higher than 35 centigrade.ParametersProduct show
