Advantage
Feature: NC distance adjustment/hydraulic emergency brake/automatic temperature control
1. The roller is made of chilled casting vanadium & titanium alloy iron which is hard and wear-resisting, the surface hardness is above 70degree, the surface coating is about 15mm.
2.Hard tooth gear reducer with well-design structure, low noise, high efficiency and long service life.
3.Self-aligning bearing is well matching with the bearing inside leakage-proof device. The sealers are made of high temperature,wear, oil resistance material,which have very good sealing effect.
4.All main electrics are imported, the alternating current contactor is Shilin brand. The switch and button are Taiwan Tend brand.
5.Circulating lubrication system solves the oil leakage problem. The feature of this system is easy to maintain,easy to replace.
6.This machine is installed with overload protection device which protect the machine will not broken if the machine is overload.
The machine will reverse 1/3 round when press the emergency stop button,which sure the production safety.
7.The “U” shape frame is whole set casting, but other factory welded together.
8.The machine base is welded by national standard I steel.
