Zax100 Zx200 Zx240 Zax230 Zax250 Excavator Track CARRIER ROLLER 4332040 4360509 4614911 for Hitachi
HIGH QUALITY,HIGH ACCURACY,LONG SERVINCE LIFE.
Roller Body:Adopting the good hardenability 40 Mn2 steel through forging. The heat treatment of tempering and medium-frequency induction surface hardening assure it’s strength and wear resistance. The surface HRC IS 52-60, depth of hardening is 8-20mm.
Axle:Adopting 45# steel,tempering and medium-frequency induction surface hardening.
The surface HRC is 52-60,depth of hardening is 3-6mm,comprehensive is good.
Floating seal:Adopting cr-al alloy,HRC 65-72, the roughness of working surface 0.1μM-0.2μM.
O-ring:Adopting the raw material of butadiene-acrylonitrile rubber which is the copolymerization of butene and acrylonitrile into produce. That has better oil resistance and high-temperature resistance.
The Carrier Roller surface hardness ranges from HRC 50 to 56 ,depth from 8mm to 12mm.
A thorough study of the original drawing presenting the performance requirements of the various OEMs (Original Equipment Manufacturers) will allow us to manufacture all the different types of sprockets available on the market. The best solution will be applied to our production line after rigorous analysis of the drawings and heat treatment.
Carrier Roller
Carrier Roller is an important part of belt conveyor, with many kinds and large quantity. The function is to support the belt, reduce the running resistance of the belt, and make the verticality of the belt not exceed a certain limit to ensure the smooth running of the belt.
According to their uses, the rollers are classified as centering rollers, buffer rollers, grooved rollers and parallel rollers. The function of centering rollers is to correct the runout of belt conveyor, usually rotary slotted centering rollers are installed on the heavy load section of the conveyor, and parallel centering rollers are installed on the no-load section. Buffer rollers are applied to the tailstock according to the actual situation. When receiving material, it can reduce the impact of material on the belt, which is conducive to the service life along the long belt. Slotted roller is generally composed of two side rollers and one flat roller, the slot angle is generally 30 degrees, for the detachable belt conveyor, the three rollers of slotted roller are hinged together with each other, so it is called articulated roller. The parallel roller is generally a long roller, which is installed at the lower end of bearing pressure, so it is called the lower roller.
The rollers are divided into steel and plastic rollers in terms of material. There are three kinds of bearing seats for the rollers, such as cast iron and steel plate stamping and phenolic plastic.
The sealing of the rollers is divided into steel and plastic. Their seals are filled with grease inside. The good or bad of the roller directly affects the power consumption of the belt conveyor and the life of the belt. Therefore, reliable dustproof seal and good lubrication are important criteria for use.
The quality of the rollers is especially important as they account for 35% of the total cost of a belt conveyor and generate more than 70% of the resistance.The top rollers maintain the track link at its optimum height to ensure a tight binding of all the different elements for more efficient machine operation. A thorough study of the OEMs (Original Equipment Manufacturers) original drawing representing the upper roller required performances, will allow us to manufacture all the different types of carrier rollers available on the market. The best solution will be applied to our production line after rigorous analysis of the drawings.
