High Precision Cemented Carbide Roller Polished Surface Tungsten Carbide Thread Roller
Applications
Tungsten Carbide is not affected by changes in the environment or external temperature so these durable rollers can be used in either extreme heat or extreme cold. Tungsten carbide rollers are valued for their hardness and resistance to corrosion and, since they can withstand an elevated level of stress, they are the ideal choice for clients in the aeronautic and aerospace industries, the automotive industry and the bearings industry. They are often found in power steering columns or transmission and navigation equipment and can also be used for vibro finishing.
We manufacture and supply tungsten carbide rollers for many clients worldwide for years. Competitive price, excellent roller properties and best service are the guidelines we always insist in doing business. The tungsten carbide rollers we can manufacture are with various specification and tungsten carbide grades. Besides, we can also manufacture tungsten carbide rollers according to customers’ special design.
Tungsten carbide roll ring is a kind of tool material which consists of tungsten carbide and cobalt with high hardness and wear resistance. To take advantage of high wear resistance, long life and high efficiency of cemented carbide roll rings during the high speed rolling, attention should be paid as follows when purchasing and using cemented carbide roll ring.
