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.
