This is the first large diameter longitudinal submerged arc welded (LSAW) pipe production line in China .The mill adopts continuous axis contorting J-C-O(J-ing, C-ing and O-ing)process with characteri…
We can produce steel pipe, steel tube, square and rectangular steel hollow sections, High frequency steel pipe, Erw steel pipe, galvanized steel pipe, carbon steel pipe, balck steel pipe, hot roll ste…
Ball roller ,thrust bearings,load and its axial cord are formed a certain angle ,from one raceway pass away another.So,this kind of bearings are different from other thrust bearings.Ball roller thrust…
Liner motion bearing consists of sleeveed outer ring,multi-row balls and a retainer.It can make liner reiprocating displacement on a matching shaft.The more the ball rows are,the less the friction for…
Spherical.plain bearing composed of inner ring and outer ring is able to rotate in 3 dimensions and to bear radial,axial,or radial-axial combined load(depend on its construction) within slow speed.
We can makes and markets cold-drawn and hot rolled seamless steel pipes and cold-drawn special-section seamless pipes which are widely applied in the industries of petrochemical, boiler, automobile, m…

The pillow block ball bearing is composed of a single row deep groove ball bearings with seals at both sides and spterical outside surface and a housing ,suitable for simple support,widely used in var…
This Standard applies to seamless precision steel tubes; and, in compliance with ISO/DIS 3304, those tube dimensions have een selectied from the range of manufactura le tu e dimensions which are mainl…
Needle roller bearing is roller bearing with cylindrical roller,compared with its diameter,the roller is slender and long.This roller is called needle roller.Althougn it has smaller cross section,the …
Angular contact ball bearings are able to support radial load and axial load.As single row angular contact ball bearings can only support axial load in single direction ,matched pair of bearings,prelo…
This type of bearing is separable .As their rollers linearly come into contact with inner ring and outer ring with less coefficient of friction,these bearings have very good capacity of radial load,su…
With the same center as the bearing,the spherically formed outer ring raceway can make self-alignment.Their rolling elements linearly come into contact with the raceways of inner ring and outer ring.T…
