GB DIN Stainless Steel Forged Steel Rings / Bearing Outer Ring For Auto Parts PT Test

Descrition:

With max unit weight 12and max outer diameter 300mm we are able to manufacture kinds of 

ringlike&cylindrical forgings including non-standard flanges, wind power flanges, gear rims, 

wind power main shafts, etc. Which are extensively applied in Industries of petroleum, machinery, 

engineering, harbor machinery, gear, reducer machinery, hydraulic machinery and wind 

generating set etc. 

(1). Among the free forgings carbon steel forgings are generally the better choice for the sake
 of its high tolerance strength, hardness, yield strength, elongation, crush resistance, torsion 
resistance and shearing resistance. 
(2). We can forge forgings according to weight ranges from 100kg-12T
(3). They are mainly applied in machinery, chemical and petroleum industries, mould, shipping, 
transportation, agriculture, pipeline, metallurgy, GI, etc.
(4). We have professional UT center and every year we have less than 2 complaint cases from 
customers and products qualification rate over 99%. 
(5). We were certificated to ISO9001: 2008 and passed 9 countries\' authentication of 
\"Classification Society\". 
(6). We usualy use material of steel type of GB, ASTM, AISI, ASME, DIN, BS, EN, etc. According
 to customers\' different requirements.
(7). Main material are CK45, AISI 4140&4130, 5CrMnMo, 40Cr, 42CrMo, 20Cr2Ni4, 5CrNiMo, 
15CrNiMo, 20CrNiMo, 35CrMo, 40CrNiMo, etc. 
(8). Regularly, we accept processing on giving materials. 
(9). We generally produce forging blank with rough machining range from 150kg to 20t.
(10). According to practical situation and customers\' clear requirements we can render 
excellent heat treatment. 
(11). As for the third party inspection, we will try out utmost to satisfy our customers\' request. 
(12). If you have office in China, pls kindly pay a visit to our factory, and we are with much

Application:

1. Any striking on and collision with roll rings is strictly prohibited.

2. When installing the whole assembly of roll rings, the clearance of the bearings in relation to the casings should be on the tighter side .

3. The precision of rotation of the whole assembly ( circular runout and end runout ) should be kept within ±0.05mm.

4. The fitting -in
