Introduction
Bearing chock plays an important role of fixing bearing and bearing weight. It is the core part of rolling bearing. Its main function is to support the whole bearing structure.
Bearing chock works under low speed and heavy load for long time. So its reliability is the most important feature. To achieve this feature, it must require good quality of bearing chock.
Our main material for the bearing chock is similar as following
| Standard Specifications for Cast Steel SCW480 |
| Country | Standard | Grade |
| China | GB/T 11352-1989 | ZG20SiMn |
| United Kingdom | / | / |
| USA | AISI/SAE | UNS J02505 |
| Japan | JIS-G5102 | SCW480 |
| Germany | DIN 17182 | GS-20Mn5 |

Advantage
1. Fine material, high level of wear resisting
SHANGHAI SPECIAL METAL CO., LTD uses SCW480 to produce bearing chock, to ensure products' quality. Through the test of practice, bearing chocks produced by SHANGHAI SPECIAL METAL CO., LTD can work well under long-time, heavy load operation with small wear loss.
2. Equipped with monitoring devices, can get operation condition at any time
Below bearing chock, there's an oil leveler. Operator can view oil level at any time, supplement oil in time, avoid poor lubrication and bearing damage lead from oil lacking.
3. Reasonable structure, good for long-time and stable operation
Removed outside top cover, this design avoids dusts go into bearing box, improves bearing's working life, and secures its work.
4. Holes of cylinder-oil with the degree of finish Ra 0.02
Production Process
1. Wooden pattern Production
2. Molding
3. Pouring
4. First cleaning
5. Heat treatment - grinding (inspection)
6. Rough machining (inspection)-finishing machining (inspection)
7. Packing-delivering
Quality Assurance
The fabrication route is governed by the provisions of the implemented Quality System ISO 9001: 2000. The standard documentation ensures the full traceability of every process step:
Manufacturer test certificates according to DIN EN 10.204 § 3.1 including chemical composition, mechanical properties and non-destructive examination;
Dimensional check supported with a "as-built" sketch;
Record of the heat treatment chart
China Special Metal Group Limited (CSM), a supplier of metal material & machinery products, devotes to offer high quality of castings, high-precision machining products, welded fabrications and forgings to valued customers from all over the world. Meanwhile, we offer the design engineering and turnkey project as well.
Our group owns four mainly manufacturing bases. Casting bases in Xinxiang and Yiyang; The welding fabrication base in Wuxi; Special alloy base in Xi'an. Our Shanghai base is the commercial and engineering center. We have our own ISO 9001 certificate.
We have 2 sets of 30 Ton alkaline electric arc furnace; 8sets of transferring ladle with capacity of 35ton, 50tons, and 75tons; 2 sets of baked charter; 4 sets of large heat treatment furnace and the supporting facilities including oxygen generation station, air compression plant, natural gas station, CO station and 22 sets of lifting equipment machines. The lifting capacity reaches 200tons. We own 5 sets of large-scale molding equipment. Meanwhile, we also have the GS1000 vacuum direct reading spectrometer made by OBLF and other inspection equipments like carbon sulfide high-speed analyzer, microcomputer three elements of high-speed analyzer, digital ultrasonic flaw detector, multipurpose magnetic powder flaw detector such as chemical equipment, except that we also own leveraged universal strength tester, SAC thumping machine. Simulating the casting process by the CAE software to ensures the new quality level castings. All the castings are process by arc gouging, carbon dioxide gas gouging, shot-blasted in order to get the surface quality.
Our products include Metallurgical equipment, Cement & Mining machinery. The castings singe weight is up to 120MT. The main products are casting ladles, slag pot, ingot moulds, mill housings, chucks, girth gear & wheel for cement and mining machinery, grinding table and grinding roller for mills, case and covers for pumps, body and beams for all kinds of machine.
