We have been facilitated with an advanced infrastructure that plays an important role in our successful operations in this domain. It consists of integrated manufacturing, quality control, research & development, and warehousing departments, which aid us in delivering a defect-free range of products to our customers. The machines, equipment, and tools installed at the infrastructure facility are highly sophisticated. Further, to keep pace with the changing market trends, we upgrade our machinery set up on a regular basis.
Raw material, SAE 52100 Steel conforming to international standards is used for manufacturing AAC Group bearings and same steel is used for all the bearing components like races, cages, and rolling elements. All the cages are composed of CRC material and brass as per international standard specification.
Forging is a metal shaping treatment that works through the forces of heat and impact to give the desired shape to the metal. The process is performed on SAE 52100 Steel so as to deliver a perfect shape. Anneling is an association of heating and cooling treatment performed on the bearings so as to enhance the ductility of the bearings. This makes the bearings more workable with regards to molding them to any desired shape.
Forged material is further used to do turning with the help of automatic CNC Machines. These machines are known worldwide for reliable operation and increased productivity when it comes to manufacturing complicated components with highest degree of accuracy and perfection.
All the components of the bearing including Inner & Outer races, rings and the rollers are heat treated to provide resistance to wear and tear. Both the inner and outer races are hardened to 60 ± 2 HRC as per international standard. The hardness of the races as well as the rolling elements is further checked and tested using a hardness tester.
The grinding process undergoes four stages namely:
Face Grinding: In the face grinding process, duplex machine is used. Components are checked for size variations, flatness, roughness, parallelism and burning.
OD Grinding: In this stage material is checked for 2 point ovality, 3 point ovality, roundness and roughness.
Track Grinding: In this stage of the grinding process the size of the track is checked along with curvatures, taper, eccentric, roughness, 2 point ovality and 3 point ovality.
ID Grinding: In this stage, an electronic measuring system known as marposs system is used to control size variation. The system checks for size precision in terms of ovality, roughness, roundness and other errors.
After the grinding process, we reduce Roughness Average (Ra) value on Track with the help of Honing & Lapping machine & maintain RA value which provides super finished bearing components.
