Understanding the relevance of a Quality Management System, V.KAN.EXPORT has undertaken ISO 9001-2008 & ISO-TS 16949:2009 certification. Our strong quality management processes have helped us attain cost savings, driving improved efficiency & productivity, as product or service deficiencies are tracked. This helps us reduce waste, inappropriate or rejected work & fewer complaints. Hence, more customer orders are directly met consistently on time & to the accurate specifications.
Our Bearings are according to ISO standards & the tolerances are of normal class Po (ABEC) Bearing clearances are normal clearance. (But upon specific requirement we can produce C2, C3 or C4 clearance bearings.)- Inner Diameter, Outer Diameter, Width, Roundness, Run outs, Radial Clearance, Face Parallelism all are as per ISO. (International Standard Organization).We have quality equipments like roundness tester, surface finish measuring equipment, profile projector, calibrating equipments & other accessories including Pneumatic Comparators in our standard room to support the quality parameters. Our quality is an integral part of our culture & every effort is made to ensure that the customer gets value for money. The company has skilled employees at all levels to bring their experience & expertise in to the manufacturing of quality bearings. Chemical composition analysis of raw material is done before forging of each batch. Micro structure & HRC is checked after annealing & heat treatment. Ra value of each batch is checked at grinding stage. 100% inspection of ID, OD, Width, Radial Clearance. View Inspection & Testing section.

Raw material, SAE 52100 Steel conforming to international standards is used for manufacturing CAN bearings & same steel is used for all the bearing components like races, cages & rolling elements. All the cages are composed of CRC material & brass or glass filled polyamide as per international standard specification.
The chemistry of the SAE 52100 Steel is checked, tested & verified through metallurgical testing performed by expert metallurgists. Before commencing the actual manufacturing the steel to be used is thoroughly inspected
Forging is a metal shaping treatment that works through the forces of heat & impact to give the desired shape to the metal. The process is performed on SAE 52100 Steel so as to deliver a perfect shape. Annealing is an association of heating & cooling treatment performed on the bearings so as to enhance the ductility of the bearings. This makes the bearings more workable with regards to moulding 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 & increased productivity when it comes to manufacturing complicated components with highest degree of accuracy & perfection.
All the components of the bearing including Inner & Outer races, rings & the rollers are heat treated to provide resistance to wear & tear. Both the inner & outer races are hardened to 58 To 62 HRC as per international standard.
The hardness of the races as well as the rolling elements is further checked & tested using a hardness tester.
Dimensions of a bearing play a vital role in the performance & usability of the bearing. This includes the inner diameter, the outer diameter & the diameter of the bearing width. All these three conform to international standards when it comes to verifying the bearing dimension at CAN Bearings.
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.
* OD Grinding: In this stage material is checked for 2 point ovality, 3 point ovality, & roundness.
* 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 & 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 & 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.
After the super finishing process, all the races & rolling elements are washed & cleaned ultrasonically to clear off all the remaining dirt & dust. Thereafter, based on the specific customer requirements, the components are assembled with precision & excellence using Fully automatic assembly line.
After assembling the components, bearings are neatly & securely packed under hygienic conditions. The manufactured bearings are first oiled to ensure protection against varied atmospheric effects & then wrapped securely in plastic bags. Further to that, these are packed in individual boxes which are collectively packed in a master box for transportation.
