BIS Certification for Double Row Cylindrical Roller Bearings IS 6458

Double-row cylindrical bearing, for when high radial loads and rigidity, as well as space, are required, go for double-row cylindrical bearings. These bearings are intended for high radial load handling and are ideal for precision indexing and low-friction rotation. The bearings are widely used in gearboxes, electric motors, steam turbines, cranes, compressors and other kinds of machines.

Since their performance is to a large extent connected to industrial use, it is of utmost importance that they are manufactured according to strict, well-established standards. The BIS Certification of these products are compulsory to provide safety and quality to the consumers.

 

Overview of Double Row Cylindrical Roller Bearings Certification

Whenever industries require high radial load capacity and rigidity, without compromising on the space requirement, double-row cylindrical roller bearings come into play. The bearings are suited to sustain extreme load levels while keeping almost perfect alignment with minimum lateral friction-and these qualities make them specially suited for gearboxes, electric motors, compressors, and heavy-duty machines.

 

Being so pivotal in industrial performance, there have to be strict quality standards that they comply with. For this Bureau of Indian Standards (BIS) has laid down IS 6458, specifying the technical and dimensional requirements for these bearings.

 

Key Specification of IS 6458

The double row cylindrical roller bearings IS 6458 covers:

• Non-locating bearing (supports radial loads only and permits axial displacement).
• Two-direction locating bearing (controls radial and axial loads in both directions).

 

The interchangeability, high-quality performance, and uniformity of bearing types of bearing designs for industrial applications essentially depend upon the standard. 
General Requirements: All other conditions, such as material, hardness, surface finish, and coating, are governed under IS 6453 (technical supply conditions for rolling bearings).

 

Designation System: IS 6458 provides a more comprehensive and standardized designation system, including:

• Bore diameter
• Configuration code
  -Dimension series
  -Tolerance class (e.g., P5)
  -Radial clearance group (e.g., C2, C3)
  -Special features, e.g., tapered bore (XK)

 

• Scope: Outlines the scope of the standard, specifying what types of double row cylindrical roller bearings are covered.
  Dimensions and Tolerances: The standard gives details of the dimensions, tolerances, and other parameters of the bearings, so that there can be uniformity and interchangeability.

 

• Performance Requirements: The performance requirements given in the standard include load capacity, speed limits, and lubrication requirements.
  Materials and Manufacturing: The standard gives the appropriate materials and acceptable manufacturing process for the bearings, to enable them to meet the quality standards.

 

BIS Certification Scope of Double Row Cylindrical Roller Bearings

Certified BIS (Bureau of Indian Standards) for double-row cylindrical roller bearings under IS 6458 assures that the quality of the bearings and their safety and performance levels are satisfied to Indian requirements. The certification model includes product testing, factory audit, and continuous surveillance for compliance with the IS 6458 specification.

 

Process for Getting BIS Certification for Double Row Cylindrical Roller Bearings IS 6458

Let’s break down the steps to get Product Certification for IS 6458:

• Application Submission: The manufacturer kicks things off by sending an application to BIS, which includes details about the product and the factory where it’s made.
• Product Testing: Random samples from the production batch are picked and tested in BIS-approved labs to ensure they meet the IS 6458 standards.
• Factory Audit: BIS will then pay a visit to the factory to inspect the manufacturing process, check the quality control system, trace raw materials, and evaluate testing facilities.
• Grant of License: If everything checks out and the factory can consistently produce products that meet BIS specifications, the manufacturer will receive a license to use the Standard Mark as outlined by BIS.
• Ongoing Surveillance: BIS keeps a close eye on things with regular inspections and by taking samples from the market or factory to ensure continued compliance with IS 6458

 

The BIS certification process can be completed to certify the product for both Indian & foreign manufacturers: 

• BIS Mark Certification Process for Indian Manufacturers
• BIS Mark Certification Process for Foreign Manufacturers

 

What are the timelines for Double Row Cylindrical Roller Bearings?

India has a variety of Product certification timelines tailored for different types of producers. For instance, Indian manufacturers can typically expect their BIS Certifications to be issued within about 30 days, while foreign manufacturers may have to wait up to 180 days for their certifications to be released. To get Product certification instantly you need a BIS consultant.

 

Documents Required Under BIS Certification of Double Row Cylindrical Roller Bearings

Let’s take a closer look at the key documents needed for BIS Certification of Double Row Cylindrical Roller Bearings:

• Application Form: This is a must-have document provided by BIS. It includes essential details about both the applicant and the product.
• Product Technical Datasheet: This should contain all the technical specifications of the double row cylindrical roller bearing.
• Manufacturing Process Flow Chart: A visual representation that outlines the manufacturing process, detailing the raw materials used and how they come together to create the final product.
• List of Testing Equipment and Machinery: This is a separate document that lists all the equipment and machinery utilized for testing purposes.
• Test Reports: You’ll need to include test reports from a BIS-approved or recognized testing lab, demonstrating that the bearing has been tested and meets the required standards.
• Business License (and Trademark License): These documents confirm that the applicant is legally authorized to manufacture and sell the products.
• Authorization Letter (if applicable): If a non-manufacturing applicant is applying on behalf of the manufacturer, an authorization letter will be necessary.
• MSME Certificate (if applicable): Micro, Small, and Medium Enterprises (MSMEs) must also provide their registration certificate.
