The ISI Mark is a small sign with a big meaning. When a buyer sees it on a product, the buyer knows that the product follows the Indian rule book. If you make cylindrical rollers, or bring them into India, you will meet this mark sooner or later. This guide explains it for both manufacturers and importers, in very simple words.
What Is the ISI Mark?
The ISI Mark is the Standard Mark of the Bureau of Indian Standards, also called BIS. It can be used only by a company that holds a BIS license. For cylindrical rollers, the rule book is IS 9202:2020. It covers the size, weight, steel material, heat treatment and shape accuracy of the rollers.
Here is the good news. The BIS ISI Mark for Cylindrical Rollers for Rolling Bearings is not just a sticker. It is proof that your factory can make good rollers again and again.
Why Rollers Need Such Care
Cylindrical rollers sit inside bearings in motors, gearboxes, pumps and heavy machines. They carry heavy loads all day. If the size is off by a tiny amount or the steel is weak, the bearing can get noisy, hot and damaged. A machine stopped for repair costs far more than the roller itself. That is why the rule book is strict.
Guide for Manufacturers
If you make rollers in India, your path looks like this:
- Study the standard and compare it with your roller drawings.
- Prepare your factory, lab and records.
- Register on the BIS Manak portal.
- Send samples to a BIS-recognized lab.
- Submit your application with test reports and papers.
- Pass the BIS factory inspection.
- Receive your license under Scheme-I and start using the mark.
For Indian manufacturers, the main government fees are INR 1,000 for the application, INR 7,000 for the audit and INR 1,000 for the license. Testing and marking charges are extra, and fees can change, so check the latest BIS rates.
Guide for Importers
If you import rollers, the first thing to know is that you should buy from a maker who holds a BIS license. The foreign maker must apply to BIS and name an Authorized Indian Representative, who talks to BIS on the maker's behalf. For this role, many companies look for a BIS Agent for Cylindrical Rollers for Rolling Bearings who knows the process well.
As an importer, you can ask your supplier for three things:
- A valid BIS license number
- A copy of the license papers
- Clear marking on the roller or its packing
The draft government order leaves out a few cases. These are rollers imported inside a finished product, rollers used to build products only for export, and up to 200 pieces a year for research. Keep your records neat if you use any of these.
Papers You Will Need
Whether you make or import, good papers save time. For BIS For IS 9202:2020, a typical manufacturer keeps these ready:
- GST certificate and factory address proof
- List of machines, process flow chart and factory layout
- List of test equipment and calibration certificates
- Raw material list, supplier details and steel test certificates
- Trademark or brand proof
- Consent letter from a BIS-recognized lab
- Name of the person who will speak to BIS
Foreign makers also need an agreement with the representative, a nomination form and some undertakings.
What Tests Are Done?
- Material: steel grade, chemical mix and cleanliness
- Size: diameter, length, roundness and edge shape
- Strength: hardness and wear resistance
- Surface: roughness, cracks, pits and rust
- Batches: random sampling and tracking from raw material to finished roller
How to Put the Mark on Your Roller
After you get the license, the mark must be clear and long-lasting. You can stamp or print it on the roller or on its packing. Along with the mark, show these details:
- The standard number
- Your CM/L number given by BIS
- Your name or trademark
- Batch number or date
How Long Does the License Last?
A license is usually first given for 1 to 2 years. You must renew it before it ends. BIS can visit your factory again and pick samples from the market. If samples fail or rules are broken, the license can be suspended or cancelled.
Deadlines in the Draft Order
The draft gives time after the order is published: 12 months for medium and large units, 15 months for small units and 18 months for micro units. It was still a draft when we checked, so please read the final notice before you plan.
Mistakes to Avoid
- Buying rollers without checking the supplier's license
- Missing calibration certificates
- Weak records of raw material
- Wrong product scope in the application
- Forgetting to renew on time
