BIS Certification for Double Row Cylindrical Roller Bearings IS 6458:1972

Double row cylindrical roller bearings use two rows of short cylindrical rollers running in raceways on the inner and outer rings. Cylindrical rollers make line contact (rather than the point contact of balls), so the load is spread over a larger area - giving these bearings exceptionally high radial load capacity and stiffness in a compact, precise package.

Their high rigidity and running accuracy make them a favourite for machine tool spindles, as well as heavy gearboxes, rolling mills, large electric motors, and precision industrial drives. Because they support critical, high-precision machinery, they are covered under the Bearings (Quality Control) Order, 2025 and now require the BIS ISI Mark under IS 6458:1972.

Because double row cylindrical roller bearings often sit at the heart of high-value machine tools and rolling mills, buyers in these sectors are especially strict about certified quality - an uncertified bearing simply will not be accepted. Securing the ISI Mark under IS 6458:1972 therefore opens doors to premium OEM and capital-equipment contracts, both in India and for exporters supplying Indian customers. Standphill India manages the entire certification - from picking the right scope and readying your precision-grinding and inspection setup for the BIS audit, to lab testing and final licence grant - as one smooth project.

BIS-recognized laboratories evaluate double row cylindrical roller bearing against IS 6458:1972 for:

• Dimensions & tolerances - bore, OD, width, roller geometry across both rows
• Material & hardness - bearing steel quality, roller and raceway hardness
• Radial clearance - within specified internal-clearance groups
• Running accuracy - radial runout for precision running
• Load rating - dynamic & static radial load performance
• Surface finish & cage integrity - roller guidance, raceway finish

Typical timeline: 8-14 weeks. Foreign manufacturers (FMCS) may take longer due to overseas audit scheduling.

• BIS application form (Manakonline)
• Factory registration proof
• MSME / Udyam certificate
• Manufacturing process flow chart
• List of machinery (grinding, heat treatment, assembly)
• List of in-house testing equipment
• Bearing steel grade details
• Product range & size designations
• Trademark / brand registration
• AIR appointment (foreign mfr.)
• BIS-recognized lab test report

Being an MSME under the Bearings QCO 2025 gives you two significant advantages: a longer compliance window (9 months for Small, 12 months for Micro) AND substantial discounts on BIS ISI Mark marking fees - the per-unit fee paid to BIS based on your annual production or import volume.
