Get BIS certification for Cylindrical Rollers for Rolling Bearings under IS 9202:2020.

Cylindrical rollers are the load-carrying hearts of cylindrical roller bearings. Where a ball touches its raceway at a point, a roller touches along a line - which is why roller bearings carry several times the radial load of a same-size ball bearing. Each roller is headed or turned from bearing steel, hardened, then ground and superfinished; modern rollers carry a subtle logarithmic crown on the rolling surface that spreads stress evenly and prevents the edge-loading that kills bearings early.

IS 9202:2020 specifies the dimensions, tolerances and surface requirements for these rollers - diameter and length tolerances, diameter variation within a roller and across a set, profile and surface roughness. Roller quality decides the load rating printed on every cylindrical roller bearing, which is why rollers are covered as a separate product under the Bearing Components and Accessories (Quality Control) Order, 2025 and now require the BIS ISI Mark under IS 9202:2020 - distinct from the finished-bearing licence under IS 6457:2024.

Roller makers sit one tier below the bearing brands - supplying OEM bearing plants in India and abroad. Once the QCO bites, every Indian bearing manufacturer will demand ISI-marked rollers from their component vendors to protect their own compliance, making the IS 9202 licence a commercial survival requirement. Standphill India prepares your grinding and superfinishing line for the Scheme-I audit, coordinates roller testing, and - for integrated plants that also assemble bearings - synchronises the IS 9202 component licence with the IS 6457:2024 finished-bearing licence as one project.

BIS-recognized laboratories evaluate cylindrical rollers for rolling bearings against IS 9202:2020 for:

• Roller diameter & tolerance - diameter within IS 9202:2020 limits
• Roller length & tolerance - length accuracy for the size series
• Diameter variation - within a roller and across the roller set
• Profile & crowning - rolling-surface profile to prevent edge loading
• Surface roughness - Ra of the rolling contact surface
• Material & hardness - bearing steel composition and through-hardness

Typical timeline: 4-6 months for Indian manufacturers; 8-14 months for foreign manufacturers (FMCS) - against a 6-month general QCO deadline, start immediately.
