Who we are
A family-run factory obsessed with roundness.
Since 2006, the Vanpariya family has done one thing and done it well — precision taper rollers for the bearing industry. Every stage, from raw 100Cr6 steel to final inspection, happens under our own roof in Rajkot, Gujarat: the machine-building heartland of India.
End-to-end in-house process
From raw steel to final inspection, all six stages happen under one roof — no outsourced steps, no loss of control over quality or timelines.
Micron-level tolerances
Centerless grinding and 100% sorting hold diameter variation within microns, so our rollers drop straight into your bearing assembly.
Every batch inspected
Hardness, geometry and finish are checked on every single batch — with records you can trace back any time.
Direct manufacturer pricing
You buy from the factory floor, not a trading desk. Better prices, faster answers, honest lead times.
Custom development from drawing
Send a drawing or a sample — we develop special profiles, angles and sizes with full dimensional reports on the pilot lot.
What we make
Rollers engineered for the raceway.
Quality assurance
Measured in microns, proven on every batch.
- Rockwell hardness tester on every heat-treatment batch
- Digital micrometers & dial gauges with micron resolution
- Profile projector for taper angle & crown verification
- Surface roughness measurement on finished lots
- Visual & crack inspection before packing
- Dimensional report supplied with development lots
How it's made
Six stages. One roof. Zero shortcuts.
Precision Cutting
Blanks cut to accurate lengths with smooth edges, keeping material flow consistent batch after batch.
Heat Treatment
Controlled hardening and tempering to 58–62 HRC for a tough core and wear-resistant surface.
Precision Grinding
Centerless and profile grinding hold the taper angle, crown and micron-level diameter tolerance.
Automated Sorting
Every roller passes through sorting for uniform sizing — no mixed diameters, no surprises.
Final Inspection
Dedicated inspection of hardness, geometry and finish before packing, with traceable batch records.
