Two decades of turning steel into trust.
From the family's first workshop in 2006 to a group with Sumangal Industries under its wing — the story of Radheshyam Rollers is the story of doing one thing exceptionally well.
Built by hand. Measured by micron.
2006
The year the family's precision journey began — today the Radheshyam Rollers group, parent of Sumangal Industries.
The Vanpariya family's journey in precision manufacturing began in 2006 — built on a single conviction: a bearing is only as good as the rollers inside it. In 2021 that experience became Radheshyam Rollers, today the parent company of Sumangal Industries, with a dedicated roller unit at Padvala, Rajkot — cutting, heat treatment, grinding, sorting and inspection all under one roof.
Dharmik and Renish Vanpariya run operations and sales with the same promise the family started with: every roller measured, every batch inspected, every delivery on time.
Our customers are bearing manufacturers across India who cannot afford variation. That responsibility is what gets our machines switched on every morning.
Values ground into every roller.
Precision First
A roller is only as good as its geometry. Every decision on our floor starts with tolerance.
Consistency
The 10,000th roller in a batch measures like the first. That is what our process is built for.
On-Time Delivery
Bearing lines cannot wait. We plan capacity so committed dates are dates you can build on.
Partnership
Three directors, direct phone lines. When you call Radheshyam, you talk to a decision-maker.
Five reasons buyers stay for decades.
From raw steel to final inspection, all six stages happen under one roof — no outsourced steps, no loss of control over quality or timelines.
Centerless grinding and 100% sorting hold diameter variation within microns, so our rollers drop straight into your bearing assembly.
Hardness, geometry and finish are checked on every single batch — with records you can trace back any time.
You buy from the factory floor, not a trading desk. Better prices, faster answers, honest lead times.
Send a drawing or a sample — we develop special profiles, angles and sizes with full dimensional reports on the pilot lot.
