- Rolex Rings began with a passion for engineering and limited capital, starting as a small partnership forging bearing rings in Rajkot. Over five decades it has grown into one of India’s largest precision forging and machining companies, now serving 57 customers across 14 countries. The recurring approach is simple: invest early in high-speed forging technology that rivals cannot easily match, build relationships with global bearing and automotive giants that last decades, and then use the cash flows from those relationships to deepen the manufacturing process - moving from raw forgings to fully machined, ready-to-assemble components.
Business segments
A single precision-engineering engine built on two product families - bearing rings and automotive components - that share the same forging and machining backbone, sold to the same type of global customer.
1. Bearing rings: the foundation that built the company
Rolex supplies forged and machined rings to virtually every global bearing multinational, holding an estimated 30-35% share of the domestic bearing ring market and acting as the preferred supplier in its addressable segment.
- The original core - bearing rings were the company’s first product, beginning with traditional forging in the 1980s and scaling dramatically after the purchase of a Japanese high-speed hot former running at 170 strokes per minute, which made Rolex one of India’s largest manufacturers of hot forged rolled rings.
- Rings for every bearing type - the range spans inner diameters from 20 mm to 900 mm and individual ring weights from 10 grams to over 163 kg, covering tapered, cylindrical, spherical, deep groove, and railway bearing types.
- Supplies the top five - the five largest bearing manufacturers hold roughly 80% of the domestic bearing business, and these are Rolex’s main customers; for some large accounts, Rolex supplies 60% of their total ring requirement.
- Forging is winning over tube - forged bearing rings command a premium over tube-based rings for high-load critical applications, and a major domestic customer is shifting 60-70 components from the tube route to the forging route, expanding the addressable market.
2. Automotive components: the growth engine
What began as a diversification during the post-restructuring recovery has grown to nearly half of revenue, spanning every vehicle category from two-wheelers to heavy trucks - and the shift toward machined, higher-value parts is pulling margins upward.
- Full vehicle spectrum - the product range includes transmission parts like gear blanks and ring gears, chassis parts like wheel hubs and output shafts, plus CVJ and differential components, with piece weights from 200 grams to 125 kg.
- Started with a global OEM - the auto vertical was built from 2014-15 by winning business with a leading global OEM, then expanding across passenger cars, commercial vehicles, off-highway equipment, and industrial applications.
- EV and hybrid parts earn more - components for electric and hybrid vehicles - transmission parts, gear cases, wheel hub units - involve more critical operations and deliver margins a couple of percentage points better than traditional bearing rings or low-value-added auto parts.
- Europe is the new frontier - European auto component revenue grew 25% in FY26, and 60% of all new business nominations came from European customers, including a recent win with a French OEM.
- Taking over customer capacity - one customer has declared it will shut its in-house forging facility, and Rolex is preparing to absorb that volume, supported by two additional vertical forging lines already on order.
Vertically-integrated manufacturing: the shared backbone
Every product - bearing ring or auto component - moves through a single integrated chain of tool-making, forging, heat treatment, cold rolling, machining, and surface treatment, all under one roof in Rajkot.
- 26 forging lines, 625 machining spindles - the forging infrastructure has a combined capacity of 1,65,000 tonnes per year using high-speed hot formers from Sakamura and Hatebur for volume parts, plus vertical forging lines from Mitsubishi, SMS Meer and others for medium and lower-volume work; machining capacity exceeds 75 million pieces per year across CNC turning, VMC, broaching, hobbing, and gear-shaving machines.
- Heat treatment at scale - continuous cast link furnaces handle 800 tonnes per month for smaller products, while sealed quench furnaces process 1,000 tonnes per month for products up to 35 inches in diameter, all CQI9 certified and SCADA-automated.
- Cold rolling saves material - near-net shapes - cylindrical, tapered, spherical - are formed up to 160 mm outer diameter, improving yield before machining even begins.
- In-house tool and die - the company makes its own tooling using CAD/CAM, high-precision CNC, EDM, and wire-cut equipment, which means new component development does not depend on outside toolmakers.
- Port proximity and a machining cluster - the Rajkot site sits roughly 250 km from Mundra and Pipavav ports, and the region’s network of smaller machining units provides pre-machining capacity and trained manpower.
Global customer partnerships: the moat
Seven of the top ten customers have been with Rolex for over 15 years, and once a relationship is stable, customers rarely switch - because the tooling investment is sunk, the qualification cycle is long, and the supply record is clean.
- Decade-long agreements - most major customers operate under long-term agreements of five to seven years, and the top five customer groups accounted for around 61% of revenue.
- Sole supplier on many parts - for numerous components, Rolex is the only supplier to a given customer group, partly because customers pay significant tooling costs for development and have no incentive to duplicate.
- Awards stack up - the company has won a Supplier Quality Excellence Award every year from 2014 to 2022, a Zero PPM Award for zero-defect supply, and Green Category Supplier status - the highest supplier classification.
- Tariffs tested the bond - when US duties jumped from 3% to 53%, a major American customer temporarily shut a plant and supply to that program went to nearly zero; Rolex did not lose a single US customer, and all programs remain intact.
- Cost pass-through is built in - raw material price fluctuations pass to customers with a one-quarter lag, and overseas customers absorb freight and commodity inflation on a one- or two-quarter lag, insulating the company from input-cost swings.
Group structure and partners
Rolex Rings is a standalone listed company with no subsidiaries or joint ventures, controlled by the founding Madeka family and debt-free after clearing its final restructuring obligation in March 2026.
- Single entity, no subsidiaries - the company has no subsidiaries, joint ventures, or associate companies, and is listed on both NSE and BSE following its IPO in mid-2021.
- Promoter family holds 52% - nine members of the Madeka family together hold just over half the company, with the Chairman and Managing Director and two Wholetime Directors drawn from the family.
- Debt-free milestone - after entering Corporate Debt Restructuring in 2013, the company fully exited CDR by 2022 and paid its final Right of Recompense obligation of Rs. 101 crores in March 2026, leaving it completely debt-free with no lender covenants or restrictions.
- Rivendell PE backed the scale-up - private equity firm Rivendell PE invested Rs. 150 crores during the 2007-2009 period, coinciding with the commissioning of Unit 2.
- Industrial park diversification - in December 2021, the company signed an MoU with the Gujarat government to develop a Textile and Apparel Park, an IT Park, and a Toy Park in Gondal district with a proposed investment of Rs. 1,500 crore, marking a move into industrial park development.
