Have you ever paused to think about what powers your scooter or motorcycle behind the scenes? It’s not just the engine—those small links in the chain and sprocket system also play a massive role. And one name stands out in this field: Rockman Industries.
Let’s talk about how Rockman, which began with humble bicycle chains in India, grew into a global powerhouse in bike chains and chain sprocket manufacturing.
From Bicycle Chains to Automotive Components
Rockman’s industries, earlier known as Rockman Cycles Ltd., started its journey in 1960 by manufacturing bicycle chains and hubs for cycles. But their ambitions didn’t stop there. In the late 1990s, leveraging a technology transfer from Izumi, Japan, they began manufacturing two-wheeler drive chains and cam chains—a move that marked their entry into the larger automotive world.
By 2005, they had exited the bicycle parts business, fully committing to die-cast components and auto-chains for OEM giants like Hero MotoCorp, TVS, Royal Enfield, Honda, and many more. This strategic shift set Rockman on a trajectory toward becoming one of India’s most trusted automobile component manufacturers—especially in the chain and sprocket space.
A Strong Foundation: Infrastructure and Capacity
Growth doesn’t happen overnight. Rockman built a solid infrastructure backbone:
- A dedicated plant in Mangli, Ludhiana, with a capacity to produce 60,000 meters of chains per day.
- One of India’s first in-house heat treatment and metallurgy labs, enabling precise control over hardness and wear resistance.
- Advanced Tool & Die workshops, including CNC milling, wire-cut EDM, grinding, jig-boring, are all crucial for making components like chain sprockets with micrometre accuracy.
- Full-fledged R&D labs equipped for endurance testing– including universal testing machines and twist and fatigue checks, ensuring parts meet international OEM standards.
With this kind of setup, Rockman wasn’t just manufacturing; they were innovating.
Product Range: Drive Chains, Cam Chains, Sprockets and More

Rockman’s chain lineup caters to a variety of needs:
- Drive Chains: (models like 420, 428, 428H, 520, and O‑ring variants) – powering the everyday performance of commuter bikes.
- Cam Chains: (25H, 25HS) – critical to engine timing, made in dust-free enclosures for zero-contamination assembly.
- Industrial Chains: used in machinery beyond vehicles—covering sizes like 08B, 10B, 12B, duplex/triplex, and various attachments.
- Sprockets: for all Royal Enfield models
They even offer OEM-grade quality chain and sprocket kits for popular motorcycles, such as the Honda Shine, ensuring aftermarket convenience.
The Rockman Quality Advantage
So what sets Rockman’s chains apart in a crowded market?
1. In-House Metallurgy & Heat Treatment
They use continuous hardening and tempering furnaces. Their case-carbo-nitriding process ensures chains have a hard, wear-resistant surface and a tough core—vital for chains withstanding shock and rough ground impact.
2. Precision Engineering for Sprockets
Their toolroom capabilities—like CNC, profile grinders, and EDM machines—enable sprockets with flawless tooth geometry and durability. Even specialised items like sprockets demonstrate Rockman’s attention to detail.
3. R&D and Lab Testing
With testing for endurance, fatigue, hardness, twist, and length, Rockman meets and surpasses OEM benchmarks. It’s a scientific approach that guarantees long-term performance.
4. Dust-Free Chain Production for OEM Integration
Producing cam chains in clean environments ensures they can be assembled directly in OEM lines without cleaning—streamlining production and reducing costs.
Making an Impact: OEMs, Aftermarket and Beyond
Rockman’s supplies to a wide variety of customers and channels:
- OEM Supply: Supplying major brands—Hero MotoCorp, TVS, Royal Enfield, Ather Energy, Honda, Kia, Ford, Mahindra, Tata, and international suppliers like Bosch, Continental, BorgWarner, Rockman, etc
- Aftermarket & Spare Parts: Under “Hero Rockman” banner, their chain kits for Shine, Pulsar, CBZ, and others offer reliable replacement parts Safex Bikes.
- Industrial Use: Their higher pitch chain range powers industrial machinery with the same quality standards.
This blend of OEM-grade and aftermarket products strengthens Rockman’s footprint across all chain sprocket needs.
Made in India, Delivered Globally
Rockman’s rise as an industry leader isn’t just a manufacturing success story; it’s a Made in India success. With manufacturing facilities based in eight major cities of Ludhiana, Haridwar, Bawal, Chennai, Surat, Vadodara, and Tirupati, Rockman is fully equipped to deliver to a global clientele.
An inspiration for the industry, their homogenised approach of Indian technical prowess, intelligent infrastructure, and global collaborations makes them invincible among their competitors. Beginning with bicycle parts, the brand also ventured into manufacturing modern automotive chains. Over the years, they’ve covered every vertical that needed to be exploited in this domain.
The Road Ahead: Innovation and Sustainability
Rockman isn’t resting on its laurels. They’re expanding:
- Into carbon composites and alloy wheel manufacturing—expanding their engineering edge.
- Building a strong aftermarket network, with 150+ pan-India partners and exports.
- Investing continuously in R&D, lean manufacturing, and environmental initiatives—reflecting their commitment to sustainable growth.
