NRB Bearings Limited

NRB makes needle roller bearings, cylindrical roller bearings and precision components. It was the first company to make needle bearings in India, in 1965, and still holds roughly 60 percent of that segment here. More than 90 percent of vehicles on Indian roads run on an NRB part. The catalogue runs to about 4,000 products, sold into more than 40 countries.

Customers bring a design problem and NRB engineers a part around it. That is why the same company sits inside BMW transmissions from the 1 Series to the 7 Series, Mercedes from the A class to the Maybach, heavy defence equipment supplied through Meritor, Siemens drives and JCB's off-highway machines. The technical base is material science, sealing, lubrication and friction, plus in-house simulation software.

The group is deliberately kept as small units rather than one block. SNL Bearings at Ranchi is a separately listed subsidiary that NRB controls, with its own brand at a lower price point, aimed at the price-sensitive replacement market. NRB USA runs a new plant at Columbia, South Carolina. Mahant Tool Room, acquired this year, is the aerospace and defence arm. A joint venture with Unitec is being built at Shendra near Aurangabad for large industrial cylindrical roller bearings.

For most of the last decade NRB was one story: needle bearings into Indian automotive, revenue compounding in single digits, and a promoter family that had pledged most of its stake. Both of those facts changed inside the same twelve months.

The pledge is effectively gone. In April 2026 close to 38 percent of the equity capital sat encumbered against promoter borrowings. The family sold about 6.5 percent of the company, repaid the loans in steps through May, June and August, and encumbrance is now down to roughly 5.5 percent. Foreign and domestic institutions bought the block. That removes the single biggest reason a quality engineering franchise was left alone by institutional money.

The second change is what the company sells and to whom. NRB spent a decade building capability without new end markets to sell it into. It now has four, and each has a customer name against it rather than a plan. The US plant has its first production order. The aerospace arm was bought already certified, so it skipped the multi-year approval wait. Industrial has moved from 11 percent of revenue to 14 percent and grew 34 percent last year. The Aurangabad joint venture has land, a partly built shed and a commissioning date. None of it needs a new capability, only capacity that is already ordered filled by customers who have already signed.

The US plant turns on. NRB has won a production order for high-precision planet pins for the General Motors Corvette programme, through a tier-one transmission maker that is already a customer. The programme is closed to anyone not manufacturing in the United States, which is exactly why the plant exists. Peak volume is 300,000 units. This one win took lifetime nominated business from Rs 800 cr to Rs 1,100 cr.

Unitec joint venture, April 2027. Rs 110 cr going in, and the plant supports about Rs 130 cr of sales. The location moved from Hyderabad to Aurangabad, where NRB already has people, suppliers and a partly ready building it has purchased. The product is industrial cylindrical roller bearings for large gearboxes, which is a different customer set from autos.

Aerospace and defence. Mahant Tool Room brings roughly Rs 30 cr of orders in hand, with another Rs 20 cr sitting in NRB's regular defence work. The breakthrough item is a plain spherical bearing for the Sukhoi-30, a part fewer than five companies in the world can make. Management projects Rs 300 cr of revenue and Rs 90 cr of profit contribution from this vertical by 2031. That is their number, not mine, and it is not in my estimates.

Industrial mix. Management wants industrial at 20 to 25 percent of revenue against 14 percent today. Industrial carries better pricing than automotive, so the mix shift is a margin lever independent of volume.

Capex already committed. Rs 270 cr sanctioned, Rs 60 cr spent, another Rs 100 cr ordered or being ordered. Management's own conversion rate is Rs 100 cr of capex producing Rs 130 cr of annual sales, which puts about Rs 350 cr of incremental revenue capacity in the ground by FY29.

Early-stage optionality. Robotics, data centre cooling bearings and industrial electrification are in development with no revenue attached yet. Worth watching, not worth paying for.

Q1 holds as a seasonal share of the year at roughly 23 percent, which is what FY26 did, giving FY27 revenue near Rs 1,570 cr. Growth then tapers to the mid-teens as the new plants fill. Operating margin moves from 17.4 percent to 18.5 percent on industrial mix, not on any assumed cost saving. Depreciation rises with the capex, interest stays near current levels, tax at 26 percent, and no dilution on 9.69 cr shares. PAT is after minority interest.

Gross debt was Rs 154 cr at March 2026, down from Rs 187 cr, or about 0.6 times EBITDA. Cash generation covers the capex programme without leverage.

At Rs 447 the price only asks NRB to fill capacity it has already paid for, at customers who have already nominated the parts. On these numbers earnings compound at about 15 percent a year and the multiple falls to under 20 times FY29 on the base business alone. Aerospace is not in the table at all. Neither is the Corvette ramp beyond its first year, nor anything from robotics or data centres. Each of those shifts the mix towards higher-margin, longer-contract work, which is what changes the multiple the market is willing to pay for the whole company rather than simply adding a line of revenue.

Cost inflation is live. Other expenses jumped about Rs 10 cr in Q1 on electricity, logistics and petroleum-linked inputs. Consolidated operating margin was 17 percent against 18 percent in the March quarter. Price increases and value engineering both lag the cost.

Consolidated profit grew 15 percent in Q1 while standalone profit grew 32 percent. The subsidiaries are diluting the parent. The US plant and the aerospace arm are in their early, barely profitable phase, so the gap is the price of the pivot, but it persists until those units scale.

Working capital is heavy. Inventory is about 300 days and the cash conversion cycle 281 days, improved from 338 but still consuming cash as the company grows.

Industrial is 14 percent of revenue. Almost all of the rest is automotive, so a domestic auto downcycle lands before any new vertical is large enough to cushion it.

Aerospace revenue timing depends on whether HAL or an airframer wins the underlying order, which NRB does not control. Management gives the full picture once a year and declines quarterly guidance.

Operating margin below 16 percent for two straight quarters with no input cost explanation. Unitec commissioning slipping past April 2027. Industrial stuck at 14 percent of revenue a year from now. Cash conversion cycle back above 320 days. Any fresh promoter pledging.
