Hardev Hydraulics manufactures involute spline rolling machines, straight spline rolling machines and PTO spline rollers for automotive, agricultural and industrial shaft applications. DIN 5480, SAE J498 and ISO 4156 standards supported.
A spline rolling machine cold-forms involute or straight splines on cylindrical shafts using hardened die rolls. The rolling process cold-works the shaft surface, producing splines with superior fatigue strength, dimensional accuracy and surface finish compared to hobbing, milling or broaching.
Spline rolling is the preferred method for high-volume automotive driveshaft splines, PTO shafts and gearbox input shafts — where consistent quality and high production speed are essential. Hardev Hydraulics manufactures spline rolling machines in Ludhiana, Punjab for customers across India.

DIN 5480, SAE J498, ISO 4156 pressure angle splines for automotive gearboxes, driveshafts, power transmission.
DIN 5461 parallel-sided splines for agricultural machinery, industrial shafts and heavy-duty torque transmission.
6-spline and 21-spline PTO shaft profiles per ASABE standards for tractor and agricultural PTO systems.
Cold rolling work-hardens the spline surface, producing splines with 20–30% higher fatigue and torque capacity than hobbed splines.
Rolled spline flanks achieve Ra 0.4–0.8 µm — significantly smoother than hobbed splines — reducing fretting corrosion and improving fit quality.
Spline rolling displaces metal — no chips or coolant waste. Lower material cost and cleaner production environment.
10–40 splined shafts per minute — significantly faster than hobbing for the same shaft, reducing per-piece cost in volume production.
Hydraulic closed-loop control maintains spline module, pressure angle and pitch accuracy to DIN Class 6 or better consistently.
Hardened spline rolling dies last 50,000–200,000 shafts between regrounds, giving lower tooling cost vs hob replacement.
CV joint shafts, driveshaft splines, gearbox input shaft splines for Indian OEMs and Tier-1 suppliers.
PTO shaft splines for tractors, rotavators and farm implements — a major market in Punjab, Haryana, UP.
Gearbox shaft splines for industrial reducers, pumps and power transmission equipment.
Spindle splines for CNC and conventional machine tool manufacturers across India.
