Ball Screw Supplier in India for CNC Machines
A ball screw turns rotation into straight-line motion with recirculating steel balls between a threaded shaft and a nut, giving low friction and very little backlash. TriQuench India supplies ball screws with nut in 16, 20, 25 and 32 mm diameters with 5 and 10 mm leads, including R16-5 (the 1605 size), SFU 2005, 2505, 2510, 3210 and R20-10 (the 2010 size).

Ball screw with nut: what to check before you buy
As a ball screw supplier in India, TriQuench India stocks ball screws and ball nuts for CNC routers, machining centres, laser and plasma machines. Each ball screw with nut is specified by diameter, lead, length, accuracy grade and nut type. A ground ball screw is precision-ground after hardening and is used where positioning accuracy is critical; a rolled ball screw is formed by rolling, costs less and suits most routers. The ball screw 2010 size (20 mm, 10 mm lead) suits faster axes; 5 mm leads give more force and finer resolution.
Ball screw price
Ball screw price depends on diameter, lead, length, accuracy grade (rolled or ground), nut type and end machining. Send the size, length and end-machining drawing, or the old screw, and we quote the screw, nut, BK/BF supports and coupling together.
Ball screw vs rack and pinion
| Factor | Ball screw | Rack and pinion |
|---|---|---|
| Best travel length | Short to medium axes (screw whip limits long, fast screws) | Long axes; racks are joined end to end |
| Accuracy and backlash | Very low backlash with a preloaded nut | Some backlash; reduced with helical racks and split pinions |
| Speed | Limited by screw length and critical speed | High travel speed on long axes |
| Thrust | High thrust, good for cutting forces | Depends on module and pinion size |
| Typical use | Z axis, VMC axes, short router axes | X and Y on large routers, laser and plasma tables |
Ball Screw: frequently asked questions
How do I select a ball screw for a CNC machine?
Start from the axis: travel length sets screw length, cutting and acceleration loads set diameter and nut, and the required speed and resolution set the lead. Use a 5 mm lead for force and fine resolution, 10 mm for speed. Check critical speed for long screws, then pick rolled or ground accuracy and matching BK/BF supports.
Ball screw vs rack and pinion?
Use a ball screw for short to medium axes that need high accuracy and low backlash, such as Z axes and VMC axes. Use rack and pinion for long axes on large routers, laser and plasma tables, where a long screw would whip or limit speed. Many CNC routers use racks on X and Y and a ball screw on Z.

How to Choose the Right Precision Ball Screws: 5-Step Engineering Guide
Step-by-step sizing and technical selection criteria recommended by machine design engineers for optimal cutting speed, rigidity, and lifespan.
Determine Axis Length & Critical Speed (RPM)
Longer axis screws vibrate if spun near their natural resonant frequency. Calculate critical whipping speed based on shaft diameter, unsupported length, and bearing end-support type.
Select Screw Lead (Pitch) Based on Speed Requirements
Use 5mm lead for high-thrust Z-axis vertical lifting with mechanical self-locking resistance, or 10mm–20mm lead for high rapid traverse velocities on X/Y axes.
Choose Single Nut vs Preloaded Double Nut
Single nuts have microscopic axial clearance (0.01–0.03mm). Double nuts feature internal spring or shim preloads that eliminate backlash completely during directional reversals.
Match Accuracy Grade (C7 vs C5 vs C3)
C7 rolled screws (0.05mm/300mm error) suit standard wood routers; C5 ground screws (0.018mm/300mm) and C3 ground screws (0.008mm/300mm) are essential for metal machining centers.
Verify Lubrication & Wiper Seal Protection
Ensure the ball nut incorporates double-lip synthetic rubber wipers to block metal chips and is connected to an automated ISO VG 68 slideway oil lubrication system.

| Ambient Temperature Handling | Thermal expansion causes 12 µm/m growth per 1°C temperature rise | Maintains temperature within 0.5°C of machine casting to avoid lead error |
| Operating Noise Level | < 65 dB smooth rolling contact with plastic circulation deflectors | < 60 dB quiet operation with ceramic recirculating balls |
| Duty Cycle Capability | Continuous duty when properly lubricated with ISO VG68 oil | 24/7 continuous high-acceleration cycle without thermal drift |
| Maintenance & Plumbing | Automatic grease/oil replenishment every 8 operating hours | Cooling fluid loop inspection plus rotary union seal replacement |
| Best Machining Applications | CNC router axes, engraving machines, plasma cutters, and pick-and-place | Ultra-precision VMC/HMC axes, jig boring, and aerospace mold milling |
Frequently Asked Questions — Precision Ball Screws
Answers to real user queries on prices in India, field diagnostics, repair procedures, VFD compatibility, and bearing maintenance.
What is the price of a CNC ball screw assembly in India?
In India, standard C7 rolled ball screws range from ₹3,800 to ₹8,500 per meter depending on diameter (Ø16mm–Ø25mm); preloaded C5 ground double-nut assemblies range from ₹8,500 to ₹22,000 per meter.
What is the difference between a ball screw and a lead screw?
A ball screw uses spherical steel bearings recirculating between the screw thread and nut, achieving over 90% mechanical efficiency with near-zero friction. A lead screw relies on sliding contact with 30–50% efficiency, generating friction, heat, and rapid backlash.
How do you eliminate backlash in a CNC ball screw?
Backlash is eliminated by using preloaded double ball nuts (DFU series) separated by a precision spacer washer, or by installing oversized bearing balls (angular contact preloading) inside the nut raceway.
How to repair a noisy or loose CNC ball screw assembly?
Repair involves removing the screw, inspecting raceways for pitting or brinelling, cleaning out old grease, re-balling with micrometer-graded precision chrome steel or ceramic balls, and straightening bent shafts on a hydraulic bench.
What lubrication should be used on CNC ball screws?
Use lithium-soap based NLGI Grade 2 grease for manual grease guns, or ISO VG 68 / ISO VG 100 slideway oil for automated centralized CNC lubrication pumping systems.
How often should ball screw support bearings be replaced?
Support bearings (angular contact thrust pairs like 7000 or 7200 series in BK/FK blocks) should be inspected every 5,000 hours and replaced immediately if axial play exceeds 0.005 mm.
What causes ball screw whipping at high speed?
Whipping occurs when screw rotational speed approaches its natural harmonic frequency. It is resolved by increasing screw diameter, reducing axis speed, or switching from fixed-supported to fixed-fixed bearing arrangements.
What is the difference between rolled and ground ball screws?
Rolled screws are formed by cold-extruding blank rods between rotating dies (C7 grade, ±50 µm/300mm error); ground screws are precision-cut on CNC thread grinding machines (C5/C3 grade, ±8 to 18 µm/300mm error) for high precision.
