Consistent Performance Under Real Operating Conditions

In industrial engineering, precision is not about meeting a tolerance once — it is about holding that tolerance batch after batch, shift after shift. A bearing housing machined 5 microns off-centre causes vibration. A separator roller with poor surface finish causes yarn defects. A gearbox shaft with a worn journal causes premature bearing failure. The consequences of imprecision are always larger than the part itself.

At InStock International, we manufacture and supply precision mechanical components specifically for high-speed, high-load, and continuous-duty applications across the Textile, Glass, Gearbox, and Automation sectors.

Our manufacturing processes — backed by Om Precision Engineering (Amba Group, since 1979) — are engineered to provide strict control over balance, surface finish, and dimensional accuracy. Every critical component is individually inspected before dispatch using our in-house quality infrastructure: Carl Zeiss CMM, Swiss-made digital height gauges, hardness testers, and metallurgical analysis capability.

What We Support

We support demanding industrial environments with precision-engineered components built for accuracy, stability, and consistent mechanical performance.

Precision Shafts & Rollers

High-precision shafts and rollers engineered for smooth, stable, and high-speed rotational performance in automated textile and industrial systems. Ground to h5/h6 shaft tolerances, with surface finish Ra ≤ 0.4 µm on all critical contact areas. Applications include separator rollers, main drive shafts, godet shafts, and guide roller assemblies for Barmag, Lohia, SML, and Numag machine configurations.

Rotating Components

Specialised rotating parts designed with a focus on dynamic balance, alignment accuracy, and vibration control for 24/7 industrial operations. Includes spindle and jockey pulley bearings, separator roller bearing units, twin-disc bearing assemblies, bobbin chuck shaft bearings, pressure roller bearings, and opening roller assemblies — for POY, DTY, FDY, and OE spinning machines.

Custom Machined Mechanical Parts

High-tolerance CNC-machined components manufactured strictly according to your technical drawings and OEM performance requirements — for any application where standard catalogue parts are unavailable. Covers IS machine variable equipment, gearbox housings and bearing seats, precision flanges, cycloidal gearbox eccentric elements, custom shafts, and KUKA robotic arm mechanical components.

Export-Quality Manufacturing Mindset

Structured quality systems and meticulous documentation control ensuring consistent batch standards for global dispatch. Every order includes dimensional inspection reports, material traceability, and surface quality verification — aligned with international import requirements across Europe, South Korea, South Africa, and the Americas.

Frequently Asked Questions

Find quick answers to common questions about our precision manufacturing capabilities, quality systems, component specifications, and long-term supply approach.

Yes — this is our standard process. Share your 2D drawings (DXF, PDF) or 3D CAD files (STEP, IGES), and our engineering team will review for manufacturability, confirm material and process specification, and provide a full quotation with lead time. First-article samples are produced and approved before batch production begins.

Our precision components serve five primary industrial sectors: Textile machinery (POY, DTY, FDY, OE spinning), Glass manufacturing (IS machine, hollowware, container glass), Gearbox and power transmission, Robotics and automation (KUKA KR series), and general industrial CNC machining. Each sector has distinct precision requirements — and we understand all of them.

Yes. Textile machine spindle bearings operating at 6,000–25,000 RPM are among the most demanding rotating components in industrial manufacturing. Our experience in dynamic balance, surface finish control, and precision fits makes us well-suited for any high-speed or high-load application where dimensional deviation directly impacts performance.

We utilize controlled heat treatment, precision grinding, and rigorous quality inspection—including balance testing and surface verification—to align with international standards.Our quality framework covers: incoming raw material verification with material certificates, in-process dimensional checks at each critical production stage, final inspection using Carl Zeiss CMM and surface measurement equipment, hardness testing for heat-treated components, and complete documentation issued with every batch. Inspection reports and dimension verification sheets are standard for all export orders.
