manufacturer of precision SUB-MM & THZ dowel pins,face driver drive pins, needle roller pins! supplier of 6G waveguides (WR03, WR04, WR05), silicon nitride(G0,G1, G2)cylindrical rollers !

We are a specialized manufacturer of high-precision components and assemblies, dedicated to pushing the boundaries of machining accuracy, material science, and application engineering. With decades of accumulated expertise in ultra-hard materials and micro‑machining, we serve industries ranging from semiconductor equipment and aerospace to next‑generation telecommunications.

Ceramic Bearing Elements – Unmatched Accuracy

Our flagship product line includes ceramic silicon nitride (Si₃N₄) cylindrical rollers for high‑performance bearings. While most suppliers struggle to achieve consistent dimensional tolerances, we have mastered the production of rollers that meet G0 precision grade – the highest class defined by international bearing standards. G0 represents sub‑micron roundness, surface finish, and diameter uniformity, which directly translates into reduced vibration, lower heat generation, and dramatically extended service life under extreme speeds and loads. To our knowledge, only a handful of facilities worldwide can routinely deliver such accuracy in ceramic rolling elements, and we are proud to be among them. This capability is the result of proprietary grinding and lapping processes, combined with rigorous 100% inspection using laser interferometry and air‑gauging systems.

Readily Available Stock – Needles and Pins

Beyond ceramic rollers, we maintain substantial inventory of precision needles and dowel pins in a wide range of diameters, lengths, and materials – including bearing steel, stainless steel, and engineered alloys. Our stock program ensures same‑day or next‑day dispatch for standard sizes, eliminating long lead times that often plague the supply chain. We welcome enquiries for both standard catalogue items and custom specifications; our responsive sales team provides competitive quotes within hours

Ceramic Structural Parts for Semiconductor Manufacturing

Our silicon nitride and alumina ceramics are not limited to bearings. We fabricate complex structural components specifically designed for chip production equipment – including electrostatic chucks, guide rails, lift pins, and furnace tubes. These parts exhibit exceptional thermal shock resistance, chemical inertness, and dimensional stability at elevated temperatures, making them ideal for CVD, PVD, etching, and lithography modules. With surface finishes below Ra 0.05 μm and tight parallelism/flatness controls, our ceramic structures contribute directly to higher wafer yields and lower cost‑of‑ownership for fabs.

Pioneering 6G Millimetre‑Wave and Terahertz Hardware

In the realm of advanced communications, we have developed a specialised division for 6G‑ready precision CNC‑machined waveguides and cavities. Using dedicated multi‑axis milling and EDM techniques, we produce millimetre‑wave (mmWave) and sub‑millimetre waveguides for bands up to 300 GHz, as well as terahertz (THz) resonant cavities for frequencies exceeding 500 GHz. These components demand surface roughness below 0.2 μm Ra, angular tolerances within ±0.005°, and feature sizes as fine as 50 μm – all of which we consistently achieve.

Whether you require ultra‑precise ceramic rollers, off‑the‑shelf pins, semiconductor‑grade structural ceramics, or cutting‑edge 6G waveguide components, we are your trusted partner.
