UNPARALLELED LTD is one of the leading manufacturers and suppliers of granite air‑bearing guide base in China. With abundant experience, we warmly welcome you to buy advanced granite air‑bearing guide base made in China here from our factory. We also accept custom orders.
Product Overview
UNPARALLELED Group granite air‑bearing guide base is a fixed guiding benchmark for air‑bearing motion systems. Made of fine‑grain black granite, it is processed through strict blank inspection, multi‑stage aging, ultra‑precision lapping and micro‑pore sealing, and supplied with CNAS and IAF calibration certificates.
Two types are available: straight type and L‑shape enclosed type. The guiding surfaces ensure full‑travel flatness and straightness. Pre‑embedded stainless steel inserts and locating pin holes are adopted. Light‑weight slots can be processed on the back. All corners and hole edges are chamfered to prevent chipping, suitable for clean‑room environment. Cooperating with air‑bearing sliders, it forms friction‑free air film to eliminate stick‑slip and mechanical wear. It is widely used in CMM, wafer inspection and AOI equipment. UNPARALLELED Group conducts full‑range inspection in constant‑temperature anti‑vibration workshop and supports gravity‑sag compensation to guarantee long‑term motion accuracy.

Main Application Fields
Coordinate Measuring Machines (CMM): Used as Y‑axis guide rail for bridge‑type CMM to ensure accuracy of long‑travel scanning measurement.
Semiconductor Wafer Inspection Equipment: For wafer appearance and dimension measurement, suitable for clean‑room environment to realize high‑speed stable scanning.
AOI Optical Inspection Equipment: Applied in PCB, display and optical‑component visual inspection for high‑speed reciprocating movement of camera modules.
Video Measuring Machines: Deliver jitter‑free and stick‑slip‑free linear motion for large‑travel video measuring systems.
Laser Micro‑machining Equipment: Laser cutting, marking and micro‑processing equipment to suppress motion vibration and secure machining accuracy.
Scientific Research Instruments: Interferometers and high‑precision scanning platforms for universities and research institutes.
Quality Assurance
UNPARALLELED Group implements a complete quality‑assurance system for granite air‑bearing guide bases. Strict incoming inspection is performed for raw materials to rule out cracks and impurity defects. Full‑process machining control is adopted. Key dimensions and geometric tolerances are tested by laser interferometer inside constant‑temperature anti‑vibration workshop.
CNAS and IAF calibration certificates are available for finished goods. Test records are kept for each component to realize full‑process traceability. Visual inspection, chamfer check and pre‑embedded insert fitting verification are carried out before delivery to avoid chipping and thread failures. One‑year warranty is offered. Export fumigated wooden cases with shock‑absorbing filling are applied to prevent transit damage. After‑sales technical support is also available.

Installation Notes
The mounting base shall keep good flatness. Lift by pre‑embedded inserts, never pry the guiding surface. Prevent impact on air‑bearing surface during assembly. Supply clean compressed air in operation. Regular cleaning for guiding surface is recommended.
Packaging & Delivery
UNPARALLELED Group uses fumigated export wooden cases with shock‑absorbing filling to prevent transit damage. Lead time depends on project requirements. Sea and air shipment are acceptable.
