Manufacturer, Supplier & Exporter of Precision Round Bar
Riddhi Siddhi Impex is a leading manufacturer and supplier of high-quality Precision Round Bars, engineered to deliver exceptional accuracy, uniformity, and dimensional stability for demanding industrial applications. These bars are produced using advanced cold-finishing, centerless grinding, polishing, and straightening techniques, ensuring extremely close tolerances that meet global quality standards. Our Precision Round Bars are used where flawless surface finish, tight dimensional accuracy, and high concentricity are essential for smooth mechanical performance...
We manufacture Precision Round Bars using a wide range of materials including carbon steel, alloy steel, stainless steel, tool steel, and custom grades depending on the application. Precision ground bars are processed through multiple finishing operations, including turning, centerless grinding, peeling, honing, and polishing to achieve tolerances as fine as h6, h7, h8, g6, or custom tolerances. These bars are ideal for high-speed rotating components, bearings, shafts, linear motion guides, spindles, and hydraulic/pneumatic systems..
One of the major advantages of our Precision Round Bars is the uniform surface finish, typically ranging from Ra 0.2 to Ra 0.8, ensuring minimal friction during machine operations. Such precision finishing makes them suitable for CNC machining, automotive components, textile machinery, printing machines, pumps, compressors, and high-performance industrial equipment. The bars are straightened to micro-level accuracy, resulting in enhanced operational stability and trouble-free installation.
Riddhi Siddhi Impex’s Precision Round Bars undergo stringent mechanical and metallurgical testing, including hardness testing, tensile testing, microstructure analysis, straightness checking, ultrasonic testing, and surface defect inspection. This ensures each bar meets strict tolerance requirements and delivers long service life even in high-load, high-speed applications. We also provide material traceability, heat treatment verification, and complete Mill Test Certificates (MTC) as per EN 10204 standards..
We supply Precision Round Bars in a variety of diameters ranging from 4 mm to 120 mm, and custom sizes can be manufactured based on project requirements. Precision bars are supplied in cut-to-length pieces or full-length bars (1000 mm to 6000 mm). Our in-house machining capabilities allow us to deliver additional processes such as chamfering, threading, drilling, turning, and custom profile machining on request..
