Stainless Steel Precision Bars
Applications
Piston Rods, Pump Shafts, Boat Shafts, Cylinder Shafts, Precision Machined Parts, Automotive Components & Others.
Superior Surface Finish, Diameter Tolerance & Straightness is achieved by additional processes, such as Straightening, Roller Burnishing and Centreless Grinding. Precision Bars are 100% inspected for diameter tolerance, out of roundness, surface roughness & straightness by specially designed instruments & gauges. Ultrasonic Inspection is done to ensure bars are free from internal defects. Bars are packed in strong plywood boxes with each bar protected with distance rings to avoid scratches.
