Rectangular Frame Module with Roller Conveyor Module and Flanged Bearing Shafts

304 and 316 stainless are the two grades most specified for a roller conveyor module with flanged bearing shafts; 304 suits dry handling lines in semiconductor tool manufacturing, drone assembly conveyors, and robotics cell transfer modules where Ra 0.8 μm surface finish and standard corrosion resistance are sufficient, while 316 is required for roller conveyor module applications in wet food processing, boiler room, or shipbuilding environments where chloride exposure is a service condition. Roller shaft centre-to-centre spacing variation above ±0.5 mm creates gaps in the conveyor bed and allows small parts to drop between rollers. Hangzhou Pengbo Precision Machinery (Hangzhou, Zhejiang, established 2009, ISO 9001 certified) fabricates this rectangular frame roller conveyor module with flanged bearing shafts at their approximately 20,000 m² Hangzhou facility on CNC milling equipment, milling & turning, and boring & milling, with shaft spacing, roller face flatness, and frame squareness compared to your released dimensions at initial sample check. Pengbo serves semiconductor, robotics, machinery, shipbuilding, and boiler roller conveyor module applications. We can quote once we have shaft spacing tolerance, roller face flatness, frame squareness, and stainless grade from your drawing. And we will return an estimate from our hangzhou team, active in drones, fasteners, and photovoltaics.
