By using automatic double end boring machine, roller pipe can be treated coaxially to make sure perfect fit with bearing house.-Bearing House Welding:Two bearing houses are pressed into the pipe, and welded together with the pipe.-Painting & Surface Treatment:Electrostatic painting, or customized painting demands.-Shaft Cutting:The shafts are cut into fixed length.-Flat Milling:The shaft is treated at two ends, making into the flat ends.-Final Assembling:The pipe and the shaft are press-fitted together with bearing, seal, seal cover, circlip, making into a steel tube conveyor roller with the automatic press assembling machine.Why Choose UsPackagingConveyor rollers are packed with plastic cloth, or plywood box or as per your specific requirements.FAQQ: How long warranty for goods ?A: All of our products have one year warranty.Q: What is your minimum order quantity?A: The MOQ is 50pcs, ans we can accept trial order to check the conveyor roller quality.Q:Can you provide a few free sample?A: Yes, we can provide sample sample as your need.Q: What are the payment terms of your company?A: T/T, L/C.
