RFQ checklist
Roller diameter, tube length, shaft end, and installed position
Bearing model, bearing seat size, seal type, and end cap detail
Drawing, sample photo, worn part photo, or measured dimension sheet
Material, coating, surface finish, tolerance, and assembly requirement
Quantity by component, destination port, packing, and repeat demand
Material and fit notes
Roller component quotes depend on shaft machining, bearing seat tolerance, seal structure, shell material, surface treatment, and order quantity.
End caps, bearing seats, seals, shafts, and roller shells should be separated by item line when the RFQ includes multiple components.
A worn sample photo helps, but dimensions and bearing model are needed before reliable component matching.
Inspection points
Bearing seat diameter and fit tolerance
Shaft end, thread, groove, and chamfer measurement
Seal fit, end cap position, and assembly clearance
Surface finish, coating, runout, and burr review
Packing separation for mixed roller component shipments
Buyer questions
Practical answers before sending an RFQ.
Can roller components be quoted from a sample photo?
A sample photo helps identify the part, but roller diameter, shaft end, bearing model, seal detail, dimensions, and quantity are needed.
Are sealed bearing seats standard parts?
Some bearing seats can be matched by size, but many conveyor roller components require drawing-based or sample-based review.
Can components and complete rollers be sent in one RFQ?
Yes. Separate complete rollers from shells, shafts, bearing seats, end caps, and seals so each item can be reviewed correctly.
