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.
