Ceramic Tube RFQ & Specification Checklist
For quotation, provide the latest drawing, service conditions, order quantity, critical characteristics and required inspection documents.
| Technical Item | Reference Capability | Engineering Notes |
|---|---|---|
| Product form | Fused-silica hollow roller | Final grade, dimensions and end interfaces are confirmed during drawing review. |
| Manufacturing route | Near-net shaping, high-temperature sintering and precision cold machining | The process route is selected according to geometry, tolerances and order quantity. |
| Maximum service temperature | Up to 1,200 °C for the referenced hollow-roller grade | Allowable temperature is verified against grade, load, atmosphere and continuous or peak duty cycle. |
| Surface finish | Ra 0.6–1.0 µm (reference range) | The required contact surface and measurement method must be stated on the drawing. |
| Radial runout | <0.10 mm (reference value) | Acceptance is defined against an agreed datum, diameter and working length. |
| Typical applications | Glass tempering and annealing, steel-strip annealing, float-glass transfer and large-format tile lines | Final suitability depends on equipment design and operating conditions. |

Ceramic Tubes & Hollow Rollers: Buyer Questions
Answers to common questions from engineering and purchasing teams.
Which materials are available for ceramic tubes and hollow rollers?
RYANCERA currently supplies fused silica and alumina components. Fused silica is commonly reviewed for low thermal expansion, while alumina is considered for wear, insulation and mechanical service.
Can you manufacture central bores and multiple auxiliary bores?
Yes, multi-bore and custom end geometries can be reviewed from a complete drawing. Bore diameter, position, wall section, end details and inspection method must be defined.
How should wall thickness, bore pattern and straightness be specified?
Use a dimensioned drawing with datums, tolerances and critical characteristics. State whether straightness or runout applies and define the working length and measurement method.
What temperature can a ceramic tube or hollow roller withstand?
Temperature capability depends on the exact material grade, load, atmosphere, support arrangement and duty cycle. Any published reference value must be verified for the actual application before quotation.
Can prototypes and repeat-production batches be supplied?
Prototype and repeat-production requirements are reviewed separately because tooling, process control, order quantity and inspection planning may differ.
What inspection records can be supplied?
Available records may include agreed dimensional, straightness, runout, visual, material and batch documents. State the required reports and acceptance criteria in the RFQ.
