Honed Tube Supplier Guide for Hydraulic Cylinder Buyers
Honed Tube
Honed Tube is used as the cylinder barrel in hydraulic and pneumatic systems. Because the piston seal works directly against the inner surface, the tube's dimensional tolerance, straightness, surface roughness, and inner bore quality have a direct effect on cylinder performance and service life.
For B2B buyers, selecting a Honed Tube Supplier is not only about finding a low price. A useful quotation needs material grade, inner diameter, outer diameter, length, tolerance, surface roughness, processing method, packaging method, quantity, and delivery requirement. These details help the supplier check stock, production feasibility, and inspection requirements.
JINYO supplies honed tube for hydraulic cylinders, pneumatic cylinders, and construction machinery. The listed material options include C20, E355 / ST52, SAE1026, 4140, STKM13C, and stainless steel 304 / 316. Processing options include honed and Srb Tube, with BK and BK+S surface conditions listed in the product parameters.
When comparing suppliers, buyers should pay special attention to the inner diameter tolerance and surface finish. JINYO lists H8 to H9 tolerance and Ra0.4 um surface roughness for honed tube. For cylinder manufacturers, these parameters are important because they affect sealing performance, friction, oil retention, and assembly consistency.

Applications
Honed tube is commonly used in hydraulic cylinders, pneumatic cylinders, and construction machinery cylinders. It is suitable for equipment where the cylinder barrel must support smooth piston movement, seal stability, and reliable pressure performance.
Buying Tips / Supplier Selection Checklist
- Confirm both ID and OD. Cylinder barrel selection depends on the bore size, wall thickness, and machining allowance.
- Ask for the tolerance and roughness requirement in the inquiry. H8 to H9 tolerance and Ra0.4 um surface roughness are listed in the JINYO product file.
- Specify material grade clearly. C20, E355 / ST52, SAE1026, 4140, STKM13C, and stainless steel 304 / 316 may serve different cylinder requirements.
- Check packaging before export shipment. Anti-rust oil, end caps, waterproof wrapping, markings, and wooden crates help protect the inner bore during transport.
- Share drawings when the tube is for a custom hydraulic cylinder project. Drawings reduce back-and-forth communication and help the supplier confirm feasibility faster.
