Hydraulic Cylinder Barrel
Honed Tube Manufacturer & Supplier in China
Honed Tubes / Hydraulic Cylinder Tubes
Hydraulic Cylinder Tubes, often referred to as Honed Tubes, are essential for hydraulic cylinder applications as they require no further internal diameter machining. Honed tubes are highly regarded in various industries and are known for their precision and durability. These tubes undergo a meticulous degreasing or roller burnishing process, making them critical components in the manufacture of hydraulic cylinders. Due to the honing process on the inner diameter, these tubes are also called honed ID tubes.
- Da Tong, a leading supplier and manufacturer of Honed Tubes, provides high quality steel honed tubes and degreased roller polished tubes for pneumatic and hydraulic cylinder applications at highly competitive prices. We offer both metric and imperial sizes to meet the diverse needs of our customers.
- With nearly 16 years of industry experience, Da Tong has established itself as a reliable supplier of Honed Tubes for Hydraulic Cylinders. Please find below detailed information on our Honed Tube products.

Honed Tube Packaging
Honed tube packaging is essential to ensure that hydraulic cylinder tubes are well protected and secure during transport and storage. Proper packing protects the tubes from potential damage from impact, abrasion, moisture and dust, preserving their quality and extending their life.
Here are some common packing methods for hydraulic cylinder tubes
- Wooden crates: Tubes are placed in custom-designed wooden crates that match their size and shape to provide robust protection against shock and abrasion. The crate is securely fastened with screws or nails to maintain stability.
- Steel banding: Tubes are tightly wrapped in steel banding using a ratchet tool for secure fastening. This method provides additional protection from handling impacts and abrasions.
- Plastic Wrapping: Tubes are wrapped in a protective layer of plastic to protect them from moisture and dust. The plastic wrap is further reinforced with steel strapping or tape.
- Plastic bags: Each tube is placed in a large plastic bag, which is then sealed and secured with steel strapping or tape to provide a barrier against environmental elements.
- Prior to packing, each honed tube is carefully oiled to prevent rust and ensure that they remain in optimum condition throughout transit. The method of packing chosen will depend on the size and weight of the tube, the distance to be travelled and the specific requirements of the customer.
