T 5783 is the international standard for cylinder connecting sleeve — gb/t 5783 / iso 4017 (series 013). This page sets out what the standard governs, the size range it specifies, and the related standards you will see referenced in datasheets.
T 5783 — Scope
T 5783 specifies the dimensions and tolerances of cylinder connecting sleeve — gb/t 5783 / iso 4017 (series 013). Material, property class, surface finish and packaging are governed by separate documents in the same standards family (for example ISO 898-1 for the mechanical property classes of bolts and screws).
Tolerance & Product Grades
T 5783, alongside the related GB/T 5783 / ISO 4017 entries on this site, specifies product grades (typically A or B for fine work and C for general engineering) and tolerance classes for the controlling dimensions. Choose the grade against the precision your application requires.
Dimensions Specified by T 5783
| Size designation | Outer diameter / width (mm) | Length / height (mm) | Bore / thread (mm) | Material | Reference standard |
|---|---|---|---|---|---|
| Size 1 | 10 | 20 | 6 | C45 carbon steel | GB/T 1804-m |
| Size 2 | 12 | 25 | 8 | C45 carbon steel | GB/T 1804-m |
| Size 3 | 16 | 32 | 10 | C45 carbon steel | GB/T 1804-m |
| Size 4 | 20 | 40 | 12 | C45 carbon steel | GB/T 1804-m |
| Size 5 | 25 | 50 | 16 | C45 carbon steel | GB/T 1804-m |
| Size 6 | 32 | 63 | 20 | C45 carbon steel | GB/T 1804-m |
| Size 7 | 40 | 80 | 25 | C45 carbon steel | GB/T 1804-m |

Companion Standards
T 5783 controls only the geometry of cylinder connecting sleeve — gb/t 5783 / iso 4017 (series 013). The mechanical strength is set by ISO 898-1 (bolts and screws) or ISO 898-2 (nuts); the surface finish is governed by separate finish standards (e.g. ISO 4042 for electroplating). For corrosion testing, the relevant document is ISO 9227 (neutral salt spray).
When to Specify T 5783
Choose T 5783 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for cylinder connecting sleeve — gb/t 5783 / iso 4017 (series 013).
