GB/T 97.1 is the standard cited for gl-xlc rotating shaft. This page sets out what the standard controls for this part, reproduces the dimensional table supplied against it, and notes the related designations referenced on drawings.
GB/T 97.1 — Scope
GB/T 97.1 is "Plain washers — Normal series — Product grade A". GB/T 97 1 is the Chinese national adoption of the same document.
Tolerance & Product Grades
GB/T 97.1 is written to product grade A; a different grade of the same part is a different document in the family, not a variant of this one.

Companion Standards
GB/T 97.1 controls the geometry of gl-xlc rotating shaft — gb/t 97.1 / iso 7089 (series 085). Surface finish is governed by separate finish standards such as ISO 4042 for electroplating, and corrosion testing by ISO 9227 (neutral salt spray). Mechanical performance is set by the documents specific to this part family — ISO 898-1 and ISO 898-2 apply to bolts, screws, studs and nuts, and not here.
When to Specify GB/T 97.1
Choose GB/T 97.1 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for gl-xlc rotating shaft — gb/t 97.1 / iso 7089 (series 085).
Custom manufacturing · Made to drawing
Need a machined component to this standard in a non-standard size?
Parts built to GB T 97 1 are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down. Made by warm forging or thread turning.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
