Chrome Plated Machinable Guide Shaft

The Chrome Plated Machinable Guide Shaft combines a hardened main section with softened ends for mounting features such as threads, tapped holes and reduced-diameter steps. Its chrome-plated exterior and machinable end zones serve different purposes within a custom mechanical assembly.

Description

A finished shaft body with room for end machining

The main diameter of a shaft may fit a machine, yet its ends still need a thread, shoulder or fixing hole before installation. This product addresses that difference by combining a hardened working section with softer material at the two ends.

The listed construction provides approximately 2 inches, or 50.8 mm, of softened material at each end. These zones make local turning, drilling and threading more practical than machining the hardened section. They are intended for connection details, while the central section retains the specified working diameter.

A reduced end can locate a mounting component against a shoulder. An external thread can accept a retaining nut, while an axial tapped hole provides a fixing point through the end face. Radial holes serve a different connection direction. Each feature changes how the shaft fits the surrounding assembly, rather than simply changing its overall length.

Chrome plating and hardening are separate specifications

The Chrome Plated Machinable Guide Shaft is listed in GCr15 bearing steel with a chrome-plated surface. The steel grade identifies the substrate; the plating describes the exterior coating. Neither description alone establishes the finished shaft's hardness, diameter tolerance or surface roughness.

The hardened main section and softened ends must also be distinguished from the coating. Removing material to produce a thread or step can remove the existing plated surface in that area. Consequently, a machined end should not automatically be described as having the same surface protection as the untouched shaft body.

Item	Product specification
Base material	GCr15 bearing steel
Surface	Chrome plated
Listed diameters	3, 4, 5, 6, 8, 10, 12, 13, 16, 20, 25, 30, 35, 40, 50, 60, 80, 100, 120 and 150 mm
Overall length	Cut to the specified requirement
Treatment arrangement	Hardened main section with approximately 50.8 mm softened at each end
End-feature options	External threads, axial or radial tapped holes, and reduced-diameter sections

The softened-zone length describes the treatment arrangement, not an unrestricted machining allowance. A deep axial hole or long reduced section may extend beyond that zone, so the feature depth and treatment boundary need to be considered together.

Intended for support and custom mechanical connections

This Chrome Plated Machinable Guide Shaft is positioned primarily for support duties, rotating mechanisms and drawing-specific assemblies. A bright, smooth-looking surface does not by itself establish suitability as a direct rolling track for a linear ball bearing.

For that use, the bearing and shaft must have compatible requirements for hardness, finish and dimensional fit. The product's appearance and material name cannot substitute for those specifications. Keeping this distinction clear prevents a machinable support shaft from being treated as an interchangeable replacement for every hardened linear-bearing shaft.

About Us

Lishui Guangyuan Industry & Trade Co., Ltd. supplies linear shafts and related motion components, with cutting and machining services for drawing-based requirements.

For this shaft, available work includes CNC turning, drilling, tapping, milling and grinding. We accept OEM/ODM enquiries for specified lengths and end configurations, with a minimum order quantity of 10 shafts. The finished drawing is used to define the mounting features and any additional surface-treatment requirements.
