Linear Shaft 8 mm Ø, Length 350 mm — OEM

OEM linear shaft with an 8 mm diameter and 350 mm length designed for linear motion systems and bearing assemblies. The shaft is precision-machined to provide a straight, hardened surface that supports smooth linear movement and accurate load guidance. It is compatible with linear bearings, shaft supports, and guide systems used in automation equipment, CNC machines, 3D printers, and various DIY mechanical projects.

Advantages

The shaft offers a consistent cylindrical profile and dimensional accuracy that reduce play and wobble in linear assemblies. Its hardened surface increases wear resistance and extends service life when used with matched linear bearings and supports. The standard 8 mm diameter and 350 mm length make it straightforward to replace or integrate into common guide systems without custom machining.

Suitable for

• Linear motion systems in automation and robotic equipment
• CNC machines and milling jigs requiring guided movement
• 3D printers and plotters as guide or support rods
• DIY projects and custom mechanical assemblies
• Replacement of worn guide shafts in bearing housings

Key specifications

• Diameter: 8 mm
• Length: 350 mm
• Material: precision-machined steel (hardened surface)
• Surface finish: ground cylindrical surface for smooth bearing contact
• Intended use: linear guide and bearing shaft

How to use

Measure the existing guide geometry to confirm the 8 mm diameter and 350 mm length fit your assembly. Slide the shaft through compatible linear bearings or supports, ensuring bearings are rated for the shaft diameter and the bearing housings are aligned to prevent binding. Secure the shaft ends with bearing supports, collars, or set screws as required by your mechanical design. Maintain correct alignment during installation and verify smooth movement before applying operational loads.

Usage recommendations

For reliable performance, pair the shaft with bearings specified for 8 mm shafts and ensure bearing housings are mounted on a rigid, well-aligned frame. Apply appropriate lubrication compatible with the bearing type and operating environment; inspect periodically for wear or corrosion, and replace the shaft if surface damage affects bearing contact.
