Ø8mm Chrome Plated Linear Bearing Shaft - Cut To Length

Ø8mm CF53 Chrome Plated Induction Hardened Linear Bearing Shaft – KM-WV-8

Precision shaft for compact and light-duty linear motion in demanding environments

The KM-WV-8, 8mm chrome plated linear bearing shaft from Kiwi Motion is engineered for small to medium linear motion assemblies that demand both precision and durability.

With an 8mm diameter, a high-surface-hardness chrome plated finish, and excellent corrosion resistance, this shaft is ideal for automation systems exposed to moisture or washdown processes.

Manufactured from CF53 steel, the KM-WV-8 shaft is induction hardened to a minimum surface hardness of 62 HRC, providing exceptional wear life even under continuous cycling.

The addition of chrome plating enhances corrosion resistance, making this shaft suitable for harsh environments where traditional shafts would degrade rapidly.

Each shaft is precision ground to an h7 tolerance, with roundness held within 6 µm and straightness within 0.20 mm per metre, ensuring smooth, accurate linear motion with low friction.

Applications for the KM-WV-8 Linear Shaft

The 8 mm KM-WV-8 shaft is a popular choice for light-duty linear motion applications where a balance of corrosion resistance, precision, and compact size is required. Typical uses include:

• 3D printers and small CNC machines
• Router sleds and lightweight gantry systems
• Laboratory automation exposed to humidity or chemical agents
• Food processing and packaging equipment requiring frequent washdown
• Outdoor positioning and inspection devices

The chrome plated surface and high hardness ensure excellent performance over extended service life, even in conditions involving coolant spray or fluctuating humidity.

Custom Lengths and End Machining Options

Each 8mm chrome plated linear bearing shaft is cut to your exact specified length, with a precision tolerance of ±0.1 mm. This allows easy integration into both custom machinery and retrofit systems.

For applications requiring more complex designs, Kiwi Motion also offers custom end machining on request.

We can provide chamfers, threads, flats, or other end features to suit your specific assembly needs, helping reduce build time and machining effort.

Compatible with Kiwi Motion’s Bearings and Shaft Supports

The 8mm chrome plated linear bearing shaft is fully compatible with Kiwi Motion’s linear bearings and shaft supports, ensuring smooth integration and dependable system performance.

This compatibility allows you to build corrosion-resistant and durable linear motion systems that maintain precision across demanding environments.

For compact and light-duty linear motion with the added protection of chrome plating and superior surface hardness, the KM-WV-8 shaft is an excellent choice.
