Hard Chrome Linear Shaft
The Hard Chrome Linear Shaft is a precision guide shaft that has been processed with high precision and hard chrome plated on the surface. It has high hardness, high finish and excellent wear resistance. It is mainly used to provide linear motion support or sliding guide function, and is an indispensable key component in automation equipment, CNC machine tools, industrial robots, packaging and printing equipment and other fields.
Product advantages
High hardness
The surface of the hard chrome linear axis is heat treated and hard chrome plated, and the hardness usually reaches HRC58-62, and the typical value is HRC60±2. It is particularly suitable for linear motion systems with frequent sliding and heavy loads, such as automation equipment and CNC guide rails.
High finish
The surface of the shaft body is precision ground and mirror polished, and the roughness can be controlled at Ra≤0.2μm. Some models range from Ra≤0.2-0.4μm, which can effectively reduce sliding friction resistance, reduce noise and vibration, and improve the smoothness of bearing matching.
Strong anti-corrosion performance
The thickness of the chrome plating on the surface of the product is usually controlled at 0.01-0.10 mm (typical value 20~25μm). The chrome layer is dense, which can effectively block air and moisture, and has good anti-rust ability. It is suitable for industrial sites in humid environments or with light corrosive atmospheres.
Multiple processing capabilities
Before leaving the factory, the shaft can be processed at both ends according to customer needs, including chamfering, threading, drilling, grooving, etc., to adapt to different mechanical structure assembly requirements.
Multiple specifications cover a wide range
The standard diameter of the hard chrome linear shaft covers a range of 6 mm to 50 mm, and the length ranges from 50 mm to 6000 mm, which can meet the shaft length and space installation requirements of various equipment.

FAQ
Q: 1. Can both ends of the hard chrome linear shaft be precision machined according to the drawings?
A: Yes, we support precision end machining according to the drawings provided by customers, including key slots, flat milling, positioning holes, internal and external threads, etc., to meet specific installation structure requirements. We have a CNC machining center to ensure machining accuracy within ±0.01mm.
Q: 2. How to avoid bending or surface scratches on the linear shaft during transportation?
A: Each hard chrome shaft will be fully enclosed in a plastic tube or foam before shipment, and packed in a reinforced wooden box or steel frame packaging to prevent compression deformation or surface damage during transportation, ensuring that customers receive qualified finished products.
Q: 3. Do you provide material testing or quality reports?
A: We can provide material certification (such as the original material list of the steel mill), hardness test report, straightness test report and coating thickness report with the goods. If there are special requirements, we can also assist third-party organizations in SGS, RoHS and other certification tests.
Q: 4. Can the hard chrome shaft be used normally in a high temperature environment?
A: Hard chrome linear shafts are suitable for most normal or medium temperature applications (<120°C). If used in continuous high temperature conditions (such as above 150°C), it is recommended to use stainless steel and perform special heat treatment to prevent micro-cracks or peeling of the hard chrome layer due to thermal expansion.
Q: 5. If you purchase a custom length, how long will the delivery cycle take?
A: For conventional diameter models that need to be cut to a fixed length, the delivery time is usually 3-5 working days; if special end processing or large-scale customization is required, the cycle is generally 7-15 days. We have multiple processing lines and can flexibly adjust the production schedule according to the order quantity.
