Salt Spray Test

TPS Series Shaft Salt Spray Test Report

Corrosion Resistance Verification for Industrial Applications

The TPS Series Roller Linear Guide's steel shaft has undergone a 48-hour salt spray test to evaluate its corrosion resistance in demanding industrial environments. The test was conducted under controlled laboratory conditions using sodium chloride (NaCl) solutions with different plating thicknesses.

The results demonstrate that the TPS guide shaft maintains excellent corrosion resistance after testing, making it suitable for applications exposed to moisture, high humidity, and mildly corrosive environments.

Result :  ★★★★★  PASS 

Test Conditions

Test Standard : Salt Spray Test

Test Duration : 48 Hours

Test Solution : 5% NaCl  /  10% NaCl

Shaft Surface : Hard Chrome Plating

Plating Thickness : 0.01 mm / 0.02 mm

Result : PASS

After 48 hours of salt spray exposure:

No rust was observed on the shaft surface.

Only slight corrosion appeared on the end faces.

All four test samples met the acceptance criteria.

Why Salt Spray Testing Matters

Salt spray testing is widely used to evaluate the corrosion resistance of metal components operating in harsh environments.

For linear guide systems, corrosion resistance is especially important in applications such as:

• Automation equipment

• Food processing machinery

• Packaging equipment

• Humid production environments

• Electroplating equipment

• Semiconductor auxiliary equipment

The TPS Series is designed to provide reliable operation in environments where corrosion protection is an important consideration.

Note: The TPS  rollers are made of wear-resistant steel and are not electroplated, as the plating would quickly wear off during rolling contact.
