Specification
Brand : Slocable
BulletPoint1 : HIGH PRECISION: With high-precision dimensional tolerance and geometric tolerance, it is widely used in various precision equipment, so you can use it with confidence.
BulletPoint2 : GOOD MATERIAL: Bearing steel with excellent wear resistance (equivalent to SUJ2 and SUS440C) or equivalent high hardness corrosion-resistant steel are used for high-frequency quenching treatment to enhance wear resistance and maintain the original toughness.
BulletPoint3 : WIDE RANGE OF APPLICATIONS: Various chasing schemes can be selected to meet different use environments.
BulletPoint4 : WEAR-RESISTANT: Usually used in conjunction with linear bearing products, it has excellent linear guiding function. Compared with the general shaft and bushing structure, even if it is high-speed reciprocating motion, it will not have great wear.
BulletPoint5 : RUST PREVENTION: hard chromium plated surface treatment can be selected, which not only has excellent rust prevention performance, but also the coating hardness has reached hv750. It will not be easily worn when matched with high hardness workpieces.

1. Why is the guide shaft made of stainless steel rusted?
The stainless steel material used for the guide shaft is SUS440C or the same high hardness corrosion-resistant steel. It can have good wear resistance through quenching, but the corrosion resistance of its own material is weak. Therefore, if there are high requirements for rust prevention, please choose the surface treatment product plated with hard chromium.
2. The catalogue contains guide shaft products with high hardness. Why is the hardness measured on the center of the end face very low?
The heat treatment method of high-frequency quenching is used for the guide shaft, so a certain hardening layer depth will be formed on the outer shaft surface of the guide shaft. In order to ensure the toughness of the product, the original hardness of the material will still be retained at the center of the guide shaft.
3. What are the advantages of matching the guide shaft with the linear bearing?
Through the rolling friction fit between the guide shaft and the linear bearing, under the condition of realizing high-precision linear motion, it will not cause excessive friction resistance to the workpiece, and is suitable for long-term continuous operation.
