The shaft is heat-treated and then machined.Due to heat treatment, the hardness of the female screw machining part ± 10mm before and after may decrease (see example below).
In addition, the heat treatment area is not within the guaranteed range of the outer diameter dimensional tolerance.When calculating the stroke, subtract the dimensions of the heat treated part.
When shipping miniature ball bushings, anti-rust oil is applied. Please wash and dry them, then apply grease before use.
Depending on the usage environment, replenish lithium soap-based grease (such as Alubania Grease S2 made by Showa Shell Sekiyu) as needed.
