■ Characteristics • This type has two oil grooves, one on the sliding part and the other on the pin side of the straight locating block set (TBSF D Left page ). • The oil grooves ensure that oil is fed to the sliding part, thus preventing the positioning straight block set from scuffing or seizing.

Delivery
■ When using • When the convex side and a concave side knock against each other, it causes dam- age. Please open about 1 mm and use it.
When positioning is begun
Mold closed
■ Characteristics • Suitable for positioning in precision molds such as connector and electronic device. • It is capable of preventing wear and damage in core pins since it can be positioned before core pins are inlayed on cavity. • Use precision leader pins since clearance is fairly small.
