Because the special solid lubricant is embedded, it eliminates the need for lubrication. (Applying initial running–in oil prior to use can enhance the product's durability furthermore.) Please pay attention to the mold temperature as oil will ooze out from the solid lubricant at 80°C or higher temperatures.

E The inner diameter of the bushing for EGBPK is coated with a coating agent (black) to secure heat resistance and initial running. E Depending on the coating agent, it may be difficult to insert leader pins, etc. Note that initial running may not be secured if the coating is removed. E The coating agent can be removed using organic solvents, etc. E The inner diameter tolerance of this product is F6.

Example of EGBNZ/EGBZ/EGBSK usage • When using commercial mold bases, there are two ways–either to make the counterbore on the upper or lower plate. In contrast to the short guide type EGBH ( P.880 ) ejector leader bushings, EGBN ( P.880 ) and EGBNZ/ EGBZ/EGBSK provide a longer leading distance regardless of which plate the counterbore is based. 使用例 Example
