About Ejector Leader Bushings

Ejector leader bushings are precision-bore components pressed into the ejector retainer plate to receive ejector leader pins. They ensure smooth, low-friction ejector plate travel with H7 bore tolerance. Available in CAC301 bronze (standard), steel (economy), and oil-free composite (cleanroom) materials.

Application Scenarios

🔧

Standard Ejector Assemblies

Standard mold ejector assemblies need reliable, economical guide bushings that pair with EGH/EGHC pins.

Why it fits: CAC301 bronze provides low friction against SUJ2 pins with predictable wear patterns — the industry standard pairing.

Recommended:EGH Bushing — Bronze, Flanged
🏥

Cleanroom Ejector Systems

Cleanroom molds cannot use oil-lubricated ejector guidance.

Why it fits: Oil-free ejector bushings with embedded PTFE eliminate lubrication requirements entirely.

Recommended:Ejector Bushing — Oil-Free

Frequently Asked Questions

Which ejector leader pin type pairs with each bushing series?+
EGH pins pair with EGH bushings, EGHC pins with EGHC bushings. Never cross-match — shoulder dimensions and bore depths differ between series.
What clearance fit is standard for ejector guide bushings?+
H7 bore tolerance mating with g6 pin shaft. For Ø16 mm: bore 16.000-16.018 mm, shaft 15.989-15.978 mm.
Can ejector leader bushings be used without oil lubrication?+
Standard bronze bushings require grease every 10K-20K cycles. For oil-free operation, use the PTFE-embedded oil-free bushing variant.
