View DetailsHow Oil Groove Patterns Affect Lubrication Performance
Oil grooves machined into the bushing bore create channels that distribute lubricant across the full contact surface as the leader pin slides in and out. The groove pattern determines how effectively oil is spread and retained:
- Helical (spiral): Best overall performance. The spiral path distributes oil continuously during pin travel. Recommended for high-cycle production molds.
- Axial (straight vertical): Simplest to machine. Oil flows by gravity from top to bottom. Adequate for standard molds but uneven distribution at horizontal positions.
- Cross-hatch (diamond): Maximum oil retention. The intersecting channels trap oil in diamond-shaped pockets. Best for intermittent operation where oil must be retained during idle periods.
All patterns reduce the friction coefficient from 0.15 (dry boundary) to 0.005-0.02 (hydrodynamic film), extending bushing life 2-4x vs plain.

About Oil-Groove Leader Bushings
Oil-groove leader bushings feature precision-machined channels in the bore surface that distribute lubricant across the full leader pin contact area. The grooves create a hydrodynamic oil film that reduces friction by 90%+ compared to dry contact, extending bushing service life 2-4x. Available in helical, axial, and cross-hatch patterns in CAC301 bronze.
Application Scenarios
High-Cycle Production Molds
Production molds running 24/7 need maximum lubrication interval to minimize maintenance downtime.
Why it fits: Helical oil grooves provide continuous oil distribution during every pin stroke, extending lubrication intervals to 20K-50K cycles (vs 5K-10K for plain).
Molds with Long Idle Periods
Molds that sit idle between production runs lose lubrication from gravity drainage, causing dry-start wear.
Why it fits: Cross-hatch grooves trap oil in diamond-shaped pockets that resist gravity drainage, maintaining lubrication even after weeks of idle time.
