Self-Lubricating Bushing Maintenance Guide
Low maintenance ≠ no maintenance
Graphite-plugged bronze bushings remove the grease gun from your routine — but a few checks keep them alive for years.
Routine checks
- Inspect the graphite plugs — they should wear level with the bore. Recessed plugs mean the bronze is carrying the full load.
- Watch temperature — a persistent temperature rise signals overload or misalignment, not lubrication failure.
- Check clearance — measure bore wear at each overhaul; replace when clearance exceeds 1.5–2× the original fit.
- Keep it clean — in abrasive dust, protect the exposed bore from direct grit ingress where possible.
When to rebuild
If the bronze itself is worn or the housing is damaged, we can machine a replacement to the original fit, or re-sleeve the housing.
Send the part dimensions or the worn sample — we will quote a direct replacement.
