Bulwark Bearing Guard

The Bulwark Bearing Guard is a heavy-duty, non-contacting bearing isolator. It forms a robust barrier against contaminants, significantly extends wear-life and can be retrofitted into legacy pumps without major modification.

Protects bearings from contaminants

In high throughput mineral-processing environments, bearing failures often stem from contamination, ingress and inadequate sealing. The Bulwark Bearing Guard uses a non-contact stainless-steel isolator and integrated splash guard design to protect the bearing housing even under high pressure gland leakage or heavy dust exposure.

Includes:
  • Non-contacting stainless-steel bearing isolator that eliminates wear on the seal face.
  • Recessed design prevents dust, mud or debris build-up on the sealing face.
  • Splash-guard and labyrinth mechanism channel lubricant back to the bearing housing and eject contaminants via centrifugal force and gravity.
  • Retrofit kit available for many legacy frames and rotating equipment including pumps, electric motors, gear boxes, compressors and turbines.
Features and benefits

Installing the Bulwark Bearing Guard helps maintenance teams reduce unplanned stops, simplify spares stock and extend bearing life, all while supporting safe, efficient operations.

  • Significantly longer wear-life, at least twice that of conventional bearing isolator systems.
  • Reduced contamination ingress, keeping bearing housings cleaner and with less buildup.
  • Lower maintenance burden — fewer interventions, less downtime.
  • Simplified retrofit process — compatible with many legacy systems, avoiding full equipment replacement.
  • Enhanced reliability in harsh mining-site environments (dust, slurry, high-pressure spray).
  • Consolidated spare-parts inventory — one solution adapts across multiple machine types.
