When mud packs tightly around a conventional seal, the seal can become the first weak point in the drivetrain. Integrated COMBI Seals help create a stronger contamination barrier while retaining internal lubricant.
Product type: severe-duty rotary seal
Seal family: COMBI
Core benefit: heavy-mud exclusion
Pain point: packed mud around seal
Mud type: wet soil and clay
Dust type: dried abrasive particles
Grit control: external debris exclusion
Lubricant retention: helps protect grease
Bearing protection: reduces ingress risk
Shaft protection: reduces abrasive tracking
Primary lip protection: integrated shielding
Secondary exclusion: contamination barrier
Splash handling: suitable for muddy service
Ingress control: helps block external paths
Leakage control: supports lubricant containment
Wear objective: reduce packed-debris wear
Reliability objective: longer service consistency
Uptime objective: fewer unplanned stops
Maintenance objective: extend planned intervals
Spare-part objective: reduce repeated seal use
Application: wheel hubs
Application: axles
Application: gear housings
Application: rotating shafts
Industry: construction
Industry: agriculture
Industry: earthmoving
Environment: mud-heavy field service
Duty: severe contamination cycling
Rotation: continuous/intermittent rotary duty
Design: integrated COMBI architecture
Material: application-specific elastomer/metal support
Size: shaft, bore and width matched
Speed: verify lip surface speed
Temperature: verify service temperature
Pressure: confirm pressure exposure
Shaft finish: smooth, compatible track required
Housing condition: clean, round and secure
Installation: prevent lip folding or cuts
Inspection: check packed debris and grease condition
Replacement trigger: leakage, cracks or worn running track
Heavy-mud applications should be specified from the contamination load and maintenance history, not from catalog dimensions alone.
