Industry Pain Points & INDRON® Solutions
These persistent issues demand innovative material solutions that outperform conventional options.
Premature Bearing Failure: Metallic bearings corrode; rubber bearings deform
Lubrication Pollution: Oil leaks contaminate water sources
High Maintenance Costs: Frequent part replacements cause downtime
Sediment Damage: Sand/silt accelerates wear
High Starting Torque: Rubber bearings struggle with dry starts
Our advanced polymer technology directly addresses these challenges with measurable results.
Water Lubrication: Eliminates mineral oil pollution
Self-Lubricating: Embedded lubricating particles reduce maintenance
Superior Wear Resistance: 3-5x longer service life than conventional materials
Wide Temperature Range: Stable performance from -40°C to 110°C
Custom Engineering: Tailored solutions for specific operating conditions
