Our commitment to quality ensures long service life and dependable operation in demanding industrial environments.
Applications:
Essential for sealing rotating shafts in granulators, shredders, and material processing equipment where lubricant retention and contamination prevention are critical. Ideal applications include:
• Rotor shaft seals in granulators and shredders
• Drive shaft sealing in material processing equipment
• Bearing housing seals protecting against contaminants
• Gearbox and transmission shaft sealing
• Motor shaft seals in industrial environments
• Recycling equipment operating in dusty or contaminated conditions
Installation Guidelines:
Preparation: Clean shaft and bore thoroughly, removing all debris and old seal residue
Lubrication: Apply thin film of compatible lubricant to seal lips and shaft surface
Orientation: Install with spring-loaded lip facing the fluid/lubricant side
Installation Method: Use proper seal installation tool or press; avoid hammering directly on seal
Shaft Condition: Ensure shaft surface is smooth and free from burrs or damage
Alignment: Install squarely to prevent cocking or damage to sealing lip
Maintenance & Service Life:
Inspection: Regularly check for leakage or deterioration during scheduled maintenance
Replacement Indicators: Visible lubricant leakage, hardening or cracking of rubber, visible wear on sealing lip
Service Life: Varies based on operating conditions, typically several thousand hours in normal industrial service
Storage: Store in cool, dry location away from direct sunlight and ozone sources
Shelf Life: Use within 5 years of manufacture for optimal performance
