1. What types of sealing and fastening components does YLCM offer?
YLCM provides a comprehensive range of components for heavy equipment:
Sealing Components:
O-rings: FKM rubber, wide temperature range (-40°C~250°C), chemical and hydraulic fluid resistance.
Oil seals: PTFE or hydrogenated NBR, precision surface finish (Ra≤0.4μm), high-speed applications (up to 30m/s).
Water seals: Reinforced EPDM, durable for submerged operation (5,000+ hours), resistant to steam, ozone, and chemicals.
Gaskets: Multi-layer steel or graphite for turbocharger and exhaust systems.
Sealants: Anaerobic, high tensile strength, petroleum-resistant, room-temperature fast curing.
Fastening Components:
Bolts: Grade 12.9 (40CrMoV), ≥1220MPa tensile strength, 95-100% thread engagement.
Nuts: Grade 12, prevailing torque design for anti-vibration performance.
Washers: 65Mn steel, HRC45-50, 0.025mm parallelism.
Bushings: Bronze-steel PTFE-impregnated, self-lubricating, 3x wear resistance.
2. How do I select the right sealing or fastening component for my equipment?
Selection depends on:
Operating conditions: Temperature, pressure, vibration, and exposure to fluids or chemicals.
Load requirements: Torque, preload, and fatigue resistance for fasteners; sealing pressure for seals.
Machinery compatibility: Check OEM specifications and part numbers for proper fit.
Maintenance and service intervals: Self-lubricating or durable materials can reduce downtime.
3. What materials are YLCM sealing and fastening components made of?
YLCM uses advanced materials for extreme conditions:
FKM rubber, PTFE composites, and EPDM for seals.
Multi-layer steel and graphite for gaskets.
Anaerobic formulations for fast-curing sealants.
40CrMoV alloy steel for high-strength bolts, nuts, and washers.
PTFE-impregnated bronze-steel for self-lubricating bushings.
These materials ensure corrosion resistance, high wear tolerance, and long-term durability.
4. How does YLCM ensure durability and reliability?
Durability is achieved through:
Precision manufacturing: Laser machining, strict dimensional tolerance, and batch testing.
