Hydraulic Seal Kits Manufacturer 

1. What types of sealing products are commonly used in construction machinery?
Construction machinery relies on a variety of sealing components, each designed for specific applications:

Floating Seals: Used in slewing rings, travel motors, and other rotating joints, designed for high-pressure, high-temperature, and severe vibration conditions.

Complete Gasket Sets: Include engine, hydraulic system, and transmission gaskets for fluid containment and leak prevention.

Sealing Rings: O-rings, X-rings, Glyd-rings for high-pressure hydraulic systems, available in FKM, HNBR, and polyurethane.

Washers: Flat washers, spring washers, and serrated washers for secure fastening and anti-loosening.

Spacer Pads: Precision aluminum alloy or engineering plastic pads for accurate positioning and wear resistance.

2. How do I choose the right seal or gasket for my construction equipment?
Selection depends on:

Application area: Slewing rings, transmissions, hydraulic systems, or engines.

Operating conditions: Pressure, temperature, vibration, and chemical exposure.

Compatibility: Ensure the part matches OEM specifications for brands like CAT, Komatsu, Hitachi, or Volvo.

Material requirements: FKM, HNBR, silicon carbide, or composite materials depending on oil, heat, and wear resistance needs.

3. What materials are YLCM seals and gaskets made of?
YLCM uses advanced materials to ensure durability and reliability:

Floating seals: Silicon carbide and hard alloy composites, HRA90-92 hardness, Ra≤0.2μm surface roughness.

Gaskets: Multi-layer composite steel plates and fluoroelastomer materials, oil resistance per ASTM D471.

Sealing rings: FKM, HNBR, polyurethane with hardness 70–95 Shore A.

Washers: Stainless steel, copper alloys, or 65Mn spring steel with HRC42-48 hardness.

Spacer pads: High-strength aluminum alloys or engineering plastics, ISO 2768-m grade dimensional accuracy.

4. How does YLCM ensure the durability and performance of seals and gaskets?
Durability is ensured through:

Precision manufacturing: Dimensional tolerances within ±0.08–0.1mm, compliant with ISO 3601-3 and other standards.

Advanced material selection: High-temperature, high-pressure, and oil-resistant materials.

Performance testing: 8,000+ hour service life tests, high-pressure hydraulic cycle tests, environmental adaptability tests.

Design innovation: Unique double-cone floating seal design, precise spacer pad positioning, and optimized gasket structures.
