Glparts Cylinder vs Regular Cylinder

1. Cylinder Material: 25Mn vs Common 20# Steel
Glparts Cylinder: Premium 25Mn Steel

• Over 30% higher compressive strength than 20# steel
• Superior fatigue resistance for high-impact operations
• Improved wear resistance, extending service life even in harsh environments

Regular Cylinder: Standard 20# Carbon Steel

• Lower strength and durability under heavy load
• More prone to deformation and rust
• Shorter lifespan, especially under continuous use

2. Welding Process: Fully Automatic vs Manual Welding
Glparts Cylinder: Fully Automated Robotic Welding

• Uniform weld seams with consistent strength
• Fewer defects like pores or slag inclusions
• Clean appearance and stronger structural integrity

Regular Cylinder: Manual Welding

• Inconsistent quality due to human error
• Uneven weld penetration increases risk of cracking
• Less reliable under long-term stress

3. Seal Quality: Branded Imports vs Generic Domestic Seals
Glparts Cylinder: Imported NOK & SKF Seals

• Sourced directly from Japan (NOK) and USA (SKF)
• Excellent resistance to high pressure, heat, and oil contamination
• Leakage rate controlled to below 1%, even in dusty or humid environments

Regular Cylinder: Generic Local Seals

• Lower reliability in extreme temperatures or heavy-duty usage
• Higher chances of early leakage and seal failure
• Less suitable for long-term, high-load applications
