• Material: 20CrMnTi / 40Cr high-strength structural steel
• Heat treatment: Carburizing & quenching or overall quenching & tempering
• Surface hardness: HRC 45–55
• Fit tolerance: Inner hole H7, outer diameter h6/h7 precision class
• Surface treatment: Blackening / phosphating for rust prevention
• Inner wall finish: Ra ≤ 0.8μm
• Operating temperature: -40℃～120℃
• Features: Wear-resistant, compression-resistant, precise guiding, anti-deformation, low spring friction

Application Scenarios

• Brake caliper piston return spring guide area
• Transmission shift fork spring and control valve spring guide bore
• Clutch mechanism and hydraulic valve assembly spring positioning area

  Works with springs, pistons and pins under high-frequency reciprocating, vibration and oil-immersed conditions.

Common Faults & Troubleshooting

• Inner wall wear & scoring: Causes spring sticking and increased friction. Replace 3236623 and check spring deformation.
• Deformation & out-of-roundness: Caused by overload extrusion. Replace with new sleeve to keep spring centered.
• Rust & seizure: Due to mud and debris intrusion. Clean and replace sleeve, improve sealing and lubrication.
• Fracture & chipping: From impact load or material fatigue. Replace sleeve and check assembly clearance and force status.
