OEM Shock Oil Seal for Consistent Suspension System Reliability

This OEM shock absorber oil seal is engineered for consistent, long-term suspension performance. Featuring a double-lip design with premium NBR rubber and optional PTFE construction, it delivers superior sealing integrity, wear resistance, and reliability under demanding operating conditions. Manufactured under IATF16949:2016 quality management standards, every unit undergoes rigorous dimensional and material testing before shipment.

We manufacture oil seals in various dimensions to fit different shock absorber models. Below are sample dimensions for reference - custom sizes available upon request.

Production Equipment:

• Automatic Hydraulic Machines for precision forming
• Automatic Mechanical Pressers for consistent compaction
• Vacuum Furnaces for contamination-free sintering
• Sintering Furnace for controlled heat treatment
• CNC Tooling Machine for custom mold fabrication

Sintered Parts Capability:

As a professional Fe/Cu-based powder metallurgy parts manufacturer, our proven process flow includes: Mixing to Compacting to Sintering to Re-sizing to Ultrasonic Cleaning to Vacuum Oiling to Packing. This integrated approach ensures high precision, low noise, superior wear resistance, energy efficiency, and cost-effectiveness within a single quality-controlled pipeline.

• Comprehensive test equipment for crushing strength validation
• Dedicated QC and PQC teams maintain tight tolerances and dimensional accuracy
• Custom engineering support - we develop parts according to your drawings or samples

• Automotive Shock Absorber Systems
• Motorcycle Suspension Components
• Hydraulic Pump Assemblies
• Locomotive Damping Systems
• Industrial Machinery

Q: Can you produce oil seals with custom dimensions?

Yes. We manufacture oil seals based on customer-provided drawings or samples. Our CNC tooling capability allows us to produce non-standard dimensions with the same precision as our catalog items.

Q: What is the minimum order quantity (MOQ)?

Our standard MOQ is 1,000 pcs per order. For new customers requiring samples or trial orders, smaller quantities can be arranged upon discussion with our sales team.

Q: What quality certifications do you hold?

We are IATF16949:2016 certified, meeting the strictest quality management standards for automotive series production. All materials are tested per GB/T standards with full batch traceability from raw material to finished product.

Q: What materials are available for the oil seals?

Our standard material is NBR (Nitrile Butadiene Rubber) with proven performance across a wide temperature range. We can also supply PTFE, FKM (Viton), and silicone compounds upon request for specialized applications requiring chemical resistance or extreme temperature performance.

Q: How long does delivery take?

New sample development typically takes 30 working days. For repeat orders of existing specifications, delivery time depends on order volume - please contact us for a precise lead time estimate based on your requirement.

Q: How do you ensure consistent quality across batches?

Every production batch undergoes dimensional inspection (projector and caliper measurement), material property testing (Shore hardness, tensile strength, elongation), and oil resistance / thermal aging validation before release. Our electronic balance system ensures material density consistency from batch to batch.

Q: Do you offer samples for evaluation?

Yes, we provide samples for quality evaluation. Sample lead time is approximately 10 days. Please contact our sales team with your specific requirements for sample pricing and shipping arrangements.
