Thaimart SEALTHAI
Direct Engineering Summary:
The Hydraulic Piston & Rod Seal (Profile TC/SC) (Profile TC/SC / Material PU) is an industrial-grade sealing solution manufactured from High-Pressure Polyurethane PU (92–95 Shore A). Engineered to eliminate Hydraulic cylinder pressure drop, rod drift, and seal extrusion or tearing under heavy shock loads, it supports operating temperatures of -35°C to +100°C (Peak +110°C), pressures of Up to 250 – 400 Bar (Heavy-duty hydraulic cylinders), and surface speeds of 0.5 – 1.5 m/s (Reciprocating Stroke). Available in stock at SEALTHAI starting from ฿202 THB.
1. Field Problem Analysis & Engineering Solution
In industrial machinery, power transmission gearboxes, and hydraulic cylinders, a leading cause of unplanned downtime is Hydraulic cylinder pressure drop, rod drift, and seal extrusion or tearing under heavy shock loads. Selecting an inferior elastomer or mismatched profile accelerates lip wear and lubricant leakage.
SEALTHAI Engineering Solution: High-modulus European-grade Polyurethane (PU) withstands up to 400 Bar with 4x higher abrasion and extrusion resistance than standard rubber.

5. Engineering Installation Checklist & Limitations
- Dimension Verification: Measure the actual shaft diameter (ID), housing bore diameter (OD), and groove width (THK) in millimeters using a calibrated digital vernier caliper.
- Counterface Surface Finish: Ensure the shaft surface roughness is within Ra 0.2 – 0.8 µm with hardness HRC ≥ 45. If the shaft has a wear groove, install a Shaft Repair Sleeve prior to mounting the new seal.
- Lead-In Chamfer & Pre-Lubrication: Verify a 15° – 30° lead-in chamfer on the shaft edge and lightly lubricate the sealing lip before installation to prevent dry-start scoring or garter spring dislodgement.
