Direct Engineering Summary:
The Industrial O-Ring Seal (Profile O-RING / Material FKM) is an industrial-grade sealing solution manufactured from FKM / Viton® Fluorocarbon Elastomer (75–80 Shore A). Engineered to eliminate High-temperature rotary shafts causing conventional NBR seals to harden, crack, and leak prematurely, it supports operating temperatures of -20°C to +200°C (Peak +230°C), pressures of Up to 100–400 Bar (with Back-up Ring), and surface speeds of Up to 15 – 35 m/s. Available in stock at SEALTHAI starting from ฿125 THB.

1. Field Problem Analysis & Engineering Solution

In industrial machinery, power transmission gearboxes, and hydraulic cylinders, a leading cause of unplanned downtime is High-temperature rotary shafts causing conventional NBR seals to harden, crack, and leak prematurely. Selecting an inferior elastomer or mismatched profile accelerates lip wear and lubricant leakage.

SEALTHAI Engineering Solution: Engineered with genuine FKM (Viton) fluorocarbon rubber rated for continuous 200°C operation, preventing thermal hardening and chemical swelling.

5. Engineering Installation Checklist & Limitations

  1. Dimension Verification: Measure the actual shaft diameter (ID), housing bore diameter (OD), and groove width (THK) in millimeters using a calibrated digital vernier caliper.
  2. 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.
  3. 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.
