What Are Oil Seals?
Oil seals are small but essential mechanical sealing parts, also called radial shaft seals. They are widely used in cars, trucks, hydraulic machines, industrial equipment, and various mechanical devices.
The main job of oil seals is to stop lubricant oil leakage, keep dust, dirt, water and other impurities out of the machine, and protect internal parts like bearings and gears from damage. They help reduce machine wear, extend service life, and lower maintenance costs.
Main Types of Our Oil Seals
TC Type Oil Seals
The most commonly used type, double rubber lip with spring, good sealing effect, wear-resistant. Suitable for most automotive engines, gearboxes, and general industrial machines.
NBR Oil Seals
Standard rubber material, oil-resistant, cost-effective, perfect for daily normal working conditions, universal for most equipment.
FKM Oil Seals
High-temperature resistant, corrosion-resistant, durable for heavy-duty, high-pressure and extreme working environments.
Common Signs of Damaged Oil Seals
• Visible oil leakage around machine shafts
• Equipment runs with abnormal noise
• Dust gets inside mechanical parts
• Faster wear of internal components
Once you find these problems, please replace the oil seal in time to avoid bigger equipment failure.
Installation & Maintenance Tips
1. Clean the shaft and mounting hole completely before installation
2. Use proper tools to install, do not scratch the rubber lip
3. Choose the correct size oil seal for a perfect fit
4. Check and replace worn oil seals regularly
5. Keep the working environment clean to reduce impurity erosion
