1. What Is Oil Seal Selection?

Oil seal selection involves choosing the appropriate seal size based on shaft diameter and required clearance for optimal performance and longevity in mechanical applications.

2. How Does The Calculator Work?

The calculator uses the following formula:

Where:

• \( Shaft Diameter \) — Measured shaft diameter in millimeters
• \( Recommended Clearance \) — Based on application requirements and clearance type

Explanation: The calculator determines appropriate clearance based on shaft size and selected clearance type (standard, tight, or loose) to recommend the optimal seal size.

3. Importance Of Proper Seal Selection

Details: Correct oil seal selection ensures proper sealing, prevents leaks, reduces wear, and extends equipment life. Improper sizing can lead to premature failure and equipment damage.

4. Using The Calculator

Tips: Enter shaft diameter in millimeters and select the appropriate clearance type based on your application requirements. Standard clearance works for most applications.

5. Frequently Asked Questions (FAQ)

Q1: What clearance type should I choose?
A: Standard clearance works for most applications. Use tight clearance for high-speed applications and loose clearance for rough surface conditions.

Q2: How do I measure shaft diameter accurately?
A: Use precision calipers and measure at multiple points along the shaft to account for any wear or irregularities.

Q3: What factors affect seal selection besides shaft size?
A: Temperature, pressure, speed, media being sealed, and shaft surface finish all influence seal selection.

Q4: Can I use this calculator for metric and imperial units?
A: This calculator uses metric units (mm). Convert imperial measurements to metric before calculation.

Q5: When should I consult a seal specialist?
A: For critical applications, extreme conditions, or when dealing with specialized media, consult with a seal manufacturer or specialist.
