What is 1308 PCD? A Complete Guide to Pitch Circle Diameter
In the world of manufacturing, machining, and engineering, precise measurements are everything. One critical, yet often misunderstood, specification is the Pitch Circle Diameter, or PCD. If you’ve encountered the term **1308 PCD**, you’re likely dealing with components like wheels, gears, or flanges. This guide will demystify what 1308 PCD means, why it’s important, and how it’s used across industries.
Understanding Pitch Circle Diameter (PCD)
Pitch Circle Diameter is the diameter of an imaginary circle that passes through the center of all the bolt holes or studs on a mounting hub. It’s a fundamental measurement for ensuring proper fitment and alignment. The number “1308” specifically refers to a PCD of 130.8 millimeters. This measurement is common in various heavy-duty and automotive applications.
How to Measure PCD Accurately
For a 4-bolt pattern, you simply measure the distance between the centers of two opposite holes. For 5-bolt or other patterns, special formulas or gauges are used. Accurate measurement of your **1308 PCD** is crucial to avoid installation issues and ensure safety.
Common Applications of 1308 PCD
This specific PCD is frequently found in commercial vehicles, industrial machinery, and specialized equipment. It’s a standard for certain truck wheel hubs, large gear assemblies, and mounting plates where high load capacity and secure fastening are required.
Importance in Component Compatibility
Using a wheel or hub with an incorrect PCD is not possible—the bolts will not align. Therefore, knowing your exact PCD, such as **1308 PCD**, is the first step in sourcing compatible parts. For components like PDC cutters, precise dimensions like PCD are vital for tool performance. You can learn more about specialized cutters at 1308 PCD.
Frequently Asked Questions (FAQ)
Q: Is 1308 PCD the same as 130.8mm?
A: Yes, 1308 PCD denotes a Pitch Circle Diameter of 130.8 millimeters.
Q: Can I fit a 130mm PCD wheel on a 130.8mm hub?
A: No. Even a small 0.8mm difference in PCD will prevent proper bolt alignment and is unsafe.
Q: Where can I find parts with a 1308 PCD specification?
A: Specialized industrial suppliers and manufacturers of heavy-duty components typically stock or can produce items with this specification.
Conclusion and Next Steps
Understanding **1308 PCD** is essential for engineers, mechanics, and procurement specialists. It ensures interoperability, safety, and performance in mechanical systems. Always double-check this specification before purchasing or installing wheels, hubs, or other mounted components.
