YOUR GUIDE TO SEALING OPTIONS

Understanding the variations in sealing types is essential for selecting the right bearings for your application. Metal shielded, rubber sealed, and PTFE sealed bearings each have unique characteristics that affect performance, maintenance, and cost. Metal shielded bearings, while budget-friendly, require regular cleaning compared to their rubber sealed counterparts which offer a tighter seal at the cost of higher friction.

CHOOSING THE RIGHT BEARINGS FOR YOUR NEEDS

Hobby enthusiasts can benefit from knowing the pros and cons of different bearing types. Metal shielded bearings excel in both on-road and high-temperature applications, while rubber sealed bearings are ideal for low maintenance in extreme conditions. PTFE sealed bearings merge high performance with low upkeep, and newer PolyAmide sealed bearings deliver excellent protection against debris with reduced heat absorption.
