Extra Thin ET, ER Series Bearings
48 ProductsThe Extra Thin ET, ER Series Bearings represent the epitome of precision engineering in the realm of extremely thin section ball bearings, also known as extra thin ball bearings. They have inch and metric sizes. They inherit the features of thin section bearings and develop in the direction of ultra-thin wall.
Features of Thin Section Bearings
Extra Thin ET, ER Series Bearings inherit the advantages of common thin-section bearings, including:
- Compact Design
- Lightweight Construction
- Low Friction
- High Stiffness
- Excellent Running Accuracy
Features of ET, ER Series Bearings
ET, ER Series Bearings have minimized ring thickness, balancing load capacity with a slim profile. This results in lighter machinery, space-saving, and improved precision. While the load capacity is slightly compromised, these bearings are still robust, ideal for compact, lightweight applications. More
