Product Overview: H 3938 Adapter Sleeve
The H 3938 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 190mm diameter. As a key component in our H 3900 Series, this sleeve simplifies the process of securing bearings, allowing them to be positioned at any point on a smooth shaft without the need for shoulders or other locating features. This assembly, part of our broader Adapter Sleeves collection, includes the adapter sleeve, a corresponding lock nut, and a lock washer, providing a complete and secure mounting solution for demanding industrial applications.
Manufactured from durable steel, the H 3938 adapter sleeve ensures a tight and reliable fit, facilitating full contact between the bearing's inner ring and the shaft. This enhances operational stability, simplifies installation, and allows for easy dismounting for maintenance or replacement, making it a cost-effective and efficient choice for a wide range of machinery.
