Texparts® Bottom roller bearings

Precision needle bearings with high load bearing capacity

Among the machine components responsible for yarn quality, top rollers and bottom rollers are by far the most important. Precise concentricity guarantees high yarn quality (evenness and strength).

Bottom roller bearings UL are used in ring spinning machines and roving frames as well as airjet spinning machines. As top-quality needle bearings they decisively contribute to spinning quality and operational safety under conditions of high load and speed.
