Bottom rollers play a major role in ensuring yarn quality. Precise concentricity guarantees high yarn quality (evenness and strength). Equally influential to yarn breaks are the running conditions of the bottom rollers. Precise running bottom rollers allow to extend the spinning limits into finer yarn count ranges.
NIBL manufactures a wide range of Bottom Roller Bearings. These are specifically designed Needle Roller Bearings for long life and low maintenance for Ring Frames. The outer ring of the bearing is crowned to accommodate misalignment in the roller stands. Crowning also helps in preventing early failure of the bearing by distributing the load uniformly. The inner ring has knurling on its flanges, which provides an effective seal to prevent entry of fibres in the bearing and protect it from damage. NIBL Bottom Roller Bearings incorporate a steel cage split in two halves or plastic cage. The design of cage pockets ensures that the needles do not fall and also give them positive and accurate guidance. Lubrication to the bearing is effected through the grease nipple. The bearing is secured on the roller stand very easily by a holder (locating cap). The holder (locating cap) can be customized according to unique application designs.
