NA4824 Needle Roller Bearing 120x150x30mm With Inner Ring High Radial Load For Reducer Gearbox Machinery

• NA4824 is a single row machined outer ring needle roller bearing supplied with a separable inner ring, overall dimensions 120×150×30 mm. It is precision crafted from high toughness GCr15 bearing steel, fitted with stamped steel cage to evenly guide needle rollers.Equipped with a complete hardened inner ring, it can be mounted directly without special treatment on the matching shaft, greatly simplifying assembly work. It features ultra-small radial cross-section and extremely high radial load capacity, ideal for installation spaces with limited radial size under heavy load conditions. The open design allows convenient grease filling and regular maintenance for long-term stable operation.
