Needle roller bearings

• 1.Basic characteristics: It is a rolling bearing with cylindrical needle rollers with an aspect ratio of >3 as rolling elements. It has a compact structure and small radial dimensions. It can carry more load than ordinary bearings in the same space.
• 2.Core advantages: First, the radial load-bearing capacity is outstanding, suitable for medium and low speed and high load scenarios; second, the size is small, saving installation space; third, the inner and outer rings can be partially omitted, reducing equipment costs.
• 3.Common types and scenarios: The stamped outer ring type has low cost and is used in home appliances and textile machinery; the solid ring type has high precision and is suitable for automotive steering systems; the needle roller cage assembly is used in engineering machinery crankshafts.
• 4.Key points for use: Ringless models require guaranteed shaft/housing surface accuracy; lubricate regularly to prevent wear; not suitable for high speeds
