INA needle roller bearings are a type of bearing based on modular design, the basic element of which is the needle roller, which is gradually combined with components such as cages, stamped outer rings, inner and outer rings and seals to form a series of bearings that meet a wide range of engineering and technical needs. Low wear design: INA needle roller bearings have low wear characteristics, which makes them perform well in long-term operation and reduces maintenance requirements. High transmission life: These bearings use high-quality materials and precision manufacturing processes to ensure high transmission life and good pressure resistance. Wide range of applications: Due to their modular design, INA needle roller bearings can meet various engineering needs and are suitable for a variety of mechanical equipment. INA needle roller bearings are widely used in various mechanical equipment, especially in situations where high transmission efficiency and low maintenance costs are required. They are often used in the fields of automobiles, textile machinery, automation equipment, etc.
INA needle roller bearings redefine power density through extended roller geometry (length-to-diameter ratios of 4:1–10:1), enabling 300 kN/cm² radial load capacity in cross-sections 50–70% thinner than conventional bearings. Designed to DIN ISO 3245 standards, these bearings excel where space constraints and shock loads challenge traditional solutions – from automotive transmissions to robotics and aerospace actuators.
