Needle roller bearings are compact rolling bearings featuring slender needles (with lengths exceeding their diameters by 3 to 10 times) that roll between inner and outer rings, enabling efficient power transmission and load-bearing capabilities. Characterised by their compact structure, high load capacity, and suitability for high rotational speeds, they find extensive application in automotive, mechanical engineering, aerospace, and other industries.
Key Features:
High load capacity: The needle's length exceeds its diameter, providing a large contact area that can withstand substantial radial loads. Its load-bearing capacity per unit volume is 2-3 times that of ball bearings of equivalent dimensions.
Compact structure: With a small radial cross-section, it offers the smallest outer diameter when matching the inner diameter and load capacity of other bearing types. This makes it particularly suitable for installation environments with limited space.
Low friction and high efficiency: Their rolling friction characteristics yield a friction coefficient far lower than sliding bearings, typically ranging from 0.001 to 0.005, effectively reducing energy loss.
High precision and extended service life: Manufactured from wear-resistant materials and subjected to precision machining and heat treatment, they offer high manufacturing accuracy and a prolonged operational lifespan.
