Product Description

Needle Bearing Introduction

Needle bearings feature slender rollers, offering high load capacity in a compact structure. We offer mainstream models (HK, BK, RNA, TAF) for diverse applications.

Made of high-quality alloy steel with precision heat treatment, they excel in wear resistance, rust proofing and durability, fitting auto, industrial and agricultural machinery.

Ideal for assembly, maintenance and spare parts, our bearings ensure stable operation. Strict quality control guarantees consistent quality and international interchangeability.

Our needle bearings cover multiple mainstream models, including HK, BK, RNA, TAF series, each tailored to specific application needs. HK and BK series are unidirectional thrust needle bearings, featuring simple structure and reliable load transmission, widely used in small mechanical components. RNA and TAF series are without inner ring, suitable for occasions where the shaft serves as the raceway, reducing overall weight and cost of the equipment.

Crafted from high-quality alloy steel with precision heat treatment, these needle bearings boast outstanding performance in wear resistance, rust prevention and long service life. They can withstand heavy loads, high speeds and harsh working environments, perfectly fitting scenarios such as auto transmission systems, industrial machinery, agricultural equipment, motors, generators and construction machinery.


Needle Bearing- Specifications

Specifications

Our needle bearings cover mainstream series including HK, BK, RNA and TAF, each with targeted characteristics. HK and BK series are unidirectional thrust needle bearings, featuring a simple structure and reliable load transmission, suitable for small mechanical components. RNA and TAF series are inner ring-free, designed for scenarios where the shaft acts as the raceway, effectively reducing equipment weight and overall cost. Crafted from high-quality alloy steel through precision heat treatment, these bearings possess excellent wear resistance, rust prevention and long service life, ensuring stable performance under high loads and high speeds.
Application Scenarios

With their compact structure and strong load-carrying capacity, our needle bearings are widely applied in multiple fields. They are perfectly suited for auto transmission systems, industrial machinery repair and assembly, agricultural equipment maintenance, motors & generators, as well as construction machinery spare parts. These bearings can adapt to harsh working environments, making them ideal choices for both new equipment assembly and spare part replacement, providing reliable support for global industrial and automotive industries.
