The 75x130x31 mm Bearing A Comprehensive Overview Bearings play a crucial role in the mechanics of various machines and devices, serving as the pivotal element through which rotational motion is facilitated. Among the various sizes and types available, the 75x130x31 mm bearing stands out due to its unique dimensions and applications. This article will explore the significance, features, and uses of this particular bearing size in various industries. Understanding Bearing Dimensions The dimensions 75x130x31 mm refer to the bearing's inner diameter (ID), outer diameter (OD), and width (W), respectively. The first measurement, 75 mm, indicates the internal diameter, which is the part that fits onto the shaft. The second measurement, 130 mm, refers to the outer diameter, which is the external fitting for the housing. Lastly, the 31 mm width provides insight into how much space the bearing occupies in any assembly. These dimensions make the bearing suitable for a range of applications where strength and stability are necessary. Material and Design Typically, 75x130x31 mm bearings are constructed from high-grade steel, which provides durability and resistance to wear. Some variants may feature seals or shields designed to protect the internal components from contaminants such as dust, dirt, and moisture. The design of these bearings often includes ball elements or roller components, which help distribute loads evenly, reducing friction between moving parts. This design is critical in operating conditions where machinery components must withstand significant stress and varying temperatures. 75x130x31 bearing Applications Across Industries The versatility of the 75x130x31 mm bearing renders it advantageous across various sectors. In the automotive industry, these bearings are frequently utilized in wheel hubs, ensuring smooth rotation while supporting the weight of vehicles. Similarly, they find applications in heavy machinery, including construction equipment and agricultural vehicles, playing a significant role in enhancing operational efficiency and reliability.
