Understanding the Dimensions and Specifications of 6403 Bearings Bearings are crucial components in various mechanical systems, providing support and reducing friction between moving parts. Among the numerous bearing types available, the 6403 bearing is a widely utilized option, known for its unique dimensions and capabilities. This article delves into the specifications and dimensions of 6403 bearings, explaining their importance and applications in various industries. What is a 6403 Bearing? The 6403 bearing is part of the deep groove ball bearing family, which is renowned for its simplicity and versatility. These bearings are designed to handle both radial and axial loads, making them suitable for various applications, from electric motors to automotive assemblies. The 6403 designation refers to specific dimensional attributes in accordance with ISO standards. Dimensions of 6403 Bearings The standard dimensions for a 6403 bearing are as follows - Inner Diameter (ID) 17 mm - Outer Diameter (OD) 62 mm - Width 17 mm These measurements make the 6403 bearing a medium-sized option, offering a balance between load capacity and compact dimensions. The inner diameter allows for mounting on shafts with a diameter of 17 mm, while the outer diameter provides stability and support within the housing. With a width of 17 mm, the bearing maintains a slim profile, suitable for various space-constrained applications. Load Ratings The load ratings are a critical aspect of any bearing's specification. For the 6403 bearing, the dynamic load rating (C) is approximately 20.5 kN, while the static load rating (C0) is around 10. 5 kN . These ratings denote the maximum loads the bearing can sustain under dynamic and static conditions, respectively. The ability to manage these forces is vital for maintaining the integrity and longevity of machinery. 6403 bearing dimensions Materials and Design Typically, 6403 bearings are made from high-quality chrome steel or stainless steel, enhancing durability and wear resistance. Some variations may incorporate ceramic materials, offering advantages in certain environments, such as high-speed or corrosive conditions. The design includes deep grooves that facilitate the rolling elements' motion, contributing to reduced friction and heat generation.
