NSK Koyo Timken 6324 6328 6330 Zz Deep Groove Ball Bearings

Optimal Performance Under Radial Loads

Designed as a radial bearing with a 0° contact angle, the 6328 excels in applications where radial loads are primary. Its single-row, unseparated structure ensures stable operation at speeds up to the manufacturer’s recommended limits, while the 140mm bore diameter and 300mm outer diameter provide a robust load-carrying capacity. Whether used in electric motors or conveyor systems, proper dimension matching (140*300*62mm) is critical to prevent bearing failure and equipment downtime.

Principais Características de Engenharia para Longevidade

The bearing steel construction offers high surface hardness and wear resistance, essential for withstanding heavy loads and continuous use. Precision ratings (P0-P4) ensure dimensional accuracy, reducing vibration and noise in high-speed applications. For environments where maintenance access is limited, the 2RS sealed variant provides effective contamination protection, extending service intervals compared to open bearings. The Zz metal shields offer a balance of protection and heat dissipation, making them suitable for moderate temperature ranges.

Custo Total de Propriedade: Por que a Qualidade Importa

Choosing a low-quality 6328 bearing may save upfront costs but often leads to higher expenses later. Bearings with substandard material hardness or imprecise dimensions can cause excessive vibration, leading to premature wear of adjacent components and unplanned downtime. Our bearings, tested for size, hardness, and surface finish, align with international standards to minimize these risks. By reducing replacement frequency and maintenance needs, they contribute to a lower total cost of ownership over the long term.
