Searching for the right cylindrical roller bearing often means sifting through countless models across brands like Koyo, Timken, and NSK. Mismatched dimensions can lead to installation delays, while poor material quality results in premature wear—costing your operation time and money. Projetado para oferecer desempenho consistente
Our cylindrical roller bearings, including models N321em, N322em, and N324em, address these challenges with precision manufacturing. As a专业轴承供应商 with ISO 9001-certified production processes, we ensure each bearing meets strict dimensional standards (20*52*12mm for the 6304 series) and material requirements. With access to both our own BDL brand and international brands like NSK and Timken, we simplify sourcing by offering one-stop access to multiple options. Ideal para aplicações com carga radial
Designed as single-row radial bearings with a 0° contact angle, these cylindrical roller bearings excel in applications with high radial loads and moderate speeds. Common uses include electric motor shafts, gearbox assemblies, and conveyor rollers—where reliable load distribution and minimal friction are critical. Their bearing steel construction provides the durability needed for continuous operation in industrial environments. Principais características de engenharia explicadas
The 20mm bore diameter (d), 52mm outer diameter (D), and 12mm width (B) dimensions follow international standards, ensuring interchangeability with major brand equivalents. The single-row design balances load capacity with compact size, making it suitable for space-constrained installations. Bearing steel material offers excellent hardness and wear resistance, while the 0° contact angle optimizes radial load handling—critical for preventing shaft misalignment and extending service life. Por que Rolamentos de Qualidade Reduzem o Custo Total
Choosing a precision cylindrical roller bearing directly impacts your equipment’s reliability. Inferior bearings often fail early due to substandard material hardness or imprecise dimensions, leading to unplanned downtime and costly repairs. Our bearings undergo rigorous testing—including dimensional checks and hardness verification—to meet ISO standards, reducing the risk of premature failure. While initial costs may be slightly higher, the extended service life and reduced maintenance needs lower your total cost of ownership over time. Qualidade em que você pode confiar
Our production and inspection processes are ISO 9001 certified, ensuring consistent quality from raw material testing to final product inspection. We verify critical parameters like dimensions, hardness, and surface finish for every batch. All bearings come with a warranty against manufacturing defects, and we stand behind our products with responsive customer support. With extensive inventory and the ability to source from multiple brands, we can fulfill both small and large orders efficiently.
