61802 61802tn1 Deep Groove Ball Bearing High Quality

Optimal Performance in Light to Medium Load Applications

Designed for operating environments where smooth rotation and low friction are critical, this bearing handles standard industrial conditions with ease. Its 9mm bore diameter, 20mm outer diameter, and 6mm width make it ideal for compact mechanical assemblies. The bearing steel construction ensures durability under continuous use, while the TN1 designation indicates a thermoplastic cage that reduces noise and improves lubricant retention.

Key Engineering Features for Consistent Operation

The single-row configuration provides simplicity in installation and maintenance, while the radial load capacity makes it suitable for non-thrust applications. The 0° contact angle ensures uniform load distribution across the raceways, minimizing stress concentrations during rotation. Measuring 9x20x6mm, this bearing fits standard metric housing and shaft sizes, eliminating the need for custom machining. The bearing steel material offers excellent hardness and wear resistance, essential for maintaining precision in high-revolution components.

Pourquoi Choisir le Bon Roulement Réduit les Coûts Totaux

Selecting a quality deep groove ball bearing like this 61802 model reduces long-term expenses by minimizing downtime and replacement frequency. Inferior bearings often fail early due to poor material quality, leading to unplanned maintenance and production losses. This bearing’s adherence to international standards ensures consistent performance, aligning with ISO 281 guidelines for bearing life calculation. By choosing a reliable component, you avoid the hidden costs of premature failures, such as damaged adjacent parts and labor for emergency repairs.
