Product detailed description

Bearing - 6906 2RS NTN

NTN 6906 2RS – thin-section bearing with contact seals on both sides

NTN 6906 2RS is a single-row deep groove ball bearing with a small radial cross-section. The corresponding NTN catalogue design 6906LLU/5K has contact seals on both sides and a pressed-steel cage. It accommodates radial loads and moderate axial loads in both directions.

Technical data

• Fatigue load limit Cu: 0.365 kN
• Radial internal clearance: CN
• Grease-lubrication limiting speed: 8,400 rpm
• Operating temperature: −25 to +110 °C
• Mass: approximately 0.048 kg;minimum fillet radius: 0.3 mm

Sealing, application and mounting

Contact seals on both sides help retain lubricant and protect the rolling contact from ordinary contaminants. They generate more friction than non-contact shields, so the speed and temperature limits of this exact variant must be observed.

Before ordering, compare the generic 2RS designation with the physical NTN LLU/5K suffix and verify the required CN clearance. During mounting, check shaft and housing fits and transmit fitting force only through the ring being pressed into position. The stated values are based on NTN-SNR catalogue data for 6906LLU/5K.
