Deep groove ball bearing NTN 6902LLB/5K, Outer diameter: 28 mm | Width: 7 mm | Inner diameter: 15 mm

This deep-groove ball bearing from the brand NTN is excellently suited for taking up radial and axial loads. It impresses with a low coefficient of friction and an exceptionally long service life. Thanks to the non-contact seals it achieves high speeds with minimal wear. It is ideal for demanding applications where a robust, quiet, and high-performance bearing is required.

Features:
With its deep raceways in the inner and outer ring, this deep-groove ball bearing accommodates high radial loads as well as moderate axial loads in both directions. The stamped steel cage ensures high resistance to continuous loads while also absorbing occasional shocks. The non-contact NBR seals with metal reinforcement prevent the ingress of contaminants such as dust and fine particles. At the same time they generate only a low starting torque, which reduces energy consumption and ensures smooth running. The bearing is suitable for high speeds and reduces vibration and noise due to its standard radial clearance. It is factory-filled with the high-performance grease "5K" (Multemp SRL) – a biodegradable lubricant with a wide operating temperature range.

Maintenance:
Since this bearing is pre-greased with the grease "5K" (Multemp SRL), maintenance is limited to regular visual and functional inspections regarding noise, temperature, and vibrations to detect any anomalies early.

Seals:
The non-contact seals of this bearing form an effective barrier against dust and fine particles, but provide only limited protection against moisture. Compared to metal shields, lubricant retention is improved; however, the sealing is less tight than with rubber seals.
