Deep groove ball bearing SKF 6208-2RS1N, Outer diameter: 80 mm | Width: 18 mm | Inner diameter: 40 mm

Ball bearings are essential mechanical components that reduce friction and support various loads in a wide range of industrial applications. Among them, deep groove ball bearings stand out for their versatility, ability to operate at high speeds, and low maintenance requirements.

This SKF deep groove ball bearing with a retaining ring groove and integrated seals is designed to deliver reliable, long-lasting performance in a variety of industrial environments. Featuring rubber lip seals on both sides, it ensures excellent protection against contaminants while keeping the lubricant inside. Thanks to these features, this bearing ensures quiet operation with moderate friction, even at high speeds.

Features:
This bearing is equipped with nitrile-butadiene rubber (NBR) seals on both sides, forming an effective barrier against dust, water, and other particles. These seals also help retain the lubricant, thereby extending the bearing’s service life. Its sheet steel cage ensures good resistance to continuous radial loads. Its standard radial clearance (CN) helps minimize friction and noise, even at high rotational speeds. The groove on the outer ring accommodates a retaining ring for simpler and more secure axial mounting.

Maintenance:
Thanks to the rubber seals, this bearing requires little maintenance, as it effectively retains the lubricant inside and protects against external contaminants. Its standard radial clearance (CN) also requires only moderate maintenance. However, it is recommended to perform periodic checks of noise and temperature to ensure that the bearing is operating optimally.

Sealing:
The NBR rubber lip seals on both sides provide excellent sealing, preventing the intrusion of contaminants such as dust or moisture. In addition, these seals offer superior resistance to corrosion and certain chemicals, such as industrial oils and greases. This enhanced protection helps keep the lubricant inside the bearing, thereby extending its service life, particularly in humid or dusty environments. Although the seals slightly increase friction resistance, they greatly optimize the product’s reliability under harsh conditions.
