Deep groove ball bearing SKF 6311-2RS1/C3, Outer diameter: 120 mm | Width: 29 mm | Inner diameter: 55 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 ball bearing is ideal for supporting radial and axial loads in both directions, while ensuring easy installation. Thanks to its innovative design and high-quality construction, this bearing stands out for its ability to operate efficiently even in demanding environments.

Features:
This single-row deep groove ball bearing features a sheet steel cage that provides exceptional strength. Equipped with rubber lip seals on both sides, it offers effective protection against contaminants while retaining lubricant inside. With an internal radial clearance of C3, it enables high rotational speeds while reducing internal friction.

Maintenance:
This deep-groove ball bearing is designed to require minimal maintenance, thanks to its rubber seals that keep the lubricant inside and protect against particle intrusion. However, it is advisable to regularly monitor operating conditions, such as temperature and vibration, to detect any abnormalities. Periodic inspections of temperature and operating noise are also recommended to extend the product’s service life.

Sealing:
This bearing is equipped with nitrile-butadiene rubber (NBR) lip seals, which provide excellent sealing. This design prevents dust and moisture from entering while keeping the lubricant inside. Although this sealing helps extend the bearing’s service life, it is important to note that these seals may introduce slight resistance, increasing torque under certain conditions. However, their effectiveness in protecting against contaminants makes them a major asset for use in damp or dusty environments.
