Deep groove ball bearing SKF 6306-2RS2/C3VT312, Outer diameter: 72 mm | Width: 19 mm | Inner diameter: 30 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 rigid ball bearing is designed to operate at high speeds while maintaining low friction thanks to its increased internal clearance (C3). It effectively supports radial and axial loads in both directions and is easy to install. Thanks to its nitrile-butadiene rubber (NBR) lip seals on both sides, it offers reliable protection against contaminants such as dust, water, and debris.

Features:
This bearing features a robust and reliable sheet steel cage that offers good resistance to constant loads while withstanding shocks and momentary loads. The rubber lip seals on both sides ensure effective sealing against contaminants, while the increased internal radial clearance (C3) helps reduce internal friction. This bearing can handle heavy radial loads while accommodating moderate axial loads, all with smooth and quiet operation. It is also pre-lubricated for life with VT312 lubricant.

Maintenance:
This deep-groove ball bearing is designed to minimize maintenance requirements thanks to its two rubber seals, which effectively retain the lubricant while preventing the intrusion of contaminants. Although maintenance is minimal, it is recommended to periodically check the operating temperature and vibrations to detect any signs of early malfunction. Regular inspections of noise and temperature are essential to ensure a long service life and optimal performance.

Sealing:
This bearing is equipped with nitrile-butadiene rubber (NBR) lip seals on both sides, providing excellent protection against contaminants such as dust and water. These seals ensure that the lubricant remains inside the bearing while preventing the intrusion of foreign particles. The resistance of NBR rubber to oils and greases provides long-lasting protection, even in wet or dusty environments, thereby extending the bearing’s service life.
