Deep groove ball bearing SKF 393921 E, Outer diameter: 40 mm | Width: 12 mm | Inner diameter: 17 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, their ability to operate at high speeds, and their low maintenance requirements.

This double-row angular contact ball bearing is an ideal solution for systems requiring a combination of durability and performance. Designed to simultaneously support radial and axial loads, this product ensures smooth operation and enhanced reliability. Its optimized construction facilitates installation while ensuring long-lasting performance in controlled environments.

Features:
This double-row angular contact ball bearing features a robust sheet steel cage and an open design, allowing for easy access for maintenance and lubrication. Its solid inner and outer rings provide high stability under constant loads. This bearing is designed as two single-row angular contact ball bearings arranged in an O-configuration, but with a reduced width. Double-row angular contact ball bearings can support both radial and axial loads in both directions. An increased contact angle enhances their ability to support axial loads. It features non-standard radial clearance.

Maintenance:
Regular maintenance is essential to ensure optimal service life. The bearing must be lubricated with a suitable product, depending on the operating conditions. Periodic inspections of lubrication, vibrations, and temperature help detect any abnormalities.

Sealing:
This open-design, deep groove ball bearing has no seals, making it more susceptible to contaminant ingress. This design is best suited for clean or low-contamination environments. Although the absence of seals simplifies maintenance and facilitates cooling, it requires regular lubrication and frequent inspections to prevent premature failure.
