Deep groove ball bearing SKF 61904-2RS1/C3HGJN, Outer diameter: 37 mm | Width: 9 mm | Inner diameter: 20 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-brand deep groove ball bearing provides reliable support for radial and axial loads in both directions, delivering optimal performance in demanding environments. Thanks to its rubber seals, it ensures excellent sealing, and its C3 radial clearance increases speed and reduces friction, guaranteeing long-lasting efficiency. Perfect for low-maintenance applications, it is suitable for high-precision equipment with a long service life.

Features:
This single-row SKF bearing is designed with a sheet steel cage that ensures good resistance to constant loads and shocks. Equipped with rubber lip seals on both sides, it is protected against dust and contaminants while retaining the lubricant inside. Its lubrication with polyurea-based grease allows it to operate in temperature ranges from -30 to +150 °C, ensuring reliability under various conditions. The C3 clearance reduces internal friction, making it ideal for high-speed applications where heat dissipation is critical.

Maintenance:
Designed to minimize maintenance requirements, this bearing requires little intervention thanks to its rubber seals that retain the lubricant. However, periodic checks of temperature and vibration are recommended to detect any abnormalities early. It is advisable to monitor for signs of wear or noise to ensure optimal operation and anticipate potential maintenance needs.

Sealing:
The NBR rubber seals, which are resistant to oils and greases, provide robust protection against external contaminants such as dust and water. This type of seal allows the bearing to retain lubricant while preventing the intrusion of particles, thereby increasing the product’s service life, even in humid or dusty environments. Sealing performance is enhanced, minimizing maintenance requirements and extending the equipment’s durability.
