Deep groove ball bearing SKF 6203-2RSL/W64, 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 SKF brand deep groove ball bearing provides robust support for radial and axial loads in both directions, while standing out for its ease of installation. Designed to operate in demanding environments, this product is equipped with rubber seals for optimal protection against contaminants, ensuring reliable performance and a long service life. Suitable for a wide range of applications, this bearing is ideal for industrial, agricultural, and automotive uses where reliability and low maintenance are essential.

Features:
Featuring a sheet steel cage, this single-row ball bearing provides good resistance to heavy radial loads and moderate axial loads. Its low-friction nitrile rubber (NBR) lip seals on both sides provide effective sealing, preventing the ingress of dust, water, and particles. The standard internal clearance of this bearing ensures stability and precision when used in mechanical systems. This model features a Solid Oil filling, an oil-impregnated polymer that occupies virtually all available space. This design ensures efficient operation, even in humid environments. The microporous structure of Solid Oil retains the oil through surface tension and gradually releases it upon contact with internal surfaces, thereby ensuring continuous, low-intensity lubrication. This optimizes the bearing’s performance, making it an ideal choice for systems requiring efficient cooling.

Maintenance:
This deep-groove ball bearing requires little maintenance, thanks to its rubber seals that effectively retain the lubricant inside. The RSL seals developed by SKF feature an optimized design to minimize friction losses while ensuring a long-lasting seal. This innovation effectively keeps the lubricant inside the bearing, preventing the entry of moisture or contaminants, even in highly corrosive or contaminated environments. Solid Oil also reduces maintenance requirements by providing a barrier against external contaminants and effectively retaining the lubricant inside. The finite element-optimized design of the RSL seals minimizes friction losses, thereby improving high-speed performance and extending service life.

Sealing:
This rigid bearing is equipped with nitrile-butadiene rubber (NBR) seals on both sides, ensuring effective sealing. NBR rubber forms a barrier against particles, moisture, and other contaminants, while being resistant to oils and greases. These seals extend the product’s service life by reducing the ingress of debris, thereby ensuring reliable performance even in dusty or humid environments. Solid Oil not only limits particle ingress but also enhances the effectiveness of the integrated seals, increasing their durability and ensuring reliable, long-lasting performance even under demanding conditions.
