Deep groove ball bearing SKF 6313-2RS1/C3W64, Outer diameter: 140 mm | Width: 33 mm | Inner diameter: 65 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 deep groove ball bearing is designed to meet the demands of industrial environments requiring reliability and durability. Thanks to its robust construction, it can handle radial and axial loads in both directions, offering great versatility. With rubber seals on both sides and increased internal clearance (C3), this bearing is ideal for applications requiring both high speed and low friction.

Features:
This single-row deep groove ball bearing features a sheet steel cage, providing good impact resistance. Its NBR rubber seals form an effective barrier against water and dust, while retaining the lubricant inside for extended performance. Thanks to its C3 radial clearance, it allows for high rotational speeds and ensures good heat dissipation, minimizing the risk of overheating. This design optimizes durability and reliability, particularly in humid or dusty environments. It is filled with Solid Oil. The Solid Oil filling—an oil-saturated polymer designed to occupy nearly all available space—ensures reliable operation in humid environments. Its microporous structure retains the oil through surface tension, slowly releasing it upon contact with internal surfaces. This ensures constant micro-lubrication, thereby improving the bearing’s overall performance.

Maintenance:
Designed to minimize maintenance requirements, this bearing is sealed and retains the lubricant. However, regular monitoring of temperatures and vibrations is recommended to prevent potential malfunctions. Periodic inspections for noise and temperature help detect early signs of malfunction, ensuring optimal performance and an extended service life. Solid Oil also reduces maintenance requirements by protecting against external contaminants and helping to retain lubricant inside the bearing.

Sealing:
Equipped with nitrile-butadiene rubber (NBR) seals on both sides, this bearing offers excellent protection against external contaminants. The nitrile-butadiene rubber lip seals provide optimal protection against water and dust, thereby preventing lubricant contamination. This barrier helps maintain high performance, even in humid conditions. However, it should be noted that this sealing mechanism may create slight resistance to movement. The close contact between the Solid Oil, the rolling elements, and the rings forms an effective barrier against the intrusion of contaminants, thereby enhancing the bearing’s protection. In addition to limiting the entry of particles, the Solid Oil provides additional support to the integrated seals, improving their durability and ensuring reliable, long-lasting performance, even in harsh environments.

Brand Information:
SKF, founded in 1907 in Sweden, is a global leader in bearings and industrial lubrication. Operating in more than 40 industries, the company is distinguished by its expertise and commitment to quality.
