Deep groove ball bearing SKF W 61905-2RS1/W64, Outer diameter: 37 mm | Width: 7 mm | Inner diameter: 25 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 ball bearing features a robust stainless steel construction, making it corrosion-resistant while supporting both radial and axial loads. Its sealing with nitrile-butadiene rubber seals enhances its durability.

Features:
This deep-groove ball bearing features a single-row design that allows for balanced load distribution. The standard internal radial clearance balances performance between load capacity and friction reduction for general applications. Equipped with rubber lip seals on both sides, it protects against the intrusion of contaminants, thereby extending the product’s service life. The stainless steel cage provides excellent corrosion resistance, which is essential in marine and food-processing applications. The Solid Oil filling—a oil-saturated polymer molded to fill nearly all the free space—ensures reliable operation in humid environments. Its microporous structure retains the oil through surface tension and gradually releases it upon contact with internal surfaces, ensuring continuous micro-lubrication that enhances performance.

Maintenance:
Maintenance of this deep-groove ball bearing is minimal thanks to its seals, which keep the lubricant inside and contaminants out. However, it is recommended to periodically check the bearing’s condition to ensure optimal performance. Solid Oil also helps reduce maintenance requirements by protecting against external contaminants and helping to retain the lubricant inside.

Sealing:
Nitrile-butadiene rubber lip seals provide effective protection against water and dust, thereby preventing any contamination of the lubricant. This barrier helps maintain high performance, even in humid environments. However, it is important to note that this sealing mechanism may introduce slight resistance to movement. The close contact between the Solid Oil, the rolling elements, and the rings creates an effective barrier against the penetration of contaminants, thereby ensuring enhanced protection for the bearing. In addition to limiting the intrusion of particles, the Solid Oil provides additional support to the integrated seals, improving their durability and contributing to reliable and long-lasting bearing performance, even in demanding environments.

• Stable performance: operates at high speeds while maintaining low friction.
• Enhanced protection: rubber seals provide an effective barrier against contaminants.
• Easy installation: it can be easily installed in various systems, making replacement simple.
• Extended service life: when temperatures rise, Solid Oil releases oil to the polymer surface, ensuring optimal lubrication within the bearing.
• Thermal resistance: The polymer reabsorbs the released oil, even under high temperatures.
• Wash resistance: Solid Oil remains intact and cannot be washed away by water.
• Reduced maintenance: The seals and Solid Oil effectively retain the lubricant inside the bearing.

Applications:
This deep-groove ball bearing is particularly well-suited for industries where corrosion resistance is essential. Used in food processing, pharmaceutical, and marine equipment, it is employed in applications requiring protection against moisture and chemicals. Whether in material handling systems, conveyors, or packaging machines, it ensures reliable performance, even under harsh operating conditions.
