Deep groove ball bearing SKF W 638/4-2Z, Outer diameter: 9 mm | Width: 4 mm | Inner diameter: 4 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 ball bearing withstands radial and axial loads in both directions, while offering easy installation. Its stainless steel construction and metal flange sealing system provide effective protection against contaminants.

Features:
This single-row deep groove ball bearing is manufactured with a stainless steel cage, providing excellent corrosion resistance. It is equipped with two metal shields that provide protection against medium-sized particles. Designed with standard internal radial clearance, it offers a perfect balance between performance and efficiency, allowing for high speeds while maintaining moderate friction. This product is ideally suited for applications requiring moderate radial loads and light axial loads.

Maintenance:
Maintenance of this deep groove ball bearing is simplified thanks to its lifetime lubrication with high-quality grease, eliminating the need for relubrication. It is recommended to perform periodic inspections to monitor the bearing’s condition, checking for abnormal noises, temperature, and overall integrity.

Sealing:
This deep groove ball bearing features two metal shields. These shields act as a mechanical barrier that prevents the ingress of debris and contaminants, while causing minimal friction losses. They keep the lubricant inside the bearing.
