Deep groove ball bearing SKF 6004-2Z/LHT23, Outer diameter: 42 mm | Width: 12 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.

SKF offers this deep-groove ball bearing with metal flanges, designed to provide a good balance between load capacity, efficiency, and moderate protection against contaminants. This bearing is suitable for a wide range of industrial applications and is distinguished by its robustness, ability to operate at high speeds, and low friction. It is particularly well-suited for environments where protection against large debris and medium-sized particles is required.

Features:
This SKF single-row deep groove ball bearing features excellent radial load capacity and moderate axial load capacity, thanks to its sheet steel cage. The standard radial clearance (CN) reduces friction, ensuring smooth operation even at high speeds. The metal flanges add a slight amount of additional friction but act as a barrier against large contaminants. As a result, this bearing offers a perfect balance between protection against debris and moderate friction, with controlled noise and vibration levels. In addition, it is lubricated with a lithium-thickened grease, NLGI Class 2, allowing it to operate in a temperature range from -50 to +140 °C.

Maintenance:
This deep-groove ball bearing, equipped with metal shields on both sides, provides effective protection against medium- and large-sized contaminants thanks to its narrow-gap seal. Pre-lubricated with high-quality grease, it is designed for operation without relubrication, thereby reducing maintenance costs and downtime. Its standard clearance (CN) ensures stable performance while requiring only moderate maintenance. However, it is advisable to conduct regular inspections to assess the bearing’s condition (noise, temperature, integrity) and to clean the outer surfaces as needed to remove dust or debris. If signs of wear or failure are detected, prompt replacement is recommended to prevent further damage to the equipment.

Sealing:
This bearing is equipped with metal shields that provide protection against the ingress of large debris and more limited protection against dust and medium-sized particles.
These shields also help keep the lubricant inside, thereby preventing leakage.
