Deep groove ball bearing SKF 6211-2Z/C4VT127C, Outer diameter: 100 mm | Width: 21 mm | Inner diameter: 55 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 deep-groove ball bearing, featuring a significantly increased radial clearance (C4), protective steel sheet flanges, and a high-temperature lubricant, is designed to deliver excellent performance at high speeds. Its design ensures effective protection against contaminants while providing minimal internal friction and optimal resistance to demanding operating conditions.

Features:
This single-row deep groove ball bearing from SKF is distinguished by its two sheet steel shields, which provide effective sealing against medium-sized particles. The significantly increased radial clearance (C4) further reduces internal friction, enabling smooth operation at extremely high speeds without the risk of performance loss due to steel expansion. It can withstand heavy radial loads as well as moderate axial loads in both directions, offering exceptional versatility. Lubricated for life with high-performance grease, it operates effectively over a temperature range from -35 °C to 260 °C. The sheet steel cage enhances its ability to withstand shocks and momentary loads.

Maintenance:
This bearing is designed to minimize maintenance requirements, as it is permanently lubricated with high-quality grease and protected by metal flanges. The significantly increased radial clearance (C4) minimizes internal friction as much as possible, thereby limiting the need for intervention. However, regular inspections are recommended to monitor the bearing’s condition by checking for abnormal noise, temperature, and the integrity of the flanges. If signs of wear appear, prompt replacement is recommended to prevent potential failure.

Sealing:
The bearing is equipped with two steel sheet metal flanges, ensuring effective sealing against contaminants such as debris and fibers. This narrow-gap seal minimizes lubricant loss, ensuring constant protection of the internal components. Although effective against most particles, this protection may be limited in the event of prolonged exposure to moisture or liquid splashes.
