Deep groove ball bearing SKF 6218-2Z/VA228, Outer diameter: 160 mm | Width: 30 mm | Inner diameter: 90 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-brand deep groove ball bearing is specially designed for very high-temperature applications (+350°C), offering optimal reliability and efficiency under demanding operating conditions. Equipped with two metal shields, this bearing provides effective protection against contaminants while reducing maintenance requirements. Its robust design and lifetime lubrication guarantee optimal performance while minimizing downtime and maintenance costs.

Features:
This bearing is designed to operate at very high temperatures. Featuring a graphite segmented cage and two metal shields, it is effectively protected against solid contaminants. Its components—cage, rings, and rolling elements—are manganese-phosphated to improve lubricant adhesion and facilitate running-in. Lubricated for life with a high-temperature graphite-based lubricant, it can operate trouble-free up to +350 °C. Designed to withstand harsh conditions, this bearing features a radial clearance of C5, which is ideal for preventing seizure and dimensional changes in materials caused by temperature fluctuations, particularly during rapid cooling.

Maintenance:
This bearing is virtually maintenance-free thanks to its lifetime lubrication with high-quality grease. No relubrication is necessary, which minimizes maintenance costs and production downtime. However, periodic inspections are recommended to check its condition, particularly by monitoring noise, which can be a sign of misalignment. In the event of a suspected failure, prompt replacement is advised.

Sealing:
The bearing is equipped with two metal shields, providing an effective barrier against medium-sized solid contaminants. These sheet steel shields limit the intrusion of debris while reducing lubricant loss. The narrow gap between the flanges and the internal components ensures effective protection while minimizing friction.
