Deep groove ball bearing SNR 63003EEC3, Outer diameter: 35 mm | Width: 14 mm | Inner diameter: 17 mm

This SNR deep groove ball bearing was specially developed to meet the demands of modern industrial applications. It is particularly suitable for environments exposed to dust, moisture or temperature fluctuations. Thanks to its reinforced sealing and reliable performance, it provides optimal protection and a long service life.

Features:
This single-row ball bearing is equipped with a light yet sturdy pressed-steel cage. This ensures precise ball guidance and high durability at high speeds. It features an internal radial clearance of class C3, which helps reduce friction and compensate for thermal expansion at high speeds. Seals on both sides made of NBR rubber (acrylonitrile-butadiene rubber) reliably protect against the ingress of dirt particles. The bearing is especially suitable for applications with high speeds and moderate mechanical loads, without compromising performance.

Maintenance:
This model is factory-lubricated with a high-performance grease that has been applied in a precisely dosed quantity to ensure maximum service life. Thanks to the integrated seals, the lubricant remains enclosed inside the bearing while external contaminants are effectively kept out. The bearing is maintenance-free as long as the operating limits regarding load, speed and temperature are respected. It is therefore particularly suitable for hard-to-reach installation locations where maintenance is limited.

Sealing:
The bearing is fitted on both sides with NBR lip seals that provide excellent protection against dust, splash water and other media. Nitrile rubber offers excellent resistance to oils and greases and forms a durable barrier against external influences. The double-sided sealing creates a constant frictional contact with the inner ring, which increases the frictional torque and limits the maximum permissible speed, while ensuring optimal lubricant protection. This combination of controlled friction and robust sealing makes the bearing a reliable solution in demanding environmental conditions.
