Deep Groove Ball Bearings FAG 16003 -2Z

Two cover plates made of sheet steel, fitted on both sides, protect the rolling element set against the ingress of dust and foreign particles. As the plates fit against the inner ring without coming into contact with it, they prevent friction losses and are suitable for applications requiring low heat generation and smooth running.

With bearing clearance class CN, the bearing has the radial clearance between the rolling elements and raceways, as defined by the manufacturer, when new. It is designed for standard fits and uniform temperature distribution between the shaft and housing. It therefore ensures smooth running under normal operating conditions without excessive preload or play.

The permissible operating temperature range is from -30 to +120 degrees Celsius. The materials used – the sheet steel cage and the non-contact cover discs – are designed for this temperature range. In the event of extreme thermal conditions, it should be checked in advance whether the thermal expansion of the connecting components requires a different bearing clearance.

The inner ring, outer ring and rolling elements are made from case-hardened standard roller bearing steel of the 100Cr6 grade. This material is characterised by high strength, dimensional stability and fatigue resistance under rolling loads. In industrial operation, it requires proper lubrication to protect the running surfaces from premature wear and corrosive environmental influences.

Inside the bearing, a dimensionally stable cage made of pressed sheet steel keeps the balls at a uniform distance apart. A sheet metal cage keeps moving masses to a minimum and withstands the usual impact and acceleration forces during continuous operation. Furthermore, the open cage design allows sufficient space for the distribution of grease in the area of the ball raceways.
