The SKF 22217 E self-aligning roller bearing (85x150x36 mm) withstands heavy radial loads and compensates for misalignment with angular movement whilst in operation.
The 22217 E self-aligning roller bearing is a double-row roller bearing from the SKF Explorer series with a bore diameter of 85 mm, an outer diameter of 150 mm and a width of 36 mm. It compensates for misalignment between the shaft and housing with angular movement. Manufactured from standard 100Cr6 rolling bearing steel and featuring a dimensionally stable sheet steel cage, this rolling bearing is designed for operating temperatures ranging from –30 to +200 degrees. The open bearing is suitable for machine components where high radial forces and axial guidance forces acting in both directions are exerted on the bearing seat.
This self-aligning roller bearing is primarily used in industrial drives and heavy-duty gearbox assemblies where shaft deflection or misalignment occurs. The barrel-shaped rollers and the hollow-spherical outer ring raceway allow the rolling elements to self-align freely. As a result, the component distributes heavy radial and axial loads evenly without generating disruptive edge stresses. Furthermore, the design with standard radial clearance ensures low-vibration operation at typical operating temperatures.
The outer ring is fitted with a lubrication groove and lubrication holes. This feature facilitates the supply of grease or lubricating oil directly into the centre of the rolling elements, enabling you to carry out relubrication during operation in a systematic manner. The increased running accuracy of tolerance class P5, combined with standard dimensional accuracy PN, results in particularly smooth concentricity. When designing the application, please note that the open bearing requires a housing seal to be fitted on site to prevent the ingress of dirt particles.
With a bore diameter of 85 mm, an outside diameter of 150 mm and a width of 36 mm, the bearing complies with the standard metric dimensions for this series. Thanks to these dimensions, the component fits into standardised housing bores and accommodates shafts with a matching fit diameter.
Fresh lubricant is fed directly between the rows of rollers via the circumferential groove and the integrated bores in the outer ring. This design feature ensures even distribution of lubricant within the bearing. Maintenance work and relubrication whilst the bearing is installed can thus be carried out precisely via the appropriate housing connections.
This model features standard radial bearing clearance. The internal bearing clearance falls within the standard range specified for this design. This version is intended for operating conditions characterised by normal heating and standard press fits, ensuring reliable concentricity without thermal distortion once fitted.
The Explorer version is based on an optimised internal geometry and a tempered surface finish on the raceways and rolling elements. These design features contribute to an even distribution of stress and minimise the effects of friction during operation. Combined with P5 running accuracy, this results in low-vibration operation and high load-carrying capacity.
The permissible operating temperature range is from -30 to +200 degrees Celsius. The integrated sheet steel cage and the standard 100Cr6 rolling bearing steel retain their dimensional stability within this temperature range. For operation at the temperature limits, it is necessary to select a lubricant for the housing system that is suitable for these temperatures.
As an open bearing, this design has been deliberately constructed without integrated sealing washers. This allows the bearing to be operated flexibly with either grease or oil. In such installations, protection against dirt, moisture and lubricant loss is provided by external sealing systems in the surrounding bearing housing.
