Product Details

 SKF supplies track roller bearings greased, sealed and ready-to-mount. They are available in many different types and designs and for a wide variety of operating conditions and applications. The assortment includes:

  • cam roller bearings (yoke-type track roller bearings based on ball bearings)

  • support roller bearings (yoke-type track roller bearings based on roller bearing bearings)

  • cam followers (stud-type track roller bearings based on roller bearing bearings)

SKF 305805 C-2Z Cam roller bearings are ball bearings which have a particularly thick-walled outer ring.They are ready-to-mount pre-greased units and are used for all types of cam drives, conveyor systems etc.

Single Row SKF 305805 C-2Z Cam roller bearings are based on deep groove ball bearings in the 62 series. They are supplied greased and are seals both sides with a reinforced NBR contact seal and have a crowned outer race.

SKF 305805 C-2Z Double Row Cam roller bearings are based on double row angular contact ball bearings in the 32 dimension series and have a 30 degree contact angle. They are supplied greased and are fitted with metal shields both sides which extend into a recess on the inner ring.  

The SKF 305805 C-2Z series with a crowned runner surface should always be used where angular misalignments with respect to the track may be expected and edge stress should be kept to a minimum.These wide cam roller bearings have been developed with a 30° contact angle.They are fitted with sheet steel shields which extend into recesses in the inner ring side to keep the lubricant in and contamination out.

SKF SKF 305805 C-2Z Double Row Cam roller bearings: Are special variants of deep groove ball bearings which have thicker outer races to allow for running in tracks as roller bearings where misalignment and shock loads may be present. They have the same characteristics as normal deep groove ball bearings, generally have seals although some unsealed versions are available and can also be used in place of standard bearings.  

SKF 305805 C-2Zcam rollers (yoke-type track roller bearings based on ball bearings) bearings are available in two main designs and also as variants of these:single row cam roller bearings based on deep groove ball bearingsand  double row cam roller bearings based on double row angular contact ball bearings.

 

SKF 305805 C-2Z Cam roller bearing features

Accommodate high radial loads 
The thick-walled outer ring enables high radial loads, while reducing distortion and bending stresses.

Accommodate tilting moments 
Double row cam roller bearings accommodate higher tilting moments than single row cam roller bearings.

Long service life 
The crowned outer ring running surface is beneficial for applications where outer ring tilting  elative to the track may occur or where edge stresses need to be minimized.

Relatively high speed capability
