Slewing Bearings have high load carrying capacity, a versatile range of applications and are highly 

costeffective.Due to their design, a single bearing can reliably support radial,axial and tilting moment

 loads. It is therefore possible in many cases to replace bearing arrangements comprising a 

combination of radial and axial bearings by a single bearing. BYC Slewing Bearings have Two types:

Four point contact slewing bearings and crossed roller slewing bearings.

Four point contact bearing, standard series 20, external gear teeth, selectable internal clearance, 

sealed, lubrication nipple on circumference of ring without teeth
