Description

RKB double row angular contact ball bearings can be considered in design similar to a pair of single row angular contact ball bearings in O or X configuration. They can accommodate thrust loads as well as high radial loads. These bearings are normally used in arrangements requiring a rigid axial guidance and they can also withstand tilting moments. Type DBA Double row ACBB back-to-back arrangement (DB) Filling slot on inner ring Non-separable open design Moulded glass fiber reinforced polyamide snap-in cage guided on balls (TN) Available with lubrication holes in the inner ring Supports high combined loads Type DF Double row ACBB face-to-face arrangement (DF) Separable open design Machined brass cage guided on inner ring (MB) Lubrication grooves and holes in outer rings Supports high combined loads Type DB1 Double row ACBB back-to-back arrangement (DB) Non-separable open design Moulded glass fiber reinforced polyamide snap-in cage guided on balls (TN) Available with lubrication holes in the inner ring Supports high combined loads Type DB/ZZ Double row ACBB back-to-back arrangement (DB) Non-separable shielded design (ZZ) Moulded glass fiber reinforced polyamide snap-in cage guided on balls (TN) Available with lubrication holes in the inner ring Shielded type to keep the grease inside the bearing without compromising the limiting speed Supports high combined loads
