Fafnir RAS and TAS pillow blocks are similar in design and equal in load carrying capacity to the RAK and TAK types, but have slightly different base to center height dimensions to make them interchangeable with certain other competitive designs.
The RAS pillow block is equipped with G-KRRB (R-Seal) wide inner ring bearings, TAS with G-KPPB (Tri-Ply Seal), and the LAS with the G-KLLB (Standard) wide inner ring bearings. Self-locking collars are supplied with all units.
