Tapered Roller Bearings
Double row tapered roller bearings consist of two mirror-image arranged side by side tapered rolling element rows. Depending on arrangement, they share an inner or outer ring and are adjusted for axial clearance or pre-stress with a spacer ring. This way, they can in addition to radial forces also absorb axial forces in both directions and are suitable for medium to high speeds. Double row tapered roller bearings can be disassembled which facilitates a separate assembly of the individual bearing rings.
Absorption of high axial and radial forces
Pre-set axial clearance or preload
Available in X- or O-arrangement
Dimensions and Tolerances
The boundary dimensions of the bearings are not standardized. ALPHA Wälzlager GmbH supplies double row tapered roller bearings with normal tolerance (PN) in accordance to DIN 620-2 and ISO 492. Please contact our technical department to check the availability of bearings with improved accuracy class or special tolerances.
Bearing Clearance or Preload
The bearing clearance or preload is chosen by the customer and application and is adjusted by a spacer ring.
