Alignment Needle Roller Bearings
AMIGO Alignment needle roller bearings feature an outer ring with a convex surface. Two polymer seating rings with a concave surface are housed in a drawn sheet steel sleeve and fit over the outer ring.
- Accommodate static misalignment
Alignment needle roller bearings are self-aligning up to 3° of static misalignment. - Low cross section
In applications where less space is available, alignment needle roller bearings offer a compact solution. - High carrying capacity
Owing to their large number of rollers, alignment needle roller bearings have a high load carrying capacity.
AMIGO Alignment needle roller bearings with machined rings are widely used in various industries. Their availability matches their versatility across numerous applications in a wide range of designs, variants, and sizes. Examples of applications include:
- Automotive Industry
- Construction Machinery
- Agricultural Equipment
- Aerospace Industry
- Textile Machinery

Alignment Needle Roller Bearings - Designs and Variants
Bearings with an Inner Ring
Bearings with an inner ring are suitable for applications where the shaft cannot be hardened or ground. They allow limited axial displacement of the shaft relative to the housing, which can be extended using a wide inner ring if necessary.
Bearings without an Inner Ring
Bearings without an inner ring are an excellent choice for compact bearing arrangements where the shaft can be hardened and ground. This option is ideal for setups requiring a larger shaft diameter and stiffer bearing arrangement compared to those with inner rings.
