FAG Bearing 20216-K-TVP-C3

Product description of FAG Bearing 20216-K-TVP-C3

FAG Bearing 20216-K-TVP-C3 Barrel roller bearings are single row, self-aligning roller bearings. They comprise an outer ring with a concave raceway, an inner ring with two ribs and a cylindrical or tapered bore as well as barrel rollers with cages.

Barrel roller bearings are suitable for compensating angular misalignment where there is skewing between the outer and inner ring. As a result of the line contact between the rolling elements and raceways, they can support very high radial loads, even if shock type loads occur. In contrast, axial load carrying capacity is low.

Technical information on Barrel roller bearings

Barrel roller bearings are suitable:
for compensating angular misalignment where there is skewing between the outer and inner ring
where high radial shock type loads occur, as a result of the line contact
where angular assignments and high radial loads occur, but speed is not a priority

Fr = radial load
Cr = radial basic dynamic load rating

FAG Bearing 20216-K-TVP-C3Bearings of basic design
The outer ring has a curved raceway Barrel roller bearings are single row, self-retaining radial roller bearings, which are part of the group of self-aligning bearings. The outer ring has a concave raceway. As a result, the bearings permit the compensation of static and dynamic angular misalignment (skewing between the inner and outer ring) within certain limits. The inner ring has a formed raceway for the rolling elements and two rigid ribs. The rollers are barrel-shaped and are guided between the inner ring ribs. Their outside surface line closely follows the raceway profile of the outer and inner ring. Solid cages made from poly-amide PA66 or brass are used.

The bore is cylindrical or tapered Barrel roller bearings of basic design are available with a cylindrical or tapered bore, as a function of the bore diameter d

Compensation of angular misalignment

FAG Bearing 20216-K-TVP-C3, Barrel roller bearings compensate dynamic and static angular misalignment Due to the concave rolling element raceway in the outer ring, barrel roller bearings are capable of angular adjustment. As a result, they permit skewing between the outer and inner ring within certain limits, without causing damage to the bearings, and can thus compensate misalignment, shaft deflections and housing deformations.

Permissible adjustment angle

With a rotating inner ring, barrel roller bearings can swivel up to 4° from their central position The magnitude of alignment and angular defects may only be so large when the bearings are mounted that the contact surfaces of the rolling elements under load still lie within the width of the raceway. Under normal operating conditions and with a rotating inner ring, barrel roller bearings can swivel by up to 4° from their central position. The extent to which this value can be used for skewing between the inner and outer ring is, however, essentially dependent on the design of the bearing arrangement.
