FAG Barrel roller bearings - single row self-aligning roller bearings
8. Dec, 2010 Shandong Obetter bearing Co., Ltd
Barrel roller bearings are single row, self-aligning roller bearings. They comprise solid outer rings with a concave raceway, solid inner rings with two ribs and a cylindrical or tapered bore and barrel rollers with cages. The bearings cannot be dismantled.Barrel roller bearings are particularly suitable where high radial shock type loads occur and misalignments must be compensated, see Compensation of angular misalignments. Their axial load carrying capacity is small.
The barrel roller bearings have special structure. They comprise solid outer rings with a concave raceway, solid inner rings with two ribs and a cylindrical or tapered bore as well as barrel rollers with cages. The bearings cannot be dismantled. Barrel roller bearings are particularly suitable for where high radial shock type loads occur and misalignments. They have only a low axial load carrying capacity.

1.With tapered bore and with adapter sleeve
Bearings with a tapered bore have a bore taper 1:12 and the suffix K.
These bearings are also available with an adapter sleeve for locating purposes. The adapter sleeves are included in the dimension tables and must be specified in addition when ordering.
2.Sealing :Barrel roller bearings are not sealed
3.Lubrication: The bearings can be lubricated from the end faces using oil or grease.
4.Compensation of angular misalignments
Under normal operating conditions and with a rotating inner ring, barrel roller bearings can swivel approx. 4° about their central position. As a result, they permit skewing between the inner and outer ring and can thus compensate misalignments, shaft deflections and housing deformations.
If the outer ring rotates or the inner ring undergoes tumbling motion, the angular adjustment facility is smaller. In this case, please contact us.
5. Operating temperature:
Barrel roller bearings with brass cages can be used at operating temperatures from –30 °C to +150 °C.
Bearing with an outside diameter over 120 mm are dimensionally stable up to +200 °C.
Bearings with cages made from glass fibre reinforced polyamide are suitable for operating temperatures up to +120 °C.
6.Cages
The standard cages for barrel roller bearings are shown in the table link.
Barrel roller bearings with solid brass cages have the suffix MB. The cages are guided on the inner ring.
Solid window cages made from glass fibre reinforced polyamide are indicated by the suffix TVP.
Check the chemical resistance of polyamide to synthetic greases and lubricants with EP additives.
Aged oil and additives in the oil can impair the operating life of plastic cages at high temperatures.
The oil change intervals must be observed
