Tapered Roller Bearings FAG 33021

The FAG 33021 single-row tapered roller bearing, measuring 105 × 160 × 43 mm, is designed to withstand high combined radial and axial loads in mechanical engineering applications.

The 33021 tapered roller bearing is a separable radial roller bearing in a standard metric design. It accommodates shafts with an internal diameter of 105 mm and supports them in housings with an external diameter of 160 mm. Due to the line contact between the truncated cone-shaped rolling elements and the raceways, the design can withstand high radial loads. The manufacturer, FAG, produces this bearing to standard tolerances.

What loads can the 33021 tapered roller bearing withstand?

Typical applications include bearing arrangements where radial loads and single-sided axial forces occur simultaneously. As a single single-row bearing can only accommodate axial forces from one direction, the component is usually fitted in pairs in combination with a second tapered roller bearing. This arrangement is used for the play-free or specifically preloaded guidance of rotating machine parts.

What is important when installing the bearing with a sheet steel cage?

The open design allows for separate assembly: the outer ring can be fitted independently of the inner ring and the set of rollers, which facilitates installation in tight machine housings. The integrated sheet steel cage guides the rolling elements with minimal vibration and covers a temperature range from -30 to +120 degrees. As an open bearing, the bearing housing requires external sealing as well as lubrication with grease or oil as required.
