Thin section Tapered roller bearings 32004 are separate bearings. inner diameter is 20mm, outer dimater is 42mm,width is 15mm.
Tapered roller bearings refer to radial thrust rolling bearings in which the rolling elements are tapered rollers. There are two kinds of small cone angle and large cone angle. The small cone angle mainly bears the combined radial and axial loads mainly with radial loads. It is often used in pairs and installed in reverse. The inner and outer races can be installed separately. The radial and axial clearance can be adjusted during installation and use; The large cone angle mainly bears the axial and radial combined loads, which are mainly axial loads. Generally, it is not used alone to support pure axial loads. When configured in pairs (installed with the same name opposite), it can bear pure radial loads.
The basic dimensions of FQN tapered roller bearings are listed in the dimensional data sheet,
Single-row tapered roller bearings:
Inner diameter size range: 20mm ～ 1270mm
Outer diameter range: 40mm ～ 1465mm
Width size range: 15mm ～ 240mm
Double-row tapered roller bearings:
Inner diameter size range: 38mm ～ 1560mm
Outer diameter range: 70mm ～ 1800mm
Width size range: 50mm ～ 460mm
