Tapered Roller Bearings FAG 32209
The 32209 tapered roller bearing, with dimensions of 45 × 85 × 24.75 mm, accommodates high radial loads as well as unilateral axial loads in demanding industrial applications.
The 32209 tapered roller bearing from FAG Rolling Bearings is designed as a single-row bearing for the specific purpose of accommodating combined radial and axial forces. Thanks to the tapered geometry of the raceways and rollers, the component distributes the forces acting upon it evenly across the contact surfaces. This complete tapered roller bearing is suitable for machinery and gearbox designs where defined guiding forces are required. It operates within a temperature range of -30 to +120 degrees, thereby reliably meeting the typical thermal requirements of industrial operating environments.
What is the 32209 tapered roller bearing suitable for in industrial drives?
The 32209 tapered roller bearing is primarily used in shaft mountings and gearboxes subject to combined loads. Due to their design, single-row tapered roller bearings can only accommodate axial forces from one direction, which is why users often mount these roller bearings in pairs in a staggered arrangement. This allows the bearing assembly to be adjusted to be play-free and stabilises shaft guidance even with varying load directions. The component supports designs where high rigidity and controlled force distribution under dynamic loading are paramount.
What is important regarding tolerance class P0 and the sheet steel cage?
In the design of this bearing, tolerance class P0/PN (corresponding to ABEC 1) defines the standardised dimensional and running tolerances for the industrial standard. The integrated sheet steel cage guides the tapered rollers during operation and withstands mechanical stresses within a temperature range of -30 to +120 degrees. Before fitting, check the mounting dimensions of 45 mm inner diameter and 85 mm outer diameter, as well as the overall width of 24.75 mm, to ensure that the alignment of the bearing rings achieves the required running performance.
What are the dimensions of the 32209 tapered roller bearing?
The bearing has an internal diameter of 45 mm, an external diameter of 85 mm and a total width of 24.75 mm. These standardised dimensions enable it to be fitted precisely into housings and onto shafts designed for these dimensions. When designing, always ensure that these mounting dimensions are adhered to.
What loads can a single-row tapered roller bearing support?
Single-row tapered roller bearings can simultaneously accommodate high radial forces and unidirectional axial forces. Owing to their geometry, the truncated conical rollers produce line contact with the raceway, resulting in high load-carrying capacity. To support axial loads from both directions, two bearings of this type are mounted in a mirror-image configuration.
What does the tolerance class P0/PN mean for this bearing?
The designation P0 or PN stands for the standard tolerance in accordance with international standards and corresponds to the ABEC-1 classification. It defines the permissible deviations in dimensions, shape and running for rings and rollers. This tolerance class meets the requirements of most industrial machinery without the need for special fits for precision spindles.
What is the temperature range for which the 32209 tapered roller bearing is designed?
The bearing is specified for use in temperature ranges from -30 to +120 degrees. This range is determined by the material stability of the bearing components and the sheet steel cage. When designing the lubrication system, care must be taken to ensure that the selected lubricant retains its lubricating properties within these temperature limits.
What is the purpose of the sheet steel cage?
A cage made of pressed sheet steel keeps the tapered rollers at a uniform distance apart and prevents the rolling elements from coming into direct contact with one another. Sheet steel offers high strength combined with low weight and can easily withstand operating temperatures ranging from -30 to +120 degrees. Furthermore, the open cage design allows sufficient space for lubricants within the rolling element chamber.
Can the 32209 tapered roller bearing be fitted separately?
Tapered roller bearings of this design are of a separable construction. The inner ring, together with the roller set and the sheet steel cage, forms a single unit, whilst the flangeless outer ring can be fitted separately. This separate assembly simplifies installation in the housing and on the shaft, as well as the subsequent adjustment of the required bearing clearance.
