Angular Contact Ball B. FAG 7217 -B-XL-TVP-UO
The FAG 7217 -B-XL-TVP-UO angular contact ball bearing, with dimensions of 85 × 150 × 28 mm, is designed as a universal version for play-free bearing pairs under combined loads.
The single-row angular contact ball bearing 7217 -B-XL-TVP-UO from FAG accommodates combined loads from the radial and single-direction axial directions. Manufactured from standard rolling-element bearing steel (100Cr6), this open bearing has a contact angle of 40 degrees. The open design without integrated sealing discs allows for direct lubrication via the surrounding system, whilst the integrated polyamide cage ensures low-noise guidance of the rolling elements during operation.
What is the 7217 -B-XL-TVP-UO angular contact ball bearing suitable for in operation?
This rolling bearing is used where shafts need to be guided whilst simultaneously absorbing unilateral axial forces. Typical applications include high-speed bearing arrangements and general mechanical engineering. Thanks to its contact angle of 40 degrees, the component absorbs axial forces. In combination with a second bearing, mutual misalignment can also be accommodated.
What is the significance of the suffix ‘UO’ when mounting in pairs?
The UO designation identifies this model as a universal bearing. When two bearings are fitted in pairs in an O or X arrangement, the bearing set is adjusted to be play-free once installed. This eliminates the need for additional shims to adjust the axial clearance. Please note the permissible temperature range of -20 to +120 degrees, as well as the requirement for external sealing to prevent the ingress of contaminants.
What are the main dimensions of the 7217 -B-XL-TVP-UO angular contact ball bearing?
The bearing has an inner diameter of 85 mm, an outer diameter of 150 mm and a width of 28 mm. These dimensions allow it to be fitted onto suitable shaft seats and into compatible bearing housings without any modifications to the surrounding structure.
What does the suffix ‘TVP’ mean in relation to this roller bearing?
The suffix ‘TVP’ stands for a polyamide cage. This material is characterised by its low weight and damping properties. As a result, the roller bearing runs quietly and is suitable for dynamic operating conditions.
What is the purpose of the 40-degree pressure angle?
A contact angle of 40 degrees ensures that the line of action of the forces runs at an angle to the radial plane. As a result, the component can accommodate not only radial forces but also high axial loads in one direction. For alternating axial loads, a paired arrangement with a mating bearing is required.
Within what temperature range can the component be operated?
The bearing is designed for an operating temperature range of between -20 and +120 degrees. In addition to the rolling bearing steel, these limits are primarily determined by the integrated polyamide cage and the lubricant. You should always take these temperature limits into account when selecting the lubricant.
Why does this angular contact ball bearing not have an integrated seal?
Designed as an open bearing, this model does not feature any sealing or cover plates. This design reduces frictional resistance and allows lubricating oil or grease to circulate freely. To prevent the ingress of dirt particles, an external seal must be fitted to the machine housing.
