Angular Contact Ball B. FAG 7220 -B-XL-TVP-UA
The FAG 7220 -B-XL-TVP-UA angular contact ball bearing accommodates combined loads with a 100 mm bore, 180 mm outside diameter and 34 mm width.
The 7220 -B-XL-TVP-UA angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) for demanding industrial applications. Thanks to its contact angle of 40 degrees, the bearing accommodates high axial forces in one direction as well as simultaneously acting radial forces. The open bearing, which has no seal, allows for direct integration into existing lubrication circuits. Design engineers and maintenance personnel rely on this FAG roller bearing design when precise shaft guidance and defined running characteristics are required.
What is the 7220 -B-XL-TVP-UA angular contact ball bearing suitable for?
This single-row bearing is used in machinery and drives where unidirectional axial loads predominate or occur in conjunction with radial forces. Such units often operate in pairs in gearboxes, pumps or compressors. The suffix ‘UA’ indicates universal suitability for installation in pairs: in an O or X arrangement, the bearing pair has minimal axial clearance. For demanding operating conditions, the integrated polyamide cage covers a temperature range from –20 to +120 degrees.
What role do the contact angle and pairing play in bearing selection?
The contact angle of 40 degrees significantly determines the axial load-carrying capacity of the design. The steeper this angle, the higher the axial forces the bearing can dissipate via the ball row into the outer ring without a flange. When designing, ensure the correct counter-support is provided, as a single angular contact ball bearing can only accommodate axial forces in one direction. Manufacture to tolerance class P0/PN (ABEC 1) provides standardised mounting dimensions for the shaft and housing.
What are the key features of the 7220 -B-XL-TVP-UA angular contact ball bearing?
A single-row angular contact ball bearing of the 72 series with a 100 mm bore, 180 mm outer diameter and 34 mm width. The design features a contact angle of 40 degrees for high axial loads in one direction. Manufactured from 100Cr6 rolling-element bearing steel, the open version with a polyamide cage operates at temperatures ranging from -20 to +120 degrees.
What does the suffix ‘UA’ mean in relation to this bearing?
The designation ‘UA’ stands for a universal design intended for installation in pairs. When two of these bearings are fitted in an O or X configuration, the bearing set already has a pre-set, minimal axial clearance. This simplifies assembly in the workshop or in mass production, as it eliminates the need for time-consuming manual adjustment of the bearing clearance.
What is the temperature range for which the bearing is designed?
The roller bearing is specified for use at operating temperatures between -20 and +120 degrees. The polyamide cage fitted is the key factor determining this range. When selecting a lubricant, you should ensure that it is also suitable for this temperature range.
Why does this angular contact ball bearing not have any sealing washers?
As an open bearing, the component has no integrated seals. This allows lubrication via external oil or grease circuits within the unit. At the same time, the absence of abrasive sealing lips results in low frictional torque during operation. The surrounding housing structure provides protection against dirt particles.
What is the tolerance class of the 7220 angular contact ball bearing?
This bearing is manufactured to the standard tolerance class P0/PN, which corresponds to the ABEC 1 classification. This standard defines standardised dimensional limits and concentricity tolerances for the 100 mm bore and the 180 mm outer diameter, suitable for standard industrial bearing seats.
How does a contact angle of 40 degrees affect load-bearing capacity?
The contact angle describes the inclination of the line of action between the rolling elements and the raceways relative to the radial plane. At an angle of 40 degrees, the bearing is primarily designed to withstand high axial forces. It supports the shaft against unilateral axial thrust but requires a suitable mating bearing to counteract the resulting forces.
