The FAG 7217 -B-MP angular contact ball bearing, measuring 85 x 150 x 28 mm and with a contact angle of 40 degrees, provides robust support for combined radial and axial loads.
The 7217 -B-MP angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) with a standard radial clearance. Thanks to its modified internal design and a contact angle of 40 degrees, this version can accommodate high axial forces on one side in conjunction with radial forces. Designed as an open bearing, the construction allows for a free supply of lubricant from the bearing environment. The solid brass cage guides the rolling elements precisely and is suitable for demanding operating temperatures ranging from –20 to +150 degrees Celsius.
This design is primarily used where both radial guidance and unilateral axial support forces are present simultaneously. This applies to rotating shafts where there is a defined axial load direction. As a single angular contact ball bearing can only support axial forces in one direction, it is usually fitted in a pair, with one bearing positioned at an angle to the other. This creates a rigid bearing arrangement with precise shaft guidance.
The designation ‘MP’ stands for a solid brass cage. Brass is a material that offers high strength and favourable friction coefficients relative to steel rolling elements, whilst retaining its dimensional stability even under vibration. In combination with the standard tolerance class P0/PN (corresponding to ABEC 1) and the flangeless cylindrical outer ring, the bearing can be fitted precisely into standardised housing bores.
With a bore of 85 mm, an outer diameter of 150 mm and a width of 28 mm, this roller bearing has defined standard dimensions. The bearing has a single-row design, features a cylindrical outer ring without a flange and complies with the P0 or ABEC 1 tolerance class.
The contact angle describes the line along which the rolling elements transmit the contact forces between the raceways. A contact angle of 40 degrees, indicated by the suffix ‘B’, gives the bearing an increased axial load-carrying capacity in one load direction compared with bearings with smaller contact angles.
The open design has no integrated sealing washers. As a result, the lubricant – such as oil or grease – from the gearbox housing circulates unhindered within the bearing chamber. The design must incorporate an external seal for the housing to prevent the ingress of dirt particles and moisture.
The permissible operating range is from -20 to +150 degrees Celsius. Both the 100Cr6 roller bearing steel and the solid brass cage are designed for this range. The thermal stability of the externally supplied lubricant is also crucial for safe operation.
On delivery, this type of bearing has a standard radial bearing clearance. However, in the case of single-row angular contact ball bearings, the actual operating clearance or the desired preload is only established during installation through axial alignment with a second mating bearing. The adjustment is carried out via the housing or shaft fit.
