Decoding FAG 7328-B-MP
- 73Series
- Angular contact ball bearings, 73 series. Series differ in outside diameter and width even when the bore is the same.
- 28Bore
- Bore 140 mm (28 × 5).
- B-MPSuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7328 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 7328-B-MP measures 140 mm across the bore and 300 mm across the outside diameter; its width is 62 mm (140 x 300 x 62 mm).
FAG 7328-B-MP belongs to angular contact ball bearing, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 7328-B-MP and any equivalents.
When a shaft carries both radial and axial forces, FAG angular contact ball bearings are a common choice. Their offset raceways let them take thrust in one direction, so they typically work in pairs to handle combined loads and add rigidity. We supply the FAG line for equipment where axial capacity and precision matter.
The part number tells you what you are holding. Take 7232-B-MP: the first block gives size and dimensional series, the B sets the contact angle, and MP indicates a machined brass cage. The same pattern applies to 7330-B-MP. Always send the complete designation when requesting a quote so the exact variant is identified.
You will find these bearings in centrifugal pumps, screw compressors, gear reducer boxes, machine tool spindles, and transmission equipment where axial load is significant. They also appear in process plants, food production, cement operations, and maintenance workshops that service critical machinery. A single support that manages radial and axial forces together is what makes them useful on demanding shafts.
Selection starts with the direction of the axial load. Because these bearings accept thrust in only one direction, they are almost always installed face-to-face or as matched pairs. Internal clearance and preload are set according to the application; for spindles and precision equipment, define preload before mounting. Lubrication and sealing follow the environment: grease for low speed or oil where heat needs to be dissipated. Keeping the supports aligned prevents overloading the cage.
Do not cross-reference part numbers by similarity. Each manufacturer uses its own codes for contact angles and cages, so compare main dimensions, load capacity, and cage type against the original designation. If the bearing is factory-matched, replace the pair as a unit. When in doubt, provide the old part number plus shaft and housing measurements.

Frequently asked questions
- FAG 7328-B-MP bearing: what are its dimensions?
- FAG 7328-B-MP measures 140 mm across the bore and 300 mm across the outside diameter; its width is 62 mm (140 x 300 x 62 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7328.
- What do the B and MP suffixes mean on these bearings?
- The B indicates the contact angle of the series, which determines how axial load is distributed. MP refers to a machined brass cage designed for high demands. Both are part of the designation and should be included when requesting a quote.
- Can they be mounted individually or are they always in pairs?
- Since they absorb axial load in a single direction, they are usually mounted face-to-face or as matched pairs. This arrangement covers thrust in both directions and increases rigidity. Individual mounting depends on the support calculation.
- How do I request a quote for an FAG bearing from this series?
- Send the complete part number from the bearing or equipment manual via WhatsApp or email, along with the main measurements if available. We will identify the variant and reply promptly.
