Decoding FAG 21307-E1-XL-K-TVPB
- 213Series
- Spherical roller bearings, 213 series. Series differ in outside diameter and width even when the bore is the same.
- 07Bore
- Bore 35 mm (07 × 5).
- E1-XL-K-TVPBSuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
21307 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 21307-E1-XL-K-TVPB measures 35 mm across the bore and 80 mm across the outside diameter; its width is 21 mm (35 x 80 x 21 mm).

When shafts flex or housings are not perfectly aligned, spherical roller bearings handle combined radial and axial loads while compensating for misalignment. The FAG E1 XL K TVPB execution is available from MR Industrial Accessories LLC, a Miami-based supplier serving customers across the United States and Latin America. These bearings are selected by part number to match the required size and bore type for each application.
The part number breaks down into distinct blocks. The first digits indicate the series and size: 21307, 21319 and 21320 belong to the 213 series, while 23022, 23024 and 23028 are in the 230 series. The E1 suffix denotes an execution with optimized rollers and cage; XL indicates improved load capacity; K means a tapered bore; and TVPB refers to a roller-guided window polyamide cage. Reading these blocks lets you pinpoint the exact variant.
In industrial settings, these bearings are found in belt conveyors, gearboxes, mills, screens, mixers and process equipment where shaft deflection or imperfect seat alignment occurs. They also appear in road machinery, material handling equipment and aggregate plants. Their ability to compensate for misalignment suits them to long shafts or structures subject to vibration and variable stresses.
Selection starts with the shaft diameter and bore type. The K variant has a tapered bore and is mounted with an adapter sleeve or directly on a tapered shaft, which simplifies adjusting internal clearance. Define the sealing based on the environment: dust, water or retained lubricant. During mounting, check initial alignment, radial clearance and lubrication; proper grease or oil charge and a clean seat help extend bearing life. If the equipment operates with permanent misalignment, the spherical design absorbs it, but verify it does not exceed design limits.
Interchangeability between brands is resolved by dimensions and execution type: a spherical roller bearing with tapered bore and polymer cage can be replaced by another with the same dimensional designation, verifying tolerances and clearance. Suffix letters vary by manufacturer, so equivalence is confirmed with the complete part number and dimensions. If you have the old part number or equipment drawing, send it and it will be compared against the available designation.

Frequently asked questions
- FAG 21307-E1-XL-K-TVPB bearing: what are its dimensions?
- FAG 21307-E1-XL-K-TVPB measures 35 mm across the bore and 80 mm across the outside diameter; its width is 21 mm (35 x 80 x 21 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 21307.
- What does the K suffix mean in the designation?
- The K indicates a tapered bore. This type is mounted with an adapter sleeve or on a tapered shaft, allowing radial clearance to be adjusted during mounting. It is common where shaft tolerances need compensation or disassembly must be easier.
- How do I request a quote for a bearing of this series?
- Send the complete part number by WhatsApp or email, for example 23024-E1-XL-K-TVPB, or the equipment model. The series, size and suffix are identified, and we reply promptly with the corresponding reference.
- Can it be replaced by another brand?
- Yes, if dimensions and execution type match. Interchangeability is verified with the complete part number and dimensions, as suffixes change between manufacturers. Send the original part number and it will be compared with the equivalent designation.
