About Berolix
Berolix is an independent, cross-manufacturer bearing data reference. Look up any bearing model and see every major brand's designation, dimensions, load ratings and speed limits side by side — plus what each suffix and variant code actually means. Built for engineers, purchasers and anyone who works with bearings.
Why Berolix
Manufacturers publish only their own catalogs, and distributors list only what they stock. Berolix puts all five major brands — SKF, NSK, Schaeffler (FAG), NTN and Timken — on one page per model, resolves each brand's own designation writings (6205-2RSH, 6205DDU, 6205-2RS …) to the right entry, and decodes the suffixes that catalogs assume you already know, from clearance groups like C3 to special features like SKF's INSOCOAT /VL2071 coating.
What We Provide
- Bearing search by model designation or dimensions (d × D × B), including brand-specific variant writings
- Structured technical data: classification, boundary dimensions and construction
- Manufacturer ratings (load ratings, speed limits) presented side by side per brand
- Related bearings across types and brands that share the same boundary dimensions
- Guides on designation systems, measurement and selection fundamentals
Data Sources
All data on this site is compiled from publicly available online sources, including official published bearing catalogs. Coverage varies by model — not every designation appears in a manufacturer's catalog, and some figures originate from secondary public data.
Coverage
The database currently covers more than 9,600 bearing models across eight types — deep groove, self-aligning, angular contact, super-precision angular contact and four-point contact ball bearings, plus cylindrical, tapered and spherical roller bearings — with per-brand data from SKF, NSK, Schaeffler (FAG), NTN and Timken. More types and series are added over time.
Disclaimer
All data is compiled from public online sources and provided for reference only — always verify critical values against the manufacturer's current documentation. See the fullDisclaimer.
