Decoding SKF 3307 DJ1
- 33Series
- Double row angular contact ball bearings, 33 series. Series differ in outside diameter and width even when the bore is the same.
- 07Bore
- Bore 35 mm (07 × 5).
- DJ1Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3307 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3307 DJ1 measures 35 mm across the bore and 80 mm across the outside diameter; its width is 34.9 mm (35 x 80 x 34.9 mm).

The SKF double row angular contact bearing is built to handle combined radial and axial loads acting in both directions. Two rows of balls running on inclined raceways give it a rigidity level beyond what a single row bearing offers. Machine tool spindles, pumps, compressors and gearboxes are typical places where this design is specified. MR Industrial Accessories supplies this SKF line.
The part code tells you a lot before you open a catalog. Take 3307 DJ1: the leading digits point to the bearing type and its dimension series, while the DJ1 suffix covers design details such as contact angle or internal clearance. Reading that code correctly is the first step in matching a bearing to the job. Send the full designation if you want help confirming it.
Double row angular contact bearings show up in metalworking, petrochemical, food processing and mining operations. On milling and lathe spindles, process centrifugal pumps, screw compressors and gearboxes they are a common sight. Because they take thrust from either direction, they suit shafts that see alternating axial forces, including industrial fans and mixers.
Selection comes down to the loads involved, the running speed and the surrounding environment. Where contamination is a risk, sealed or shielded versions are the sensible pick. Lubrication has to match the operating regime, and alignment during mounting needs to be precise so the bearing is not stressed. Get the internal clearance wrong and service life can suffer.
Bearings of this type from different manufacturers can sometimes be swapped when dimensions and load capacity line up. Suffixes are where the trouble usually hides, since they may point to different tolerances or clearance. It pays to verify those details rather than assume. SKF is a globally recognized brand, and MR Industrial Accessories works with its products to help you find the right fit.

Frequently asked questions
- SKF 3307 DJ1 bearing: what are its dimensions?
- SKF 3307 DJ1 measures 35 mm across the bore and 80 mm across the outside diameter; its width is 34.9 mm (35 x 80 x 34.9 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3307.
- What does the DJ1 suffix mean on an SKF bearing?
- The DJ1 suffix identifies a specific design variant, usually tied to the contact angle or internal clearance. Check the manufacturer's data sheet or contact us with the complete code so we can interpret it correctly.
- Can this bearing take axial loads in both directions?
- Yes. Double row angular contact bearings are made to carry axial loads in both directions along with radial loads. That is why they work well on shafts with alternating thrust.
- How can I tell if an SKF bearing will replace one from another brand?
- Compare the main dimensions, load capacity and clearance type. Even when dimensions match, suffixes can signal internal design differences. Contact us and we will help you check interchangeability.
