Decoding SKF 3313 DNRCBM
- 33Series
- Double row angular contact ball bearings, 33 series. Series differ in outside diameter and width even when the bore is the same.
- 13Bore
- Bore 65 mm (13 × 5).
- DNRCBMSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3313 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3313 DNRCBM measures 65 mm across the bore and 140 mm across the outside diameter; its width is 58.7 mm (65 x 140 x 58.7 mm).

For applications that combine radial and axial loads in both directions, SKF DNRCBM series double row angular contact bearings provide a compact solution. These bearings use two rows of balls and inclined raceways to handle higher axial loads than a single row deep groove bearing. They are commonly found in gearboxes, pumps, and transmission equipment where rigidity and precision matter. MR supplies this SKF line and helps you choose the right part number.
The part number structure reveals key design features. In examples like 3308 DNRCBM, 3310 DNRCBM, 3311 DNRCBM, and 3313 DNRCBM, the first two digits (33) identify the double row angular contact series. The next two digits indicate the bore size, which changes with each part number. The DNRCBM suffix carries information about internal design, sealing, and cage—details worth checking against your application.
These bearings suit equipment where axial loads act in both directions and space is tight. Typical installations include gearboxes, centrifugal pumps, compressors, machine tools, and power transmission systems. They also appear in mining, cement, and food processing facilities that demand robust load capacity. Because the double row design integrates two rows into one unit, it can simplify housing design compared to using two single row bearings.
When selecting a bearing, consider load magnitude and direction, rotational speed, and environmental conditions. The sealing indicated by the suffix determines protection against dust and moisture; for dirty or humid settings, opt for sealed versions. Lubrication must match temperature and speed—many units come factory-lubricated, but verify compatibility with your operating conditions. Proper assembly requires careful alignment and attention to internal clearance, which can be affected by shaft and housing fits.
When replacing a bearing from another brand, standardized dimensions allow cross-referencing, but don't rely on part numbers alone. Compare bore, outer diameter, and width, and confirm that load capacity and speed ratings meet your needs. MR can help you identify interchangeability, but always check original equipment specifications. If you have an old bearing or housing measurements, share them with us for guidance.

Frequently asked questions
- SKF 3313 DNRCBM bearing: what are its dimensions?
- SKF 3313 DNRCBM measures 65 mm across the bore and 140 mm across the outside diameter; its width is 58.7 mm (65 x 140 x 58.7 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3313.
- What does the DNRCBM suffix mean on an SKF bearing?
- The DNRCBM suffix combines several indications about internal design, cage type, and sealing. It is specific to SKF and not a universal code. For an accurate interpretation, consult the manufacturer's catalog or send us the part number and we'll help identify the features.
- Is this bearing suitable for axial loads in both directions?
- Yes, the double row angular contact design supports axial loads in both directions along with radial loads. This is an advantage over single row bearings, which accept axial load in only one direction. Always check the load limits for the specific part number.
- How do I know if I can replace a bearing from another brand with this SKF one?
- Interchangeability is based on standardized dimensions and load conditions. Compare bore, outer diameter, and width, and verify that load capacity and speed are suitable. Do not rely only on the part number. MR can advise you on finding the correct equivalent.
