How to read SKF 3312 E
- 33Series
- Double row angular contact ball bearings, 33 series. For the same bore, each series has a different outside diameter and width.
- 12Bore
- 60 mm bore: 12 × 5.
- ESuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
3312 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF double row angular contact bearings are components designed to support combined radial and axial loads in both directions. Their construction with two rows of balls at opposite contact angles makes them ideal for applications requiring high rigidity and precision. MR Accesorios Industriales sells this line.
The designation of these bearings follows a clear scheme. For example, in 3209 E, the first two digits indicate the bearing type (32 for double row angular contact), the third digit indicates the dimension series (2 for light series, 3 for medium series), and the last two correspond to the bore diameter. The suffix E indicates an optimized design with higher load capacity. Other examples such as 3311 E or 3316 E follow the same logic, varying in size and series. Knowing this nomenclature lets you quickly identify the main characteristics.
These bearings are used in applications where combined loads and high precision are required. In Argentine industry, they are common in machine tool spindles, centrifugal pumps, compressors, gearboxes and transmission equipment. They also appear in automotive applications, such as vehicle wheels, and in agricultural machinery. Their ability to support axial loads in both directions makes them versatile for equipment that reverses the load direction, such as lifting systems or drive shafts.
To correctly select a double row angular contact bearing, take into account the load it must support, the rotation speed and the environmental conditions. It is essential to verify the sealing: these bearings can be open or sealed, and the choice depends on contamination and lubrication. Internal clearance and preload also affect performance. During mounting, ensure precise alignment and adequate lubrication. The combination of two rows at opposite angles already provides axial guidance, but incorrect installation can reduce service life.
As for equivalences and interchangeability, SKF double row angular contact bearings can be replaced by products from other brands that follow the same dimensional designation. However, not all manufacturers offer exactly the same load capacities or tolerances. That is why it is important to compare technical specifications before replacing a bearing. At MR Accesorios Industriales we can advise you on the corresponding options and compatibilities, always respecting the requirements of your equipment.

Frequently Asked Questions
- What are the dimensions of the SKF 3312 E bearing?
- The SKF 3312 E bearing has a 60 mm bore, a 130 mm outside diameter and a 54 mm width (60 x 130 x 54 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 3312.
- What does the suffix E mean on an SKF bearing?
- The suffix E indicates an optimized bearing design, generally with higher load capacity and better performance. It is common in ball bearings and applies to various series.
- How do I choose between an open and a sealed bearing?
- It depends on the environment: if there are contaminants, choose sealed; if lubrication is external and the environment is clean, choose open. Sealed bearings require less maintenance but may have higher friction.
- Can I replace an SKF bearing with another brand?
- Yes, if the dimensions and load capacities match. Check the tolerances and internal clearance. At MR we advise you so the replacement is safe.
