Decoding SKF 3214 A-2Z/MT33
- 32Series
- Double row angular contact ball bearings, 32 series. Series differ in outside diameter and width even when the bore is the same.
- 14Bore
- Bore 70 mm (14 × 5).
- A-2Z/MT33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3214 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3214 A-2Z/MT33 measures 70 mm across the bore and 125 mm across the outside diameter; its width is 39.7 mm (70 x 125 x 39.7 mm).

When a machine needs to handle both radial and axial forces but space is tight, a double row angular contact bearing can be the answer. SKF's 32 series packs two rows of balls into one unit, providing the rigidity and capacity of a pair of single row bearings without the extra width. These bearings come with 2Z metal shields and MT33 factory grease, making them ready to install in many industrial settings.
The part number tells you a lot. Take 3206 A-2Z/MT33: the first four digits (3206) indicate the size and dimension series, while the letter A denotes an internal design variation. The 2Z means there are two metal shields, one on each side, which keep grease in and coarse debris out. MT33 is the specific grease filled at the factory. So a 3212 A-2Z/MT33 or 3214 A-2Z/MT33 follows the same logic.
You'll find these bearings in electric motors, pumps, fans, compressors, machine tools, and transmission systems. They suit combined loads at moderate speeds, especially where a single row bearing would be insufficient but two separate bearings won't fit.
Selection depends on the radial and axial loads, speed, and operating environment. The metal shields don't contact the races, so they allow higher speeds than rubber seals, but they aren't liquid-tight. MT33 grease is typically good for the bearing's life, so relubrication is rarely needed. During mounting, align the shaft and housing carefully and avoid impacts. For dusty or wet conditions, consider a rubber-sealed version.
SKF 32 series bearings can be interchanged with other brands that use the same dimensional and suffix system. For instance, an SKF 3206 A-2Z/MT33 matches another maker's 3206 with 2Z and similar grease. Always check tolerances and internal clearance before substituting.

Frequently asked questions
- SKF 3214 A-2Z/MT33 bearing: what are its dimensions?
- SKF 3214 A-2Z/MT33 measures 70 mm across the bore and 125 mm across the outside diameter; its width is 39.7 mm (70 x 125 x 39.7 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3214.
- What does the 2Z suffix mean on an SKF bearing?
- 2Z indicates two metal shields, one on each side. These steel shields retain grease and block larger particles, but they do not seal against liquids. Because they don't rub, they are suitable for higher speeds.
- Does MT33 grease require maintenance?
- MT33 is a factory-filled grease designed to last the bearing's service life under normal conditions. Relubrication is usually not needed. For extreme temperatures or heavy loads, consult us.
- Can I replace a bearing from another brand with this SKF one?
- Yes, if the dimensional designation and suffixes match. For example, an SKF 3206 A-2Z/MT33 is interchangeable with another brand's 3206 A-2Z/MT33. Verify tolerances and internal clearance, and if in doubt, send us the code on WhatsApp.
