Decoding SKF 3203 A-2RS1TN9/MT33
- 32Series
- Double row angular contact ball bearings, 32 series. Series differ in outside diameter and width even when the bore is the same.
- 03Bore
- Bore 17 mm: by standard, 03 designates 17 mm.
- A-2RS1TN9/MT33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3203 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3203 A-2RS1TN9/MT33 measures 17 mm across the bore and 40 mm across the outside diameter; its width is 17.5 mm (17 x 40 x 17.5 mm).

When an application pushes a shaft in both directions at once, a double row angular contact bearing is often the answer. SKF builds these with two ball rows on inclined raceways, so they take combined radial and axial loads from either side and also resist tilting moments. Machine tool spindles, pumps, gearboxes and transmission equipment are typical homes for them. MR Industrial Accessories supplies this SKF line to maintenance and purchasing teams across the United States and Latin America.
Reading the code tells you most of what you need. Take 3200 A-2RS1TN9/MT33: 3200 is the dimension series, A is an internal variant, 2RS1 means rubber seals on both sides, TN9 is the polyamide cage, and MT33 identifies the grease. Suffixes can also cover internal clearance or precision class. Decoding them correctly is the first step in picking the right bearing.
You will find these bearings in machine tool spindles, centrifugal pumps, compressors, speed reducers, power transmission equipment and textile machinery. Because they accept axial load in both directions, they suit setups that demand rigidity and precision, such as milling heads or robot axes.
Selection comes down to load size and direction, running speed and the environment. The 2RS1 seals keep contaminants out and lubrication in, which helps in dirty or damp locations. A TN9 polyamide cage cuts weight and supports higher speeds. At mounting, align the components carefully and apply the specified preload so clearance stays within limits. Lubrication such as MT33 grease plays a direct role in how long the bearing lasts.
Equivalents from other makers exist for this bearing type. Before substituting, confirm that principal dimensions, sealing arrangement and load capacity line up with the original. Interchange tables from SKF, FAG, NSK or NTN are useful, but always verify compatibility rather than assuming it.

Frequently asked questions
- SKF 3203 A-2RS1TN9/MT33 bearing: what are its dimensions?
- SKF 3203 A-2RS1TN9/MT33 measures 17 mm across the bore and 40 mm across the outside diameter; its width is 17.5 mm (17 x 40 x 17.5 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3203.
- What does the 2RS1 suffix mean on an SKF bearing?
- It tells you the bearing carries rubber seals on both sides. Those seals block contaminants and hold the lubricant in place, which helps service life in harsh conditions.
- What is the difference between a single row and a double row bearing?
- A double row bearing uses two ball rows, so it handles axial loads in both directions plus tilting moments. A single row version takes axial load in one direction only and normally has to be mounted in pairs.
- How do I choose the right angular contact bearing for my application?
- Look at radial and axial loads, speed, environment and the space available, then check seal type, cage and lubrication. Send us your equipment details and we will help you select the correct SKF bearing.
