3300 / 5300 Double Row Angular Contact Bearings Size Chart

Double-row series at a 25 mm bore

The same 25 mm bore is available in six double-row series. The cross-section height is (D − d) / 2. A larger section and width carry more load and need more space.

Model	Series	d	D	B	Section height
3805	3800	25	37	10	6
3905	3900	25	42	13	8.5
3005	3000	25	47	16	11
3205	3200 / 5200	25	52	20.6	13.5

How 3300 and 5300 numbers are built

Number or suffix	Meaning	Example
3300 / 5300	Two names used for the same size range. The last two digits give the bore code.	3305 and 5305 = 25 × 62 × 25.4
Bore code 00–03	00 = 10 mm, 01 = 12 mm, 02 = 15 mm, 03 = 17 mm	5302 = 15 × 42 × 19
Bore code 04 and up	Bore = code × 5 mm	5310 = 50 × 110 × 44.4
ZZ / 2RS	Metal shields / rubber seals on both sides	5305ZZ, 5305-2RS

3300 / 5300 size chart

Each row is one size. 3300, 5300, ZZ and 2RS models of that size are listed together and link to their model pages, where load ratings and drawings are given. Dimensions are in millimetres.

Dimensions are taken from the model pages. Some pages give inch-based widths to three decimals (for example 14.287 mm) and others round them to 0.1 mm (14.3 mm). Both describe the same size, so they share one row.

Selection checks for double-row bearings

The axial clearance or preload is set when the bearing is made. State it as a measured value with the test load, not only as a class name.
A double-row bearing accepts little misalignment. Check shaft and housing alignment before you choose it.
Equal d × D × B does not make two bearings interchangeable. Confirm the full suffix, closure, cage and clearance against the drawing.
Choose the fits and the clearance together. A tight fit reduces the axial clearance in service.

Custom double-row bearings

We make double-row angular contact bearings to drawing: special axial clearance or preload, grooves, non-standard widths and full-complement versions. Send d, D, B, loads, speed, closure and quantity, or a sample.

Frequently asked questions

Is a 3300 bearing the same as a 5300 bearing?

Both names are used for the same boundary dimensions, for example 3305 and 5305 are both 25 × 62 × 25.4 mm. Confirm the full suffix, clearance and internal design before you swap them.

When should I use 3300 instead of 3200?

Use 3300 when the load is higher than a 3200 bearing of the same bore can carry and there is room for the larger OD and width. Compare the load ratings on the two model pages.

Should I choose 2RS or ZZ?

2RS rubber seals keep out more dirt and water. ZZ metal shields run with lower friction. Choose by contamination and speed.

Are 3300 sizes available with seals in every bore?

Not in every size. The table shows which ZZ and 2RS versions have model pages. Ask us for a size that is not listed.
