Single Row Angular Contact Bearings: 7000, 7200, 7300, 7900 Size Chart

Same bore, six series

At a 25 mm bore the 7900 is the thinnest and the 7300 the heaviest. The H-prefixed precision series share the boundary dimensions of the 7900 and 7000 sizes. The section height is (D − d) / 2.

How angular contact bearing numbers are built

Number or suffix	Meaning	Example
719xx / 70xx / 72xx / 73xx	Ultra-light / light / medium-light / medium series at the same bore	7905, 7005, 7205, 7305
Last two digits	00 = 10 mm, 01 = 12 mm, 02 = 15 mm, 03 = 17 mm. From 04 up, bore = code × 5.	7205 = 25 × 52 × 15
C / AC / B	Contact angle 15° / 25° / 40°. A smaller angle suits higher speed; a larger angle carries more axial load.	H7005C, H7005AC
No letter	The contact angle is not in the number. Confirm it before ordering.	7205
H70xx / H719xx	Precision series with the same d, D and B as 70xx and 719xx	H7005C = 25 × 47 × 12
HQ1	Ceramic balls (hybrid bearing): lighter balls for higher speed and less heat	H7005C-2RZ/P4 HQ1
DB / DF / DT	Matched pairs: back-to-back / face-to-face / tandem	7205 DB

Single row angular contact size charts

Each row is one size. Versions with different contact angles or suffixes are listed together and link to their model pages, where load ratings are given. Dimensions are in millimetres.

Dimensions are the same as on each model page. The H-prefixed precision series are listed separately from the standard series of the same size.

Mounting and selection checks

One bearing takes axial load in one direction only. Fit a second bearing or a matched pair for axial load in both directions.
Back-to-back (DB) gives the stiffest arrangement against tilting. Face-to-face (DF) tolerates more misalignment. Tandem (DT) shares a high one-way axial load.
Preload is set by the pair and the mounting. State the arrangement and the preload class or value when ordering pairs.
Choose the contact angle with the load: 15° for speed and light axial load, 25° as a common spindle choice, 40° for high axial load.

Custom angular contact bearings

We make matched pairs, special contact angles, preload and non-catalog sizes to drawing. Send the arrangement, d, D, B, contact angle, preload, speed, precision class and quantity.

Frequently asked questions

What is the difference between 7205C and 7205AC?

Both are 25 × 52 × 15 mm. C means a 15° contact angle and AC a 25° contact angle. AC carries more axial load; C suits higher speed.

Can a 7205 replace a 6205?

The boundary dimensions are the same, but a single 7205 carries axial load in one direction only and needs a mating bearing. The shaft arrangement must be redesigned for it.

Why are angular contact bearings mounted in pairs?

One bearing pushes the shaft one way under load. A second bearing, facing the other way, holds the shaft axially in both directions and lets you set preload.

What does H mean in H7005C?

On our model pages H marks the precision series. H7005C has the same 25 × 47 × 12 mm dimensions as a 7005C.
