6300 Series Bearing Size Chart: 63xx Deep Groove Ball Bearings

Same bore, six series

At a 25 mm bore the series give a range of outside diameters and widths. A larger section carries more load but needs more space. The section height is (D − d) / 2.

Model	Series	d	D	B	Section height
6005	6000	25	47	12	11
6205	6200	25	52	15	13.5
6305	6300	25	62	17	18.5
6405	6400	25	80	21	27.5

How 6000, 6200 and 6300 numbers are built

Number or suffix	Meaning	Example
60xx / 62xx / 63xx / 64xx	Light / medium-light / medium / heavy series at the same bore	6005, 6205, 6305
Last two digits	00 = 10 mm, 01 = 12 mm, 02 = 15 mm, 03 = 17 mm. From 04 up, bore = code × 5.	6205 = 25 × 52 × 15
60x / 62x / 63x	One digit after the series: bore in mm (miniature sizes)	608 = 8 × 22 × 7
ZZ / 2RS / 2RZ	Metal shields / contact rubber seals / non-contact rubber seals	6205 ZZ, 6205 2RS
N / NR	Snap-ring groove in the outer ring / groove with snap ring fitted	60/28N, 60/28NR

6300 series size chart

Each row is one size. Open, shielded, sealed and snap-ring versions of the same size are listed together and link to their model pages, where load ratings and drawings are given. Dimensions are in millimetres.

Dimensions are the same as on each model page. Where a shielded or sealed version is wider than the open one, it is listed in its own row.

Choosing between the series

Start from the shaft diameter, then choose the lightest series that carries the load for the required life. Check the load rating on the model page.
Use ZZ shields for low friction in clean places, 2RS seals where dust or water is the main risk, and 2RZ seals for a middle course with less friction than 2RS.
Choose the wide 622xx, 623xx or W62xx versions when the housing allows more width. The wider ring leaves more room for seals and grease.
With a heavy interference fit or a warm running shaft, the internal clearance shrinks. Consider C3 clearance and state it in the order.

Custom deep groove bearings

We also make non-catalog bores, widths and outside diameters to drawing, and special clearance, seals, grease and cages. Send d, D, B, seal type, clearance, speed and quantity. We check whether a catalog size fits first.

Frequently asked questions

What are the dimensions of a 6305 bearing?

A 6305 bearing is 25 mm mm × 62 × 17 mm (bore × OD × width). The ZZ and 2RS versions have the same dimensions.

What is the difference between 6200 and 6300 bearings?

They share the bore for the same last two digits. A 6300 bearing has a larger outside diameter and width than a 6200, so it carries more load and needs more space.
