Ball Bearing Size Chart – 5000 Series

The 5000 series covers angular contact ball bearings — a contact-angle design that lets a single bearing carry combined radial and axial loads at the same time. Unlike deep groove bearings (6000 series) that mainly handle radial load, 5000 series bearings are built for shafts that see thrust in addition to radial force: pumps, gearboxes, machine tool spindles, automotive hubs.

The series breaks into three common sub-series:

 

5100 Series (Single Row)

Single-row angular contact ball bearings. Lightest cross-section in the 5000 family — used where axial load is moderate and space is constrained. Note: a single 5100 bearing carries thrust in one direction only; pair them in DB, DF, or DT arrangements when bidirectional thrust is required.

Bearing	Bore (mm)	Outer Diameter (mm)	Width (mm)
5100	10	30	9
5101	12	32	10
5102	15	35	11
5103	17	40	12
5104	20	47	14
5105	25	52	15
5106	30	62	16
5107	35	72	17
5108	40	80	18
5109	45	85	19
5110	50	90	20
5111	55	100	21
5112	60	110	22
5113	65	120	23
5114	70	125	24
5115	75	130	25
5116	80	140	26
5117	85	150	28
5118	90	160	30
5119	95	170	32
5120	100	180	34

 

5200 Series (Double Row, Standard)

Double-row angular contact ball bearings in the standard cross-section. Two rows of balls handle thrust in both directions and add radial stiffness. Drop-in replacement footprint for many 6200 deep-groove applications when axial capacity is needed.

Bearing	Bore (mm)	Outer Diameter (mm)	Width (mm)
5200	10	30	14.3
5201	12	32	15.9
5202	15	35	15.9
5203	17	40	17.5
5204	20	47	20.6
5205	25	52	20.6
5206	30	62	23.8
5207	35	72	27.0
5208	40	80	30.2
5209	45	85	30.2
5210	50	90	30.2
5211	55	100	33.3
5212	60	110	36.5
5213	65	120	38.1
5214	70	125	39.7
5215	75	130	41.3
5216	80	140	44.4
5217	85	150	49.2
5218	90	160	52.4
5219	95	170	55.6
5220	100	180	60.3

 

5300 Series (Double Row, Heavy)

Heavy cross-section double-row angular contact bearings. Larger outer diameter and width than the 5200 for the same bore, giving higher load ratings. Used in high-thrust applications: heavy gearboxes, machine tool spindles, agricultural drives.

Bearing	Bore (mm)	Outer Diameter (mm)	Width (mm)
5300	10	35	17.5
5301	12	37	17.5
5302	15	42	19.0
5303	17	47	22.2
5304	20	52	22.2
5305	25	62	25.4
5306	30	72	30.2
5307	35	80	34.9
5308	40	90	36.5
5309	45	100	39.7
5310	50	110	44.4
5311	55	120	49.2
5312	60	130	54.0
5313	65	140	58.7
5314	70	150	63.5
5315	75	160	68.3
5316	80	170	68.3
5317	85	180	73.0
5318	90	190	73.0
5319	95	200	77.8
5320	100	215	82.6

 

Comparison: 5000 Series vs Other Series

Quick reference for picking between the 5000 series and adjacent options. All comparisons assume the same bore size.

5000 vs 6100

	5000 Series	6100 Series
Type	Angular contact ball bearing	Single-row deep groove ball bearing (extra-light)
Load direction	Combined radial + axial	Primarily radial, limited axial
Cross-section	Wider, heavier	Thinner, lighter
Use when	Thrust loads are present	Pure radial, space-constrained, lower load

If the application has any meaningful axial load, choose 5000. The 6100 will handle small thrust but is not designed for sustained axial duty.

 

5000 vs 6200

	5000 Series	6200 Series
Type	Angular contact ball bearing	Single-row deep groove ball bearing
Outer diameter	Same as 6200 in 5200 sub-series	Standard reference dimension
Width	Wider (double row)	Narrower
Axial capacity	High, both directions (5200/5300)	Low
Use when	Replacing a 6200 that is failing under thrust	General-purpose radial duty

The 5200 sub-series shares the 6200's bore and OD footprint, which makes it a common upgrade path when an existing 6200 housing needs more thrust capacity. Confirm housing depth — the 5200 is wider.

 

5000 vs 4100

	5000 Series	4100 Series
Type	Double-row angular contact	Double-row deep groove
Contact angle	Yes — supports thrust	None — radial only
Radial capacity	High	Higher than 5000 for same envelope
Axial capacity	High	Minimal
Use when	Combined loads	Pure radial, high load, no thrust

Same form factor, different geometry. If the shaft sees pure radial load and you need maximum radial capacity, the 4100 wins. The moment any thrust enters the picture, switch to 5000.

 

How to Specify a 5000 Series Bearing

1. Measure bore, OD, and width from the existing bearing or shaft/housing.
2. Confirm the load direction — axial only in one direction, both directions, or combined.
3. Match the bore to the table above; the second two digits of the part number give the bore code (e.g., 5208 = 40 mm bore).
4. Check the suffix for contact angle, cage material, and clearance class — these vary by manufacturer.
