The 6000 is a single-row deep groove ball bearing with a 10 mm bore, 26 mm outside diameter and 8 mm width (10x26x8 mm). Those boundary dimensions are set by ISO 15, so a 6000 from SKF, FAG, NSK, NTN, Koyo or any budget brand is dimensionally interchangeable - the differences are in materials, precision grade, internal clearance and seal design, not size.

6000 bearing dimensions

Property	Value	Standard
Bore diameter (d)	10 mm	ISO 15
Outside diameter (D)	26 mm	ISO 15
Width (B)	8 mm	ISO 15
Bearing type	Single-row deep groove ball bearing	ISO 15
Dimension series	6000 (light)	ISO 15

Always measure a worn bearing before ordering if the number is unreadable: bore with calipers on the inner ring, outside diameter across the outer ring, and width across either ring face. 10x26x8 mm identifies the 6000 uniquely among common metric sizes.

What the suffixes mean (6000ZZ, 6000-2RS, 6000-C3)

Suffix	Meaning	When to choose it
ZZ / 2Z	Metal shield both sides	Non-contact, low friction, keeps debris out. Not washdown-proof.
2RS / 2RS1 / DDU / LLU	Rubber seal both sides	Contact seals, best dirt and moisture exclusion, slightly more friction.
Z / RS	Shield or seal one side only	Open on the other side - used where relubrication is needed.
Open (no suffix)	No seals or shields	For housings with their own sealing and external lubrication.
C3	Extra internal clearance	For motors and anywhere the inner ring runs hotter than the outer.
2RS-C3	Sealed + C3 clearance	The standard electric-motor spec.

Brand equivalents for the 6000

Every major manufacturer makes the 6000. The seal and shield codes differ by brand but the bearings interchange directly:

Brand	Shielded version	Sealed version
SKF	6000-2Z	6000-2RSH
FAG (Schaeffler)	6000-2ZR	6000-2RSR
NSK	6000ZZ	6000DDU
NTN	6000ZZ	6000LLU
Koyo (JTEKT)	6000ZZ	6000-2RS

Load ratings: check the maker's catalogue

Dynamic (C) and static (C0) load ratings for the 6000 differ between manufacturers and between standard and premium ranges, so MLC does not publish a single figure. Look the value up in the manufacturer's own catalogue for the exact variant you are buying - SKF, Schaeffler medias, NSK and NTN all publish free online catalogues with per-variant ratings, limiting speeds and grease specifications.

Where the 6000 is used

The 6000 (light) series is lightest loads of the three common series, most compact. Typical 6000 applications include electric motors, gearboxes, pumps, fans, conveyor rollers, power tools and general machinery - anywhere a rotating shaft of 10 mm needs simple radial support with modest axial capability.

Fitting basics

For a rotating shaft (the normal case), fit the inner ring with a light interference (k5/k6 shaft tolerance for most machinery) and the outer ring with a close clearance fit (H7 housing). Press only on the ring you are fitting - pressing the outer ring through the balls to seat the inner ring is the fastest way to brinell a new bearing. For sealed 2RS variants, no relubrication is needed or possible; the factory grease fill is for life.

Frequently Asked Questions

What size is a 6000 bearing?

A 6000 bearing measures 10 mm bore x 26 mm outside diameter x 8 mm width. These boundary dimensions are fixed by ISO 15 and identical across all manufacturers.

What does 6000-2RS mean?

The 2RS suffix means the 6000 has rubber contact seals on both sides. It keeps grease in and dirt and moisture out, and is the right choice for most machinery. ZZ means metal shields instead - lower friction but less sealing.

Are 6000 bearings interchangeable between brands?

Yes. ISO 15 fixes the 6000's dimensions at 10x26x8 mm for every maker, so an SKF 6000 swaps directly with FAG, NSK, NTN or Koyo. Match the suffix too: SKF 2RSH, NSK DDU and NTN LLU are all the sealed version.

What is the C3 suffix on a 6000 bearing?

C3 means greater-than-normal internal clearance. Electric motors and hot-running applications use C3 because the inner ring expands more than the outer in service; standard clearance would leave the bearing too tight when warm.
