How the 6006-RSR model number is decoded
In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6006 carries bore code 06 = 30 mm. Outside diameter 55 mm and width 13 mm come from the ISO 15 boundary-dimensions general plan. Suffix -RSR denotes two low-friction non-contact elastomer seals; they keep coarse debris out with minimal drag but are not liquid-tight. For normal-load mounting with a rotating inner ring on a 30 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. SKF's low-friction seal suffix is 2RSL/2RZ (this page's industry-neutral spelling is -RSR); catalogue number 6006-2RZ.
Typical equipment & failure modes
Common applications
- small gearboxes
- conveyors and drives
- agricultural equipment
- fans and blowers
Known failure patterns
- ingress of fine dust or moisture past the non-contact lip in dirty or wet duty (RSR is not liquid-tight)
- lip-lubricant starvation if the bearing runs dry for extended periods
- false brinelling from vibration while the shaft is stationary
- fretting corrosion on a loose shaft seat
Selection pitfalls — read before you substitute
- A 30 mm shaft for 6006 should be finished to Ra ≤ 1.6 µm with square seating faces; at this bore a scored or oval journal shows up directly as running noise and early raceway damage.
- Choosing the 60xx extra-light section saves radial space at 30 mm bore, but the trade-off is rating: if the drive sees shock or frequent start-stop cycles, re-check the L10 life against a 6206 before committing to the smaller envelope.
- The low-drag lip of 6006-RSR barely touches the inner ring; after long shelf storage the grease can separate, so rotate the rings by hand and confirm smooth, silent running before fitting.
- The non-contact lip of 6006-RSR does not retain a lifetime grease fill the way a contact seal does; confirm the regreasing interval for the 30 mm bore position before relying on it as sealed-for-life.
- Measure the shaft, do not trust the drawing: a 30 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6006-RSR.
- Shaft and housing fillets must clear the bearing chamfer so the 13 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
- SKF catalogues the low-friction seal as 6006-2RZ (suffix -2RSL or -2RZ): a non-contact elastomer lip that runs near the open 14000 r/min limiting speed. It keeps coarse debris out without the drag of a contact seal, but is not liquid-tight — use 2RSH for wet or fine-dust positions.
- The 13.8/8.3 kN ratings here are SKF Explorer-class figures from catalogue PUB BU/P1 17000/1 EN (Oct 2018); SKF can revise internal geometry and ratings without changing the designation, so treat the catalogue version and date as part of the specification and re-verify for critical drives.
Frequently asked questions
What are the dimensions of a 6006-RSR bearing?
A 6006-RSR deep-groove ball bearing has a 30 mm bore, 55 mm outer diameter and 13 mm width (1.181 × 2.165 × 0.512 in), per ISO 15 boundary dimensions. It is fitted with two low-friction non-contact rubber seals.
How should 6006-RSR be mounted?
Apply the mounting force to the ring being fitted: on a 30 mm shaft seat the press load must pass through the inner-ring face only. A fitting sleeve and an arbor press are normally sufficient at this size. Never strike the outer ring, the cage or the seals.
What lubrication does 6006-RSR need?
6006-RSR is supplied pre-greased for life and is not designed to be opened for relubrication; where a relubrication path is required, specify the open 6006 with a housing grease fitting instead.
How does the 6006 bore code work?
The last two digits of 6006 are bore code 06, giving 06 × 5 = 30 mm bore. The 55 mm outside diameter and 13 mm width follow the ISO 15 diameter series, not the bore code alone.
What is the SKF designation and catalogue data for 6006-RSR?
In the SKF Rolling Bearings catalogue this size is listed as 6006-2RZ — two low-friction non-contact elastomer seals, 30×55×13 mm per ISO 15. Quoted values: C 13.8 kN, C0 8.3 kN, Pu 0.355 kN, limiting speed 14000 r/min, mass 120 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6006-RSR.
