How the 6036-RSR model number is decoded
In the 6000-series (ISO 15 diameter series 0) the last two digits encode the bore: 6036 carries bore code 36 = 180 mm. Outside diameter 280 mm and width 46 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 180 mm shaft, typical catalogue practice is a m6 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude.
Typical equipment & failure modes
Common applications
- medium and heavy industrial drives
- large gearboxes
- industrial fans and blowers
- hoists and winches
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
- electrical pitting in VFD-driven motors without grounding protection
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- Mount this 180 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 60xx extra-light section at 180 mm bore uses a smaller 280 mm OD than a 6236; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- RSR low-friction seals on 6036-RSR run faster than contact-seal 6036-2RS but let fine dust and moisture past the non-contact lip; in dirty or wet duty specify 6036-2RS instead.
- The non-contact lip of 6036-RSR does not retain a lifetime grease fill the way a contact seal does; confirm the regreasing interval for the 180 mm bore position before relying on it as sealed-for-life.
- Shaft and housing fillets must clear the bearing chamfer so the 46 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
- NSK catalogues this low-friction non-contact seal as 6036VV (suffix VV), the NSK equivalent of the industry-neutral -RSR spelling on this page. VV is not liquid-tight; NSK's contact-seal suffix DDU (industry-neutral -2RS) is the choice for wet or fine-dust duty.
- The 198/185 kN ratings, mass 8880 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6036VV; this seal/size combination has no counterpart in the SKF 17000 extract used elsewhere on this site, so the page rests on a single manufacturer source — internal geometry and ratings legitimately differ between brands, so re-verify before substituting in a rated drive.
Frequently asked questions
What are the dimensions of a 6036-RSR bearing?
A 6036-RSR deep-groove ball bearing has a 180 mm bore, 280 mm outer diameter and 46 mm width (7.087 × 11.024 × 1.811 in), per ISO 15 boundary dimensions. It is fitted with two low-friction non-contact rubber seals.
How does the 6036 bore code work?
The last two digits of 6036 are bore code 36, giving 36 × 5 = 180 mm bore. The 280 mm outside diameter and 46 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the RSR suffix on 6036-RSR mean?
RSR means two low-friction non-contact rubber seals. They keep coarse debris out with minimal drag (speed close to the open bearing) but are not liquid-tight; use -2RS contact seals for wet or fine-dust environments.
How does the 6000 compare with other series at the same 180 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (280×46 mm, 50.0 mm radial section) at 180 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
What is the NSK designation and catalogue data for 6036-RSR?
In the NSK Rolling Bearings catalogue (E1103 Part C) this size is listed as 6036VV — two low-friction non-contact rubber seals (NSK suffix VV), 180×280×46 mm per ISO 15. Quoted values: C 198 kN, C0 185 kN, mass 8880 g. The industry-neutral page spelling 6036-RSR follows the seal-suffix convention used across this site, not NSK order-number spelling. Reference and limiting speeds are not tabulated in the E1103 dimension tables used here; consult NSK speed tables before high-speed service.
