How the 6036-RSR model number is decoded
In the 6000-series (diameter series 0 of ISO 15) 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. NSK's non-contact seal suffix is VV (catalogue number 6036VV), mapped here from the industry-neutral -RSR spelling; speed capability is close to the open bearing but VV is not liquid-tight.
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.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 6036-C3. No clearance suffix means normal CN clearance.
- NSK catalogues this low-friction non-contact seal as 6036VV (suffix VV), mapped here from the industry-neutral -RSR spelling. NSK rates its speed capability close to the open bearing, but VV is not liquid-tight — for wet or fine-dust duty step up to the DDU contact seal (industry-neutral -2RS).
- The 180 mm bore places 6036 in NSK's large-size range; at these diameters the pressed-steel cage is speed-limited and NSK commonly supplies a machined brass cage (suffix M) as an option. Verify cage material and relubrication interval with the NSK distributor, and do not extrapolate small-bore speed ratings to this size.
- NSK rates 6036 at 198 kN dynamic (C) and 185 kN static (C0); this heavy-load rating is at the upper end of the E1103 Part C single-row deep-groove extract — NSK supplies a machined brass cage (suffix M) and expects an application review, because catalogue L10 life alone does not capture shock and misalignment loads at this rating.
- At 8880 g (8.9 kg), 6036 is a heavy NSK bearing that requires a crane or hoist for handling; induction-heat the inner ring (max 120 °C) and use a mechanical puller for removal — never apply heat directly to the balls or cage.
- The 180×280×46 mm envelope of 6036 gives a D/d ratio of 1.56 and 50.0 mm radial section height — this NSK thin section saves space but is sensitive to misalignment and shock; confirm the housing stays round within IT7 and the shaft does not deflect past the raceway contact angle under load.
- The 198/185 kN load ratings, mass 8880 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6036VV on the 180×280×46 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6036 in a rated drive. NSK does not tabulate reference or limiting speeds in the E1103 Part C dimension tables used for this page — consult NSK's separate speed-rating tables before high-speed service.
- NSK does not recommend washing new shielded or sealed bearings; the rust-preventive film on open units is compatible with standard lithium greases and needs no removal unless the application demands a special fill.
- NSK supplies its sealed units pre-greased for general duty between roughly -10 and +110 °C; low-temperature, food-grade and high-temperature fills are special executions — ask at order time, because DDU/VV units are not designed to be opened and repacked.
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.
What is the NSK suffix for a sealed 6036?
NSK uses suffix DDU for the contact rubber seal (catalogue number 6036VV), VV for the non-contact rubber seal, and ZZ for steel shields. The industry-neutral spellings on this page (-2RS / -RSR / -ZZ) map to those NSK suffixes while keeping the 180×280×46 mm ISO 15 envelope.
What is the difference between NSK VV and DDU seals?
VV is a non-contact rubber seal: low torque, speed close to the open bearing, dust-tight but not liquid-tight. DDU is a contact rubber seal: far better exclusion of moisture and fine dust, at the cost of a lower speed ceiling and higher running torque. 6036VV keeps the same ISO 15 envelope either way.
