How the 6017-2RS-NSK model number is decoded
In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6017 carries bore code 17 = 85 mm. Outside diameter 130 mm and width 22 mm come from the ISO 15 boundary-dimensions general plan. Suffix -2RS denotes two contact-type elastomer seals over a lifetime grease fill; the sealing lips add drag compared with open or shielded versions. For normal-load mounting with a rotating inner ring on a 85 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. NSK's contact-seal catalogue number is 6017DDU (suffix DDU), mapped here from the industry-neutral -2RS spelling; it is greased for life and the contacting lip lowers the speed ceiling versus the open bearing.
Typical equipment & failure modes
Common applications
- medium and heavy industrial drives
- large gearboxes
- industrial fans and blowers
- hoists and winches
Known failure patterns
- seal-lip hardening and loss of pre-grease in sustained high-temperature service
- grease-life expiry in the sealed-for-life cavity (no relubrication path)
- edge loading from shaft deflection or housing misalignment
- rolling-contact fatigue spalling after the rated L10 life is exceeded
Selection pitfalls — read before you substitute
- At 85 mm bore the ring mass is significant: heat 6017 on an induction heater (max 120 °C), never over an open flame, and plan puller access or a withdrawal sleeve now for the day it has to come off again.
- The 60xx extra-light section at 85 mm bore uses a smaller 130 mm OD than a 6217; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- Contact seals add drag and heat: 6017-2RS-NSK runs slower and cooler-limited than the open 6017; rubber lips are generally limited to roughly 80–110 °C continuous depending on grease, and C3 clearance is the common hot-duty choice.
- Heat is the enemy of the sealed 6017-2RS: sustained running near the lip temperature limit hardens the rubber, after which grease escapes and dirt tracks in — watch the housing temperature in hot drives.
- The housing bore for the 130 mm OD should be round within IT7; an oval bore pinches the outer ring of 6017-2RS-NSK and shows up later as two-point loaded raceway wear.
- Deep-groove ball bearings tolerate only minutes of misalignment; if the 130 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 6017-2RS-NSK.
- NSK catalogues the contact-sealed version as 6017DDU (suffix DDU), mapped here from the industry-neutral -2RS spelling; it is greased for life and the contacting lip lowers the speed ceiling versus the open bearing. NSK's DDU lip design is single-lip contact, so grease life is longer than VV but drag torque is higher.
- At 85 mm bore 6017 is in NSK's medium industrial range; the pressed-steel cage is standard, but large-section 63xx sizes at this bore can be ordered with a machined brass cage (suffix M) for heavy-shock or very-low-speed duty — confirm cage material with the NSK channel if the application sees impact loads.
- NSK rates 6017 at 54.5 kN dynamic (C) and 43 kN static (C0); this upper-medium rating covers conveyor and gearbox drives, but at these loads the pressed-steel cage can be the limiting factor under shock — consider the machined brass cage (suffix M) for impact duty.
- At 918 g, 6017 requires a soft-jaw vise or arbor press for mounting — never hammer it onto the shaft, and support the opposite ring to avoid brinelling the raceways.
- The 85×130×22 mm envelope of 6017 gives a D/d ratio of 1.53 and 22.5 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 54.5/43 kN load ratings, mass 918 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6017DDU on the 85×130×22 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6017 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's VV non-contact seal keeps frictional torque close to the open 6017; in motor duty where heat build-up matters, VV is the usual compromise between debris protection and speed capability.
Frequently asked questions
What are the dimensions of a 6017-2RS-NSK bearing?
A 6017-2RS-NSK deep-groove ball bearing has a 85 mm bore, 130 mm outer diameter and 22 mm width (3.346 × 5.118 × 0.866 in), per ISO 15 boundary dimensions. It is fitted with two contact rubber seals and is normally pre-greased.
How does the 6017 bore code work?
The last two digits of 6017 are bore code 17, giving 17 × 5 = 85 mm bore. The 130 mm outside diameter and 22 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the 2RS suffix on 6017-2RS mean?
2RS means two contact elastomer seals, one each side, usually over a lifetime grease fill. Sealing against dust and moisture is better than ZZ shields, but the lip drag lowers the speed and temperature ceiling.
What is the NSK suffix for a sealed 6017?
NSK uses suffix DDU for the contact rubber seal (catalogue number 6017DDU), 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 85×130×22 mm ISO 15 envelope.
Does NSK offer 6017 with C3 clearance?
NSK lists C3 (and C4) internal-clearance options for most deep-groove sizes under the same base designation; the clearance is fixed at manufacture, so specify it at order time rather than planning to adjust later.
