How the 6016-RSR model number is decoded

In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6016 carries bore code 16 = 80 mm. Outside diameter 125 mm and width 22 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 80 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 non-contact seal suffix is VV (catalogue number 6016VV), 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

Selection pitfalls — read before you substitute

• Large bores like the 80 mm of 6016-RSR demand clean, burr-free seats; one raised burr under a ring this size cocks the bearing and concentrates load at the raceway edge, cutting life drastically.
• The 60xx extra-light section at 80 mm bore uses a smaller 125 mm OD than a 6216; 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 6016-RSR run faster than contact-seal 6016-2RS but let fine dust and moisture past the non-contact lip; in dirty or wet duty specify 6016-2RS instead.
• The non-contact lip of 6016-RSR does not retain a lifetime grease fill the way a contact seal does; confirm the regreasing interval for the 80 mm bore position before relying on it as sealed-for-life.
• Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 22 mm-wide ring of 6016-RSR drags the lip and overheats it.
• A 80 mm bore listing showing the right d/D/B but no standard or precision-class reference may be a loose-tolerance import; measure bore/OD spread before fitting it to a machined shaft.
• NSK catalogues this low-friction non-contact seal as 6016VV (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).
• At 80 mm bore 6016 is in NSK's upper general-purpose range; the pressed-steel cage is standard, but mid-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 6016 at 52.5 kN dynamic (C) and 40 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 872 g, 6016 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 80×125×22 mm envelope of 6016 gives a D/d ratio of 1.56 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 52.5/40 kN load ratings, mass 872 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6016VV on the 80×125×22 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6016 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.
• Keep NSK bearings in the original packaging until fitting: the wrapper carries the production lot, and the unopened shelf life of greased sealed units is typically quoted at three to five years in dry, vibration-free storage.
• NSK's VV non-contact seal keeps frictional torque close to the open 6016; in motor duty where heat build-up matters, VV is the usual compromise between debris protection and speed capability.
