How the 6216-RSR model number is decoded

6216-RSR uses two non-contact elastomer lips with very low drag; coarse debris stays out, but the bearing is not liquid-tight. Within the light 62xx section (diameter series 2 of ISO 15), multiplying bore code 16 by five gives the 80 mm bore; the 140 mm outside diameter and 26 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 80 mm shaft under normal load, catalogue practice seats it on a k5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. NSK's non-contact seal suffix is VV (catalogue number 6216VV), 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

• At 80 mm bore the ring mass is significant: heat 6216 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.
• At 80 mm bore the 62xx light series is the workhorse section; its 140×26 mm envelope is what most motor and gearbox seats are machined for, so any alternative section must be checked against both this OD and this width, not the bore alone.
• RSR low-friction seals on 6216-RSR run faster than contact-seal 6216-2RS but let fine dust and moisture past the non-contact lip; in dirty or wet duty specify 6216-2RS instead.
• The non-contact lip of 6216-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 26 mm-wide ring of 6216-RSR drags the lip and overheats it.
• Suffixes stack in a defined order — clearance follows the seal code, e.g. 6216-C3. No clearance suffix means normal CN clearance.
• NSK catalogues this low-friction non-contact seal as 6216VV (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 6216 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.
• At 80 kN dynamic load rating (C) and 53 kN static (C0), 6216 is a heavy-load NSK bearing for industrial gearboxes and large conveyors; NSK expects a machined brass cage (suffix M) at this rating for shock duty, and the static C0 must be checked against any mounting or lifting loads.
• At 1420 g (1.4 kg), 6216 needs mechanical handling for mounting; NSK recommends induction heating the inner ring (max 120 °C) rather than pressing cold, and a lifting eye if the housing is pre-assembled.
• The 80×140×26 mm envelope of 6216 gives a D/d ratio of 1.75 and 30.0 mm radial section height — a standard NSK medium section that balances load capacity and speed; for this geometry the pressed-steel cage is adequate up to NSK's listed speed ratings, and C3 clearance is the common choice for hot shafts.
• The 80/53 kN load ratings, mass 1420 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6216VV on the 80×140×26 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6216 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's VV non-contact seal keeps frictional torque close to the open 6216; in motor duty where heat build-up matters, VV is the usual compromise between debris protection and speed capability.
• Standard P0 runout from NSK is adequate up to the catalogue limiting speed on ground shaft seats; spindle or instrument positions should specify P6/P5 accuracy explicitly — it is a different order code, not a sorting of standard stock.
