How the 6216-ZZ-NSK model number is decoded

6216-ZZ carries two non-contact sheet-steel shields that hold the factory grease in and keep coarse debris out; they do not seal against liquids. 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 catalogue order number: 6216ZZ (suffix ZZ), two non-contact steel shields, mapped here from the industry-neutral -ZZ spelling.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount this 80 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 62xx light series is the default general-purpose section at 80 mm bore; before upgrading to a 6316 for extra capacity, confirm the housing accepts a 140 mm OD and 26 mm width — it is not a drop-in swap.
• ZZ shields are non-contact: 6216-ZZ-NSK blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 6216-2RS for that.
• Do not wash 6216-ZZ-NSK in solvent before mounting: the grease inside the shielded cavity is the service fill, and solvent creeping past the shield gap strips it out.
• Suffixes stack in a defined order — clearance follows the seal code, e.g. 6216-ZZ-NSK-C3. No clearance suffix means normal CN clearance.
• 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-ZZ-NSK drags the lip and overheats it.
• NSK catalogues the shielded version as 6216ZZ — suffix ZZ, two non-contact steel shields. The industry-neutral page spelling is -ZZ; quote the NSK order number when buying through an NSK channel.
• 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 6216ZZ 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 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.
• 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.
