How the 6016-ZZ-NSK model number is decoded

6016-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 extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 16 by five gives the 80 mm bore; the 125 mm outside diameter and 22 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: 6016ZZ (suffix ZZ), two non-contact steel shields, mapped here from the industry-neutral -ZZ spelling.

Typical equipment & failure modes

Common applications

  • heavy conveyors
  • pulp and paper machinery
  • medium and heavy industrial drives
  • large gearboxes

Known failure patterns

  • fine-particle abrasion when non-contact shields let dust past in dirty duty
  • grease aging in the shield-for-life cavity with no relubrication path
  • 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 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.
  • Choosing the 60xx extra-light section saves radial space at 80 mm bore, but the trade-off is rating: if the drive sees shock or frequent start-stop cycles, re-check the L10 life against a 6216 before committing to the smaller envelope.
  • ZZ shields are non-contact: 6016-ZZ-NSK blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 6016-2RS for that.
  • Shielded 6016-ZZ-NSK units are typically greased for life; prying the shields out for regreasing usually bends them and leaves a gap that throws grease in service.
  • Grease compatibility is not guaranteed between fills: mixing lithium and polyurea thickeners in a 6000-series position can soften the mixture and leak — clean out the old fill before switching grease types.
  • Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
  • NSK catalogues the shielded version as 6016ZZ — 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 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 6016ZZ 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.
  • 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.
  • When replacing a failed unit, inspect the shaft and housing seats before fitting the new 6016 — a new bearing pressed onto a worn or oval seat reproduces the original failure mode in a fraction of its expected life.

Frequently asked questions

What are the dimensions of a 6016-ZZ-NSK bearing?

A 6016-ZZ-NSK deep-groove ball bearing has a 80 mm bore, 125 mm outer diameter and 22 mm width (3.15 × 4.921 × 0.866 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields.

How does the 6000 compare with other series at the same 80 mm bore?

The second digit is the diameter series: 60 is the smallest standard section (125×22 mm, 22.5 mm radial section) at 80 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.

Are 6016 bearings from different brands interchangeable?

For boundary dimensions, yes: every brand's 6016 uses the same ISO 15 envelope (80×125×22 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting. Seal suffixes also differ by brand (2RS, DDU, LLU, 2RSL and similar).

What is the NSK suffix for a sealed 6016?

NSK uses suffix DDU for the contact rubber seal (catalogue number 6016ZZ), 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 80×125×22 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. 6016ZZ keeps the same ISO 15 envelope either way.
