How the 6016-NSK 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. With no seal suffix the bearing is open: no shields or seals are fitted and lubrication is supplied by the application. 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. In the NSK catalogue this open execution carries the bare designation; protected variants are ordered separately with suffixes ZZ (steel shields), VV (non-contact rubber seals) and DDU (contact rubber seals).

Typical equipment & failure modes

Common applications

  • medium and heavy industrial drives
  • large gearboxes
  • industrial fans and blowers
  • hoists and winches

Known failure patterns

  • contamination wear from dust and dirt ingress through the open arrangement
  • lubricant starvation when no regreasing interval is maintained
  • false brinelling from vibration while the shaft is stationary
  • fretting corrosion on a loose shaft seat

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.
  • Storage matters for open bearings: 6016-NSK leaves the factory with rust preventive only, so clean it and apply the service grease at assembly even if the rings look oily from the wrapper.
  • Open bearings tolerate the highest speeds in the 6000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6016 units.
  • Never mix components between two 6016-NSK units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
  • 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-NSK drags the lip and overheats it.
  • The open 6016 has no integral sealing; in the NSK E1103 catalogue the protected variants carry suffixes ZZ (non-contact steel shields), VV (non-contact rubber seals) and DDU (contact rubber seals). NSK does not offer a low-torque contact seal equivalent to NTN's LLH in this catalogue — for high-speed sealed duty specify the VV non-contact seal and an external housing labyrinth.
  • 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 6016 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.
  • 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.
  • 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.

Frequently asked questions

What are the dimensions of a 6016-NSK bearing?

A 6016-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 an open bearing with no seals or shields.

How should 6016-NSK be mounted?

Apply the mounting force to the ring being fitted: on a 80 mm shaft seat the press load must pass through the inner-ring face only. Induction heating of the inner ring (max 120 °C) is the clean method at this size. Never strike the outer ring, the cage or the seals.

What lubrication does 6016-NSK need?

The open 6016-NSK is lubricated by the application; a NLGI 2 lithium-soap grease filled to roughly 25–35% of the free volume is the common choice, with a defined relubrication interval.

What is the NSK order number for an open 6016?

NSK lists the open 6016 under the bare designation 6016; protected versions use suffixes ZZ (steel shields), VV (non-contact rubber seals) and DDU (contact rubber seals) on the same 80 mm bore envelope.

Does the manufacturing plant affect 6016?

NSK produces standard deep-groove sizes in several plants worldwide to the same drawing; the origin on the box label does not change the ISO 15 envelope or the E1103 catalogue ratings quoted here.
