How the 6016-NTN model number is decoded
6016 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. 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. In the NTN catalogue this open execution carries the bare designation; protected variants are ordered separately with suffixes ZZ (shields), LLB/LLF (non-contact seals), LLH (low-torque contact seal) and LLU (contact seal).
Typical equipment & failure modes
Common applications
- heavy conveyors
- pulp and paper machinery
- medium and heavy industrial drives
- large gearboxes
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
- Large bores like the 80 mm of 6016-NTN 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.
- 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.
- The open 6016-NTN has no lubricant retention: grease escapes and contaminants migrate straight into the 80×125×22 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- 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.
- 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.
- 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-NTN drags the lip and overheats it.
- The open 6016 has no integral sealing; in the NTN 2203 catalogue the protected variants carry suffixes ZZ (non-contact steel shields), LLB/LLF (non-contact rubber seals), LLU (contact rubber seals) and LLH (a low-torque contact seal with higher speed capability than LLU). A JR or JRX suffix (printed for some thin-section sizes) denotes a pressed-steel cage, not a seal.
- At 80 mm bore 6016 is in NTN'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 NTN channel if the application sees impact loads.
- At 5300 r/min the grease limiting speed for 6016 covers medium-duty industrial drives; the open or shielded execution can run continuously at this speed with standard lithium-soap grease.
- NTN rates 6016 at 53 kN dynamic (C) and 40 kN static (C0), 2.91 kN fatigue load limit Cu; 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 854 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 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 53/40 kN load ratings, 2.91 kN fatigue load limit Cu NTN lists the grease limiting speed at 5300 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 854 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E 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.
- Standard catalogue stock of 6016 is the general-purpose execution; for low-noise motor duty NTN offers low-torque seal and special-grease variants in this size class, which are separate order numbers.
- NTN date-codes its packaging; rotate stock first-in-first-out, because the grease inside sealed units ages on the shelf — after three to five years of storage, check the grease condition before putting the bearing into service.
Frequently asked questions
What are the dimensions of a 6016-NTN bearing?
A 6016-NTN 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.
What does no suffix on 6016 mean?
A bare 6016 designation means open: no shields or seals, normal CN radial clearance and P0 normal tolerance unless further suffixes are ordered. The application must supply and retain the lubrication.
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.
What is the NTN order number for an open 6016?
NTN lists the open 6016 under the bare designation 6016; protected versions use suffixes ZZ (shields), LLB/LLF (non-contact seals), LLH (low-torque contact seal) and LLU (contact seal) on the same 80 mm bore envelope.
Does NTN offer 6016 with C3 clearance?
Yes — most NTN deep-groove sizes can be ordered with C3 internal clearance (suffix C3 follows the seal code). C3 suits tight fits and hot shafts; for normal fits at moderate temperature the standard CN clearance of 6016 is the correct choice.
