How the 16014 model number is decoded
In the 16000-series (the narrow extra-light section of ISO 15) the last two digits encode the bore: 16014 carries bore code 14 = 70 mm. Outside diameter 110 mm and width 13 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 70 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 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
- gearboxes and speed reducers
- conveyor drives
- material-handling equipment
- industrial fans
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- electrical pitting in VFD-driven motors without grounding protection
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- Interference on a 70 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 16014 with C3 clearance and re-check the residual value after mounting.
- Because the 160xx narrow section shares the 110 mm OD of the 6014 at 70 mm bore but is only 13 mm wide, a housing machined for the wider bearing needs a spacer or relocated circlip — never assume width interchangeability.
- The open 16014 has no lubricant retention: grease escapes and contaminants migrate straight into the 70×110×13 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 16000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 16014 units.
- Vibration during standstill brinells the raceways of a 70 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
- Never mix components between two 16014 units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
- The open 16014 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 70 mm bore 16014 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 6100 r/min the grease limiting speed for 16014 covers medium-duty industrial drives; the open or shielded execution can run continuously at this speed with standard lithium-soap grease.
- At 27 kN dynamic load rating (C) and 22.6 kN static (C0), 1.52 kN fatigue load limit Cu, 16014 is a medium-load bearing suitable for most electric-motor and pump duty; the C0/C0r ratio matters for preloaded or thrust-loaded arrangements, so confirm the static safety factor with the NTN catalogue.
- At 441 g, 16014 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 70×110×13 mm envelope of 16014 gives a D/d ratio of 1.57 and 20.0 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 27/22.6 kN load ratings, 1.52 kN fatigue load limit Cu NTN lists the grease limiting speed at 6100 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 441 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16014 on the 70×110×13 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16014 in a rated drive.
- Two NTN bearings of the same designation from different production lots can carry minor internal-geometry revisions; for paired or preloaded arrangements on one shaft, order a single lot through the NTN distributor.
- Order the C3 internal-clearance version (16014 with C3 after the seal code) when the shaft fit is tight or the shaft-to-housing temperature gradient exceeds roughly 10 °C — the residual clearance after mounting, not the catalogue CN figure, decides service life.
Frequently asked questions
What are the dimensions of a 16014 bearing?
A 16014 deep-groove ball bearing has a 70 mm bore, 110 mm outer diameter and 13 mm width (2.756 × 4.331 × 0.512 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
How does the 16000 compare with other series at the same 70 mm bore?
160 is the narrow extra-light section: 110×13 mm with a 20.0 mm radial section at 70 mm bore. It has the same bore and outside diameter as the 6014 but a narrower ring, so the two are not width-interchangeable; it appears in the manufacturer catalogues used on this site.
Are 16014 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 16014 uses the same ISO 15 envelope (70×110×13 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting.
What is the NTN order number for an open 16014?
NTN lists the open 16014 under the bare designation 16014; protected versions use suffixes ZZ (shields), LLB/LLF (non-contact seals), LLH (low-torque contact seal) and LLU (contact seal) on the same 70 mm bore envelope.
Does NTN offer 16014 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 16014 is the correct choice.
