How the 16012 model number is decoded
16012 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the narrow 160xx section of the ISO 15 general plan, multiplying bore code 12 by five gives the 60 mm bore; the 95 mm outside diameter and 11 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 60 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
- 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
- false brinelling from vibration while the shaft is stationary
- fretting corrosion on a loose shaft seat
Selection pitfalls — read before you substitute
- Interference on a 60 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 16012 with C3 clearance and re-check the residual value after mounting.
- Because the 160xx narrow section shares the 95 mm OD of the 6012 at 60 mm bore but is only 11 mm wide, a housing machined for the wider bearing needs a spacer or relocated circlip — never assume width interchangeability.
- Storage matters for open bearings: 16012 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 16000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 16012 units.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 16012-C3. No clearance suffix means normal CN clearance.
- Never mix components between two 16012 units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
- The open 16012 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 60 mm bore 16012 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 7000 r/min the grease limiting speed for 16012 covers medium-duty industrial drives; the open or shielded execution can run continuously at this speed with standard lithium-soap grease.
- At 22.1 kN dynamic load rating (C) and 17.5 kN static (C0), 1.2 kN fatigue load limit Cu, 16012 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 283 g, 16012 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 60×95×11 mm envelope of 16012 gives a D/d ratio of 1.58 and 17.5 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 22.1/17.5 kN load ratings, 1.2 kN fatigue load limit Cu NTN lists the grease limiting speed at 7000 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 283 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16012 on the 60×95×11 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16012 in a rated drive.
- 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.
- Factory-fill grease in NTN sealed units is a general-duty lithium-soap grease; food-grade, low-temperature and high-temperature fills are request options at order time, because LLU/LLB units are not meant to be opened and re-greased in the field.
Frequently asked questions
What are the dimensions of a 16012 bearing?
A 16012 deep-groove ball bearing has a 60 mm bore, 95 mm outer diameter and 11 mm width (2.362 × 3.74 × 0.433 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
What lubrication does 16012 need?
The open 16012 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.
How does the 16012 bore code work?
The last two digits of 16012 are bore code 12, giving 12 × 5 = 60 mm bore. The 95 mm outside diameter and 11 mm width follow the ISO 15 diameter series, not the bore code alone.
What is the NTN order number for an open 16012?
NTN lists the open 16012 under the bare designation 16012; protected versions use suffixes ZZ (shields), LLB/LLF (non-contact seals), LLH (low-torque contact seal) and LLU (contact seal) on the same 60 mm bore envelope.
What cage does NTN fit in 16012?
Standard is a pressed-steel cage with no suffix; larger sizes or shock-loaded duty can be supplied with a machined brass cage (suffix M) as a separate order number. The catalogue figures quoted here are for the pressed-steel execution.
