How the 16015 model number is decoded

16015 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 15 by five gives the 75 mm bore; the 115 mm outside diameter and 13 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 75 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

  • conveyor drives
  • material-handling equipment
  • industrial fans
  • industrial electric motors

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

  • Temperature rise and interference fits consume internal clearance on this 75 mm bore: a CN bearing on a tight, hot shaft can lose all residual clearance — size 16015 with C3 for those conditions.
  • The 160xx narrow section at 75 mm bore shares the 115 mm outside diameter of the 6015 but is only 13 mm wide; a 6015 in a 13 mm-wide seat is loose axially and the reverse swap will not fit — match width as well as bore and outside diameter.
  • The open 16015 has no lubricant retention: grease escapes and contaminants migrate straight into the 75×115×13 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 16015 units.
  • Shaft and housing fillets must clear the bearing chamfer so the 13 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
  • Grease compatibility is not guaranteed between fills: mixing lithium and polyurea thickeners in a 16000-series position can soften the mixture and leak — clean out the old fill before switching grease types.
  • The open 16015 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 75 mm bore 16015 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 5700 r/min the grease limiting speed for 16015 covers medium-duty industrial drives; the open or shielded execution can run continuously at this speed with standard lithium-soap grease.
  • At 27.6 kN dynamic load rating (C) and 24 kN static (C0), 1.6 kN fatigue load limit Cu, 16015 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 464 g, 16015 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 75×115×13 mm envelope of 16015 gives a D/d ratio of 1.53 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 27.6/24 kN load ratings, 1.6 kN fatigue load limit Cu NTN lists the grease limiting speed at 5700 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 464 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16015 on the 75×115×13 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16015 in a rated drive.
  • Standard catalogue stock of 16015 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.
  • 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.

Frequently asked questions

What are the dimensions of a 16015 bearing?

A 16015 deep-groove ball bearing has a 75 mm bore, 115 mm outer diameter and 13 mm width (2.953 × 4.528 × 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 75 mm bore?

160 is the narrow extra-light section: 115×13 mm with a 20.0 mm radial section at 75 mm bore. It has the same bore and outside diameter as the 6015 but a narrower ring, so the two are not width-interchangeable; it appears in the manufacturer catalogues used on this site.

Are 16015 bearings from different brands interchangeable?

For boundary dimensions, yes: every brand's 16015 uses the same ISO 15 envelope (75×115×13 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 16015?

NTN lists the open 16015 under the bare designation 16015; protected versions use suffixes ZZ (shields), LLB/LLF (non-contact seals), LLH (low-torque contact seal) and LLU (contact seal) on the same 75 mm bore envelope.

Is 16015 a current NTN production size?

The NTN 2203-series catalogue lists it as a standard size; availability of specific seal executions (ZZ, LLB/LLF, LLH, LLU) varies by region and stock — confirm with an NTN distributor before specifying spares.
