How the 16013 model number is decoded

In the 16000-series (the narrow extra-light section of ISO 15) the last two digits encode the bore: 16013 carries bore code 13 = 65 mm. Outside diameter 100 mm and width 11 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 65 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

  • centrifugal and positive-displacement pumps
  • gearboxes and speed reducers
  • conveyor drives
  • material-handling equipment

Known failure patterns

  • contamination wear from dust and dirt ingress through the open arrangement
  • lubricant starvation when no regreasing interval is maintained
  • fretting corrosion on a loose shaft seat
  • cage damage from operation beyond the limiting speed

Selection pitfalls — read before you substitute

  • Temperature rise and interference fits consume internal clearance on this 65 mm bore: a CN bearing on a tight, hot shaft can lose all residual clearance — size 16013 with C3 for those conditions.
  • The 160xx narrow section at 65 mm bore shares the 100 mm outside diameter of the 6013 but is only 11 mm wide; a 6013 in an 11 mm-wide seat is loose axially and the reverse swap will not fit — match width as well as bore and outside diameter.
  • The open 16013 has no lubricant retention: grease escapes and contaminants migrate straight into the 65×100×11 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 16013 units.
  • Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
  • The open 16013 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 (as printed for some thin-section sizes) denotes a pressed-steel cage, not a seal.
  • The 22.7/18.7 kN load ratings, 1.26 kN fatigue load limit Cu and 307 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16013; this seal/size combination has no counterpart from another catalogue on this site, so the page rests on a single manufacturer source — internal geometry and ratings legitimately differ between brands, so re-verify before substituting in a rated drive.

Frequently asked questions

What are the dimensions of a 16013 bearing?

A 16013 deep-groove ball bearing has a 65 mm bore, 100 mm outer diameter and 11 mm width (2.559 × 3.937 × 0.433 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.

How does the 16013 bore code work?

The last two digits of 16013 are bore code 13, giving 13 × 5 = 65 mm bore. The 100 mm outside diameter and 11 mm width follow the ISO 15 diameter series, not the bore code alone.

What does no suffix on 16013 mean?

A bare 16013 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 16000 compare with other series at the same 65 mm bore?

160 is the narrow extra-light section: 100×11 mm with a 17.5 mm radial section at 65 mm bore. It has the same bore and outside diameter as the 6013 but a narrower ring, so the two are not width-interchangeable; it appears in the manufacturer catalogues used on this site.

What is the NTN designation and catalogue data for 16013?

In the NTN Ball and Roller Bearings catalogue (CAT.No.2203-3/E, 2024) this size is listed as 16013 — the open (unsealed) execution, 65×100×11 mm per ISO 15. Quoted values: C 22.7 kN, C0 18.7 kN, Cu 1.26 kN, mass 307 g. Grease limiting speed 6500 rpm. The industry-neutral page spelling 16013 follows the seal-suffix convention used across this site, not NTN order-number spelling.
