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

Selection pitfalls — read before you substitute

• At 65 mm bore, induction heating to roughly 80–100 °C is the clean mounting method; never exceed 120 °C, and hold 16013 against the shaft shoulder while it cools so the ring cannot creep back.
• Because the 160xx narrow section shares the 100 mm OD of the 6013 at 65 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.
• 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.
• Measure the shaft, do not trust the drawing: a 65 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 16013.
• Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 11 mm-wide ring of 16013 drags the lip and overheats it.
• 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 (printed for some thin-section sizes) denotes a pressed-steel cage, not a seal.
• At 65 mm bore 16013 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 6500 r/min the grease limiting speed for 16013 covers medium-duty industrial drives; the open or shielded execution can run continuously at this speed with standard lithium-soap grease.
• At 22.7 kN dynamic load rating (C) and 18.7 kN static (C0), 1.26 kN fatigue load limit Cu, 16013 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 307 g, 16013 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 65×100×11 mm envelope of 16013 gives a D/d ratio of 1.54 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 22.7/18.7 kN load ratings, 1.26 kN fatigue load limit Cu NTN lists the grease limiting speed at 6500 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 307 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16013 on the 65×100×11 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16013 in a rated drive.
• Standard catalogue stock of 16013 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.
• 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.
