How the 16010 model number is decoded
In the 16000-series (the narrow extra-light section of ISO 15) the last two digits encode the bore: 16010 carries bore code 10 = 50 mm. Outside diameter 80 mm and width 10 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 50 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
- material-handling equipment
- industrial fans
- industrial electric motors
- centrifugal and positive-displacement pumps
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
- Temperature rise and interference fits consume internal clearance on this 50 mm bore: a CN bearing on a tight, hot shaft can lose all residual clearance — size 16010 with C3 for those conditions.
- Because the 160xx narrow section shares the 80 mm OD of the 6010 at 50 mm bore but is only 10 mm wide, a housing machined for the wider bearing needs a spacer or relocated circlip — never assume width interchangeability.
- The open 16010 has no lubricant retention: grease escapes and contaminants migrate straight into the 50×80×10 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 16010 units.
- Deep-groove ball bearings tolerate only minutes of misalignment; if the 80 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 16010.
- The housing bore for the 80 mm OD should be round within IT7; an oval bore pinches the outer ring of 16010 and shows up later as two-point loaded raceway wear.
- The open 16010 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.
- The 50 mm bore puts 16010 in NTN's general-purpose industrial range; the standard pressed-steel cage and CN clearance cover most electric-motor and pump duty, but for continuous high-speed use specify the LLH low-torque seal (not LLU) and confirm the housing allows the listed limiting speed.
- At 8400 r/min the grease limiting speed for 16010 covers most general-purpose industrial drives; the open or shielded execution can run continuously at this speed with standard lithium-soap grease.
- NTN rates 16010 at 14.7 kN dynamic (C) and 11.3 kN static (C0), 0.76 kN fatigue load limit Cu; this light-to-medium rating suits fractional-horsepower drives and instruments — for conveying or gearbox duty with shock loads, verify the equivalent dynamic load stays well below C.
- At 180 g, 16010 is light enough for hand assembly but should be pressed on with a fitting sleeve against the inner ring; do not strike the outer ring or cage with a hammer.
- The 50×80×10 mm envelope of 16010 gives a D/d ratio of 1.60 and 15.0 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 14.7/11.3 kN load ratings, 0.76 kN fatigue load limit Cu NTN lists the grease limiting speed at 8400 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 180 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16010 on the 50×80×10 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16010 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 16010 bearing?
A 16010 deep-groove ball bearing has a 50 mm bore, 80 mm outer diameter and 10 mm width (1.969 × 3.15 × 0.394 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 50 mm bore?
160 is the narrow extra-light section: 80×10 mm with a 15.0 mm radial section at 50 mm bore. It has the same bore and outside diameter as the 6010 but a narrower ring, so the two are not width-interchangeable; it appears in the manufacturer catalogues used on this site.
Are 16010 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 16010 uses the same ISO 15 envelope (50×80×10 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 16010?
NTN lists the open 16010 under the bare designation 16010; protected versions use suffixes ZZ (shields), LLB/LLF (non-contact seals), LLH (low-torque contact seal) and LLU (contact seal) on the same 50 mm bore envelope.
Is 16010 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.
