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
- rolling-contact fatigue spalling after the rated L10 life is exceeded
- brinelling from static overload or hammering during mounting
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.
- The 160xx narrow section at 50 mm bore shares the 80 mm outside diameter of the 6010 but is only 10 mm wide; a 6010 in a 10 mm-wide seat is loose axially and the reverse swap will not fit — match width as well as bore and outside diameter.
- 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.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 16010-C3. No clearance suffix means normal CN clearance.
- 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 (as printed for some thin-section sizes) denotes a pressed-steel cage, not a seal.
- The 14.7/11.3 kN load ratings, 0.76 kN fatigue load limit Cu and 180 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16010; 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 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 16010 bore code work?
The last two digits of 16010 are bore code 10, giving 10 × 5 = 50 mm bore. The 80 mm outside diameter and 10 mm width follow the ISO 15 diameter series, not the bore code alone.
What does no suffix on 16010 mean?
A bare 16010 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 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.
What is the NTN designation and catalogue data for 16010?
In the NTN Ball and Roller Bearings catalogue (CAT.No.2203-3/E, 2024) this size is listed as 16010 — the open (unsealed) execution, 50×80×10 mm per ISO 15. Quoted values: C 14.7 kN, C0 11.3 kN, Cu 0.76 kN, mass 180 g. Grease limiting speed 8400 rpm. The industry-neutral page spelling 16010 follows the seal-suffix convention used across this site, not NTN order-number spelling.
