How the 16060 model number is decoded
In the 16000-series (the narrow extra-light section of ISO 15) the last two digits encode the bore: 16060 carries bore code 60 = 300 mm. Outside diameter 460 mm and width 50 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 300 mm shaft, typical catalogue practice is a m6 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
- medium and heavy industrial drives
- large gearboxes
- industrial fans and blowers
- hoists and winches
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
- Mount this 300 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 160xx narrow section at 300 mm bore shares the 460 mm outside diameter of the 6060 but is only 50 mm wide; a 6060 in a 50 mm-wide seat is loose axially and the reverse swap will not fit — match width as well as bore and outside diameter.
- The open 16060 has no lubricant retention: grease escapes and contaminants migrate straight into the 300×460×50 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 16060 units.
- Shaft and housing fillets must clear the bearing chamfer so the 50 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
- The open 16060 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 325/410 kN load ratings, 14.5 kN fatigue load limit Cu and 32500 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16060; 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 16060 bearing?
A 16060 deep-groove ball bearing has a 300 mm bore, 460 mm outer diameter and 50 mm width (11.811 × 18.11 × 1.969 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
How does the 16060 bore code work?
The last two digits of 16060 are bore code 60, giving 60 × 5 = 300 mm bore. The 460 mm outside diameter and 50 mm width follow the ISO 15 diameter series, not the bore code alone.
What does no suffix on 16060 mean?
A bare 16060 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 300 mm bore?
160 is the narrow extra-light section: 460×50 mm with a 80.0 mm radial section at 300 mm bore. It has the same bore and outside diameter as the 6060 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 16060?
In the NTN Ball and Roller Bearings catalogue (CAT.No.2203-3/E, 2024) this size is listed as 16060 — the open (unsealed) execution, 300×460×50 mm per ISO 15. Quoted values: C 325 kN, C0 410 kN, Cu 14.5 kN, mass 32500 g. Grease limiting speed 1300 rpm. The industry-neutral page spelling 16060 follows the seal-suffix convention used across this site, not NTN order-number spelling.
