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

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.
• Because the 160xx narrow section shares the 460 mm OD of the 6060 at 300 mm bore but is only 50 mm wide, a housing machined for the wider bearing needs a spacer or relocated circlip — never assume width interchangeability.
• 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.
• Storage matters for open bearings: 16060 leaves the factory with rust preventive only, so clean it and apply the service grease at assembly even if the rings look oily from the wrapper.
• Measure the shaft, do not trust the drawing: a 300 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 16060.
• Suffixes stack in a defined order — clearance follows the seal code, e.g. 16060-C3. No clearance suffix means normal CN clearance.
• 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 (printed for some thin-section sizes) denotes a pressed-steel cage, not a seal.
• The 300 mm bore places 16060 in NTN's extra-large range; the pressed-steel cage is not recommended at this diameter and NTN supplies a machined brass cage (suffix M) as the standard offering. Speed ratings are low, housing alignment is critical, and oil lubrication with a defined relubrication interval is mandatory — consult NTN engineering before sizing.
• NTN lists the grease limiting speed at 1300 r/min for 16060; this is a large-section size where the pressed-steel cage is speed-limited — NTN recommends the machined brass cage (suffix M) and oil lubrication for any continuous operation above this figure.
• NTN rates 16060 at 325 kN dynamic (C) and 410 kN static (C0), 14.5 kN fatigue load limit Cu; this is an upper heavy-load rating where the pressed-steel cage is not recommended — NTN supplies a machined brass cage (suffix M) and the static C0 must be verified against any shock or lifting loads the bearing sees during mounting.
• At 32500 g (32.5 kg), 16060 is a very heavy bearing where handling and mounting method directly affect service life; NTN requires induction heating of the inner ring (max 120 °C), a mechanical puller for removal, and a defined lifting procedure to avoid damaging the machined brass cage.
• The 300×460×50 mm envelope of 16060 gives a D/d ratio of 1.53 and 80.0 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 325/410 kN load ratings, 14.5 kN fatigue load limit Cu NTN lists the grease limiting speed at 1300 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 32500 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16060 on the 300×460×50 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16060 in a rated drive.
• 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.
• 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.
