How the 16030-NTN model number is decoded

In the 16000-series (the narrow extra-light section of ISO 15) the last two digits encode the bore: 16030 carries bore code 30 = 150 mm. Outside diameter 225 mm and width 24 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 150 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

• Large bores like the 150 mm of 16030-NTN demand clean, burr-free seats; one raised burr under a ring this size cocks the bearing and concentrates load at the raceway edge, cutting life drastically.
• Because the 160xx narrow section shares the 225 mm OD of the 6030 at 150 mm bore but is only 24 mm wide, a housing machined for the wider bearing needs a spacer or relocated circlip — never assume width interchangeability.
• The open 16030-NTN has no lubricant retention: grease escapes and contaminants migrate straight into the 150×225×24 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
• Storage matters for open bearings: 16030-NTN 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.
• Deep-groove ball bearings tolerate only minutes of misalignment; if the 225 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 16030-NTN.
• Do not quieten a noisy bearing by preloading it: the 16000-series is a deep-groove design, not angular-contact; axial preload raises temperature and shortens grease life.
• The open 16030 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 150 mm bore places 16030 at the lower end of NTN's large-size range; at these diameters the pressed-steel cage is speed-limited and NTN commonly supplies a machined brass cage (suffix M) as an option. Verify cage material and relubrication interval with the NTN distributor, and do not extrapolate small-bore speed ratings to this size.
• NTN lists the grease limiting speed at 2800 r/min for 16030; this is a large or heavy-section size where centrifugal force and cage inertia cap the speed — for higher shaft speeds either step to a smaller bearing on the same bore or consult NTN for an oil-lubricated, machined-cage variant.
• At 107 kN dynamic load rating (C) and 101 kN static (C0), 5 kN fatigue load limit Cu, 16030 is a heavy-load bearing for industrial gearboxes and large conveyors; NTN expects a machined brass cage (suffix M) at this rating for shock duty, and the static C0 must be checked against any mounting or lifting loads.
• At 3070 g (3.1 kg), 16030 needs mechanical handling for mounting; NTN recommends induction heating the inner ring (max 120 °C) rather than pressing cold, and a lifting eye if the housing is pre-assembled.
• The 150×225×24 mm envelope of 16030 gives a D/d ratio of 1.50 and 37.5 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 107/101 kN load ratings, 5 kN fatigue load limit Cu NTN lists the grease limiting speed at 2800 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 3070 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16030 on the 150×225×24 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16030 in a rated drive.
• Order the C3 internal-clearance version (16030 with C3 after the seal code) when the shaft fit is tight or the shaft-to-housing temperature gradient exceeds roughly 10 °C — the residual clearance after mounting, not the catalogue CN figure, decides service life.
• Standard catalogue stock of 16030 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.
