How the 16026-NTN model number is decoded

In the 16000-series (the narrow extra-light section of ISO 15) the last two digits encode the bore: 16026 carries bore code 26 = 130 mm. Outside diameter 200 mm and width 22 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 130 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

• At 130 mm bore the ring mass is significant: heat 16026 on an induction heater (max 120 °C), never over an open flame, and plan puller access or a withdrawal sleeve now for the day it has to come off again.
• Because the 160xx narrow section shares the 200 mm OD of the 6026 at 130 mm bore but is only 22 mm wide, a housing machined for the wider bearing needs a spacer or relocated circlip — never assume width interchangeability.
• The open 16026-NTN has no lubricant retention: grease escapes and contaminants migrate straight into the 130×200×22 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 16026 units.
• Deep-groove ball bearings tolerate only minutes of misalignment; if the 200 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 16026-NTN.
• Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
• The open 16026 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 130 mm bore places 16026 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 3200 r/min for 16026; 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 88.5 kN dynamic load rating (C) and 79.5 kN static (C0), 4.25 kN fatigue load limit Cu, 16026 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 2310 g (2.3 kg), 16026 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 130×200×22 mm envelope of 16026 gives a D/d ratio of 1.54 and 35.0 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 88.5/79.5 kN load ratings, 4.25 kN fatigue load limit Cu NTN lists the grease limiting speed at 3200 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 2310 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16026 on the 130×200×22 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16026 in a rated drive.
• Standard catalogue stock of 16026 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.
• Two NTN bearings of the same designation from different production lots can carry minor internal-geometry revisions; for paired or preloaded arrangements on one shaft, order a single lot through the NTN distributor.
