How the 16020 model number is decoded

16020 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the narrow 160xx section of the ISO 15 general plan, multiplying bore code 20 by five gives the 100 mm bore; the 150 mm outside diameter and 16 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 100 mm shaft under normal load, catalogue practice seats it on a k5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. 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 100 mm of 16020 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.
• The 160xx narrow section at 100 mm bore shares the 150 mm outside diameter of the 6020 but is only 16 mm wide; a 6020 in a 16 mm-wide seat is loose axially and the reverse swap will not fit — match width as well as bore and outside diameter.
• The open 16020 has no lubricant retention: grease escapes and contaminants migrate straight into the 100×150×16 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
• Storage matters for open bearings: 16020 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 150 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 16020.
• Shaft and housing fillets must clear the bearing chamfer so the 16 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
• The open 16020 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.
• At 100 mm bore 16020 is in NTN's medium industrial range; the pressed-steel cage is standard but large-section 63xx/64xx sizes at this bore can be ordered with a machined brass cage (suffix M) for heavy-shock or very-low-speed duty — confirm cage material with the NTN channel if the application sees impact loads.
• NTN lists the grease limiting speed at 4200 r/min for 16020; 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.
• NTN rates 16020 at 39 kN dynamic (C) and 36.5 kN static (C0), 2.18 kN fatigue load limit Cu; this upper-medium rating covers conveyor and gearbox drives, but at these loads the pressed-steel cage can be the limiting factor under shock — consider the machined brass cage (suffix M) for impact duty.
• At 910 g, 16020 requires a soft-jaw vise or arbor press for mounting — never hammer it onto the shaft, and support the opposite ring to avoid brinelling the raceways.
• The 100×150×16 mm envelope of 16020 gives a D/d ratio of 1.50 and 25.0 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 39/36.5 kN load ratings, 2.18 kN fatigue load limit Cu NTN lists the grease limiting speed at 4200 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 910 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16020 on the 100×150×16 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16020 in a rated drive.
• 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.
• Standard catalogue stock of 16020 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.
