How the 16028 model number is decoded

In the 16000-series (the narrow extra-light section of ISO 15) the last two digits encode the bore: 16028 carries bore code 28 = 140 mm. Outside diameter 210 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 140 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 Schaeffler HR 1 catalogue this open execution carries the bare designation; protected variants are ordered separately with suffixes 2Z (steel shields), 2RZ (non-contact rubber seals) and 2RSR (lip-contact rubber seals).

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 140 mm bore the ring mass is significant: heat 16028 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.
• The 160xx narrow section at 140 mm bore shares the 210 mm outside diameter of the 6028 but is only 22 mm wide; a 6028 in a 22 mm-wide seat is loose axially and the reverse swap will not fit — match width as well as bore and outside diameter.
• The open 16028 has no lubricant retention: grease escapes and contaminants migrate straight into the 140×210×22 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 16028 units.
• Vibration during standstill brinells the raceways of a 140 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
• 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 16028 has no integral sealing; in the Schaeffler HR 1 catalogue the protected variants carry suffixes 2Z (two steel shields), 2RZ (two non-contact rubber seals) and 2RSR (two lip-contact rubber seals). Do not confuse FAG's 2RZ with a contact seal — the RZ lip does not touch the inner ring, which is why its speed capability stays close to the open bearing.
• FAG lists the mechanical limiting speed at 4400 r/min for 16028 (thermal reference speed 3200 r/min); the thermal reference speed is the binding figure for continuous duty — size the lubrication interval off the reference speed, not the mechanical limit.
• The 140 mm bore places 16028 at the lower end of Schaeffler's large-size range; at these diameters the pressed steel cage is speed-limited and FAG commonly offers a machined brass cage (suffix M) as an option. Verify cage material and relubrication provision with the distributor, and do not extrapolate small-bore speed ratings to this size.
• At 86 kN dynamic load rating (C) and 87 kN static (C0), 16028 is a heavy-load FAG bearing for industrial gearboxes and large conveyors; Schaeffler expects a machined brass cage (suffix M) at this rating for shock duty, and C0 must be checked against mounting or lifting loads.
• At 2540 g (2.5 kg), 16028 needs mechanical handling for mounting; Schaeffler recommends induction heating the inner ring (max 120 °C) rather than pressing cold, and a lifting provision if the housing is pre-assembled.
• The 140×210×22 mm envelope of 16028 gives a D/d ratio of 1.50 and 35.0 mm radial section height — a thin FAG section that saves space but is sensitive to misalignment and shock; keep the housing round within IT7 and the shaft deflection below the raceway contact envelope.
• The 86/87 kN load ratings, mass 2540 g here are Schaeffler HR 1 Rolling Bearings (Jan 2020) catalogue figures for 16028 on the 140×210×22 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16028 in a rated drive. Where FAG has since released an X-life version of this size, its expanded C/C0 ratings supersede the HR 1 print values quoted here.
• FAG standard tolerance for this size is P0 (PN); P6/P5 precision executions exist for spindle-adjacent duty but carry different order numbers in the Schaeffler system — they are not a selectable sorting of standard stock.
• For hot shafts above roughly 100 °C continuous, consult Schaeffler about seal material and grease options for the 2RSR execution of 16028; the standard NBR lip is the economical general-duty choice, not the high-temperature one.
