How the UCFL202 model number is decoded

The NTN UCFL202 flanged unit combines a sealed UC202D1 insert with a diamond-shaped FL204 cast-iron housing that bolts flat against a machine frame. Reading the designation: UC marks the wide-inner-ring, setscrew-locking insert; FL marks the two-bolt rhombus flange housing; the 2 code identifies the duty series and the final two digits encode the 15 mm bore. Key mounting figures: flange height H = 113 mm, overall length L = 60 mm across the diamond, bolt centres J = 90 mm, and each ear takes a 12 mm (M10) fastener for the 15 mm shaft. The 2-series section is the standard-duty choice — the slimmest, lightest housing at this bore, selected when shaft speed and load are moderate and space is normal. The diamond flange carries the shaft square to a vertical face — a welded frame, side plate or gearbox wall — so no base plinth and no shim pack under the bearing are required. At 12–20 mm bore these are the light-drive units: small conveyors, packaging machines and appliance-grade equipment, where the cast housing is over-engineered relative to the load but forgiving of imperfect mounts. Small marine and dockside conveyors use this unit with stainless fasteners through the feet; the cast iron tolerates salt atmosphere far better than pressed-steel housings once paint is chipped. In wet or washdown positions, orient the grease fitting at 45° and purge after every wash; water trapped between the slinger and lip seal emulsifies the grease even when the unit is sealed. Basic ratings of the UC202D1 insert are 14.2 kN dynamic and 6.65 kN static; the assembled UCFL202 weighs about 0.5 kg.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 15 mm bore the unit is cheap but the shaft is slender: a bent or undersized shaft, not the bearing, is the usual failure cause for UCFL202, so check journal straightness before fitting.
• The standard 2-series insert in UCFL202 is the lightest section at 15 mm — do not substitute it into a position that previously ran an X or 3 unit: the 90 mm mounting may match while the load rating does not.
• As a rhombus flange, UCFL202 pulls against the frame through only two M10 bolts on 90 mm centres; the mounting plate must be stiff enough not to bend between them under belt load.
• At replacement time, measure the 15 mm shaft journal — a worn or deeply indented journal under the setscrews will let a brand-new UCFL202 creep identically to the old one.
• UCFL202 is located on the shaft by setscrews only; for shock reversing drives consider an adapter-lock insert family instead, since setscrew points indent the 15 mm journal over time.
