How the UCP216 model number is decoded

The NTN UCP216 unit pairs a UC216D1 sealed ball bearing insert with a one-piece P216 cast-iron pillow block housing, delivered aligned, greased and ready to bolt down. The UCP216 number follows NTN's mounted-unit convention: housing letter P, 2-series section, bore code for 80 mm; P216 and UC216D1 are the separate housing and insert part numbers inside. Shaft size is 80 mm; the cast base stands 88.9 mm to the shaft centre (H), is 292 mm long overall (L), and the two foundation holes on 232 mm centres (J) clear 25 mm M20 bolts. 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 upright base carries the shaft parallel to and above the mounting surface, which is the arrangement fan, conveyor and transmission drives use whenever a plinth or rail is available. At 55–90 mm bore the units carry serious conveyor, fan and crusher-feed drives; housing stiffness, foundation condition and bolt torque matter as much as the insert rating. Quarry and aggregate conveyors specify this unit because maintenance crews can unbolt the whole assembly and swap it in minutes; interchangeability across brands at the JIS dimensions is part of the selection logic. Cold-climate users should order the low-temperature grease option or repack before commissioning: the factory fill is a general-purpose NLGI 2 that channels poorly below about −20 °C and starves the ball set on start-up. Basic ratings of the UC216D1 insert are 80.5 kN dynamic and 53 kN static; the assembled UCP216 weighs about 8.7 kg.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• UCP216 is located on the shaft by setscrews only; for shock reversing drives consider an adapter-lock insert family instead, since setscrew points indent the 80 mm journal over time.
• At 80 mm bore the 292 mm base of UCP216 is a structural member: grout or machine the foundation, because a bedded-on-edges housing concentrates the full belt pull on two cast feet.
• The standard 2-series insert in UCP216 is the lightest section at 80 mm — do not substitute it into a position that previously ran an X or 3 unit: the 232 mm mounting may match while the load rating does not.
• As a pillow block, UCP216 needs a prepared horizontal surface at the 88.9 mm centre height: shim both feet with full-width packs so the 292 mm base seats over its full area.
• At replacement time, measure the 80 mm shaft journal — a worn or deeply indented journal under the setscrews will let a brand-new UCP216 creep identically to the old one.
