The SUCPA from NTN is a two-bolt flange housing that carries an insert bearing, made to hold a transmission shaft against a flat surface. It suits equipment where the support has to be compact and rigid, with straightforward alignment and fast installation. Shaft sizes and sealing arrangements vary across the series, so the full code matters when you order.
Reading the code helps you avoid ordering the wrong unit. SUCPA identifies the flange housing family with an insert bearing, and the digits that follow point to the shaft size, so SUCPA201, SUCPA202 and SUCPA203 sit at different shaft diameters in the same family. A hyphenated ending, such as SUCPA204-12 or SUCPA205-16, marks an inch-dimension version. With the complete part number in hand, the housing can be picked without guesswork.
Typical installations include conveyors, belts, agitators, blowers, centrifugal pumps, and machinery in food processing and agriculture. Food and beverage plants, chemical operations and water treatment equipment often use them because the two-bolt flange bolts easily to sheet metal or structural profile. Dryers and mills also use them where a shaft needs a stiff support that is simple to replace.
Selection comes down to shaft diameter, the type of load and where the unit will operate. Inserts are offered with a single seal or with an added radial shaft seal, so match the sealing to dust, moisture or washdown conditions. The flange must sit flat during mounting and the bolts should be drawn down evenly to keep the insert from distorting. Grease reaches the insert bearing through its built-in fitting, following the manufacturer's interval.
Housings with insert bearings from various brands can often be swapped when the shaft diameter, the spacing between flange holes and the center height line up. On a replacement job, verify those three dimensions plus how the insert locks onto the shaft. The main dimensions are enough to identify the part, and MR can point you to a suitable equivalent.

Frequently asked questions
- What does the hyphenated suffix mean in a SUCPA part number?
- A hyphenated ending such as SUCPA204-12 signals an inch shaft diameter version within the series. The main number gives the nominal size and the suffix the exact variant, so compare both the shaft diameter and the flange before ordering.
- How do I know if a SUCPA housing is compatible with my machine?
- Compare the shaft diameter, the distance between the flange holes and the center height. When those three match the original, compatibility is likely. If anything is unclear, send the part number or dimensions by WhatsApp and we will advise.
- What lubrication does a housing with insert bearing need?
- Grease is applied through the built-in fitting on the insert bearing. Use the grease the manufacturer recommends and follow your equipment's maintenance schedule. Where dust or humidity is present, inspect the sealing and lubricate more frequently.
