UCP Pillow Block Bearings

EP-UCP pillow block bearing units combine a set-screw insert bearing with a one-piece housing for straightforward shaft support. They suit conveyors, agricultural machinery, textile equipment and general rotating assemblies where the mounting surface runs parallel to the shaft.EP-UCP dimensional rangeUse shaft diameter first, then verify base spacing, centre height, mounting bolt size and available installation envelope. The table keeps the original metric values for the listed UCP models.ModelShaft d (mm)HLJANN1H1H0SBBoltInsertHousingMass (kg)EP-UCP2042033.3127963713191463.812.731M10EP-UC204EP-P2040.65EP-UCP2052536.51401053813191569.514.334.1M10EP-UC205EP-P2050.72EP-UCP2063042.9160121441721168215.938.1M12EP-UC206EP-P2061.15EP-UCP2073547.6167127451721179217.542.9M12EP-UC207EP-P2071.53EP-UCP2084049.218013752172118981949.2M12EP-UC208EP-P2081.88EP-UCP209455418914654172120105.51949.2M12EP-UC209EP-P2092.1EP-UCP2105057.220415959202521112.21951.6M16EP-UC210EP-P2102.5EP-UCP2115563.521717157202522124.522.255.6M16EP-UC211EP-P2113.3EP-UCP2126069.92381846620242413725.465.1M16EP-UC212EP-P2125.5EP-UCP2136576.22622036825302614925.465.1M20EP-UC213EP-P2135.6EP-UCP2147079.42662106925312715530.274.6M20EP-UC214EP-P2146.6EP-UCP2157582.627421773252928161.633.377.8M20EP-UC215EP-P2157.3EP-UCP2168088.92922327625303017433.382.6M20EP-UC216EP-P2168.3EP-UCP2178595.23102478325283218634.185.7M20EP-UC217EP-P21710.8EP-UCP21890101.63262628727323319839.796M22EP-UC218EP-P21813.0Selection notesFor replacement work, measure the shaft and the housing footprint before relying on a familiar series number. Set-screw locking is convenient on straight shafts; shock loading, frequent reversals or tapered-shaft arrangements may justify a different locking family.Common applicationsPillow blocks are widely used on conveyors, agricultural drives, fans, rollers and general machinery. Grease access, contamination, shaft alignment and surrounding guards should be checked at the machine level.Series and locking optionsFamilyConfigurationSelection contextEP-UCPSet-screw pillow blockStraight-shaft, two-bolt base mountingEP-NAPEccentric-lock pillow blockExisting eccentric-collar arrangements and shock-sensitive dutyEP-NAPK / EP-UCPKAlternate set-screw pillow block familiesMatch exact insert and housing geometryEP-UCPHHigh-centre pillow blockMachines that need extra shaft centre heightEP-UCPATapped-base pillow blockBolting from the underside / compact base arrangementsEP-UKP + HTapered-bore insert with adapter sleeveSleeve-mounted shafts where that system is specifiedHow to choose this categoryChoose a pillow block when the shaft runs parallel to a supporting base and a two-bolt foot fits the frame. Start with shaft diameter, then confirm centre height H, base length L, bolt spacing J, mounting-hole size and insert width. Locking method, contamination and relubrication access are separate decisions; they cannot be inferred from bore size alone.Typical applicationsCommon machine positions include conveyor pulleys, agricultural drive shafts, rollers, fans and general industrial supports. For heavy shock, wet crop environments or vibrating machines, include the actual duty and failure history in the RFQ so the locking and sealing approach can be reviewed.Frequently asked questionsWhat is the difference between EP-UCP and EP-NAP?EP-UCP is the set-screw pillow-block family; EP-NAP is an eccentric-collar family. Match the shaft, locking system and housing dimensions before changing between them.Can I select a pillow block by shaft diameter only?No. Centre height, bolt spacing, housing envelope, locking method, load and environment also need to match.What if my existing bearing has an inch bore?Provide the exact inch shaft diameter and complete current model, including any suffix. Do not round from a nearby metric size.Can I send a competitor model number?Yes, for identification and cross-reference. Final selection is confirmed from dimensions and machine interface.Related bearing-unit familiesAlso review EP-UC insert bearings for insert-only replacement, EP-UCF / EP-UCFL for face mounting and EP-UCT for adjustable conveyor take-up positions.Request a category quoteSend shaft diameter, mounting dimensions, locking method, application, quantity and any drawing or existing part number.
