\u2605 IP67 \u2014 Unique in the Korea Ever-Power Inline Precision Range<\/div>\n

EP-AE is the only inline series<\/strong> in the Korea Ever-Power precision planetary gearbox range where IP67 full-submersion protection (1 metre depth, 30 minutes) is available as an upgrade option. All other inline precision series are limited to IP65. If your application involves continuous water immersion, high-pressure steam cleaning, or direct spray at close range, EP-AE with IP67 is the specified choice.<\/p>\n<\/div>\n

The EP-AE series large-flange planetary gearbox<\/strong> combines two structural advantages in one product: an oversized output flange<\/strong> whose outer diameter extends beyond the gearbox body to resist overturning moments at the machine interface, and the option to upgrade to IP67<\/strong> water-submersion protection \u2014 a combination available nowhere else in the Korea Ever-Power inline planetary range. Seven frame sizes from EP-AE050 to EP-AE235 cover 14 N\u00b7m to 2,000 N\u00b7m with \u226597% single-stage efficiency and a \u221210 \u00b0C to +90 \u00b0C operating range.<\/p>\n

The backlash specification is \u22648 arcmin single-stage<\/strong> \u0438 \u226412 arcmin two-stage<\/strong> \u2014 a fixed value with no P0\/P1\/P2 grade selection. This positions EP-AE as the choice for applications where sub-5-arcminute positioning precision is not the primary specification, but where the flange interface must carry significant structural load, the environment is wet or wash-prone, and the \u226597% efficiency and \u221210 to +90 \u00b0C range<\/strong> of the precision family are still required. A compact EP-AES variant<\/strong> extends the same specification to four smaller frames (050S\u2013120S) covering up to 330 N\u00b7m for lighter-duty large-flange applications.<\/p>\n

When IP65 is Not Enough \u2014 and EP-AE IP67 Solves It<\/h3>\n
\n
\n

Food and Beverage CIP Washdown<\/strong><\/p>\n

Clean-in-place (CIP) systems in Korean food and beverage manufacturing direct high-pressure hot water \u2014 sometimes with caustic cleaning agents \u2014 directly onto installed machinery, including gearbox housings. IP65 protects against water jets but not against submersion or sustained low-pressure flooding that can occur when cleaning water pools around machinery bases. IP67 covers this condition: 30 minutes at 1 m depth means even a drive unit sitting in a pooled cleaning solution after washdown is fully protected. Korean food manufacturers with HACCP or FSSC 22000 certification often require an IP67 planetary gearbox<\/strong> in documented machine specifications.<\/p>\n<\/div>\n

\n

Outdoor Installation in Korean Monsoon Season<\/strong><\/p>\n

Korean monsoon rainfall (jangma) delivers sustained high-intensity rain over weeks in July\u2013August. Outdoor machinery \u2014 agricultural automation, environmental treatment equipment, port and logistics systems \u2014 can experience standing water accumulation around drive units during extreme rainfall events. IP65 protects against rain water jets; IP67 provides the additional margin for equipment that may intermittently sit in accumulated water. For Korean OEMs designing outdoor systems to a 25-year service life specification, IP67 eliminates a failure mode that IP65 leaves open.<\/p>\n<\/div>\n

\n

Pharmaceutical and Semiconductor Wet Processes<\/strong><\/p>\n

Pharmaceutical and semiconductor facilities use deionised water and chemical rinse cycles that can deposit liquid on drive units in close proximity to process chambers. IP67 provides the assurance that even direct contact with rinse water or brief submersion in a process spill does not cause water ingress into the gearbox. For Korean semiconductor OEMs building equipment to SEMI standards and Korean pharmaceutical manufacturers building to GMP, the IP67 certification provides documentation support for machine qualification.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\nIP67 is a factory-specified option, not a field modification. Specify IP67 at the time of ordering by including the protection level in your EP-AE part number request. Korea Ever-Power will confirm the IP67 surcharge and any lead-time difference. IP67 cannot be retrofitted to an IP65 unit in the field \u2014 the sealing geometry must be built into the unit at manufacture.<\/span><\/div>\n<\/section>\n

\n

When a cantilevered load \u2014 a heavy rotary table workpiece, a robot arm, or a spindle head \u2014 applies a force perpendicular to the output shaft axis, it creates a bending couple at the large flange planetary gearbox<\/strong> output interface. The mounting bolts on the tension side must resist this overturning moment; their effectiveness scales linearly with the bolt-circle radius. EP-AE’s oversized flange extends this radius well beyond the gearbox body diameter, dramatically increasing the structural capacity of the mounting interface without any change to the gear train.<\/p>\n

\n

AES selection tip:<\/strong> Choose AES when the machine requires the large-flange structural interface but the output torque fits within 330 N\u00b7m and a smaller overall gearbox footprint is needed. The AES is not simply a de-rated AE \u2014 it is a physically smaller unit with the same large-flange proportion relative to its body size.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\u25b8 No P0\/P1\/P2 grade selection in EP-AE: <\/span>
\nUnlike EP-AB which offers three selectable backlash grades, EP-AE has a single fixed backlash specification: \u22648 arcmin single-stage, \u226412 arcmin two-stage. There is no option to order P0 or P1 precision in the EP-AE series. If your application requires tighter than \u22648 arcmin, the correct product is EP-AB (for standard-flange) or, if you need the large-flange geometry, consult Korea Ever-Power \u2014 custom specifications may be available for high-volume applications.<\/span><\/div>\n<\/section>\n

Applications \u2014 Where Large Flange and IP67 Define the Selection<\/h2>\n

\"Planetary<\/p>\n

\n
\n
\n

Food Processing Lines \u2014 IP67 and Large Flange Combined<\/h3>\n

Korean food processing equipment \u2014 poultry processing, meat cutting, seafood handling, ready-meal manufacturing \u2014 is subject to HACCP-mandated daily hot-water and chemical washdown at pressures that can cause water pooling around drive units. The combination of EP-AE’s large flange (for the structural demands of carrying heavy conveyor loads and wash-resistant housings) with the IP67 option (for submersion-proof sealing during cleaning) addresses both the mechanical and environmental requirements of these applications in a single product. EP-AE090 and EP-AE120 at ratios 15:1\u201350:1 cover the majority of Korean food processing conveyor and portion-line drive requirements. Compatible with precision CV drive shafts for offset conveyor configurations.<\/p>\n<\/div>\n

\n

Heavy Rotary Tables \u2014 Large Flange for Overturning Moment<\/h3>\n

Heavy rotary tables in Korean metal forming, welding fixture, and assembly line applications carry large workpieces at offset positions \u2014 generating overturning moments at the table drive flange. Where the application does not require sub-5-arcminute servo precision \u2014 simple indexing, manual or pneumatic locking between positions, or slow continuous rotation \u2014 EP-AE delivers the large-flange structural capacity at \u22648 arcmin positioning performance at a cost-appropriate specification. EP-AE155 and EP-AE205 at 20:1\u201350:1 cover heavy industrial rotary table applications with output torques up to 2,000 N\u00b7m.<\/p>\n<\/div>\n

\n

Outdoor Environmental Systems \u2014 IP67, \u221210 to +90 \u00b0C<\/h3>\n

Korean wastewater treatment plants, environmental monitoring stations, outdoor aquaculture feeding systems, and port equipment all combine outdoor exposure with mechanical loads that benefit from a wider-than-standard flange interface. EP-AE with IP67 covers the submersion risk of equipment in flooding-prone outdoor locations \u2014 a relevant specification for Korean coastal and riverine industrial sites. The \u221210 to +90 \u00b0C range handles both Korean winter outdoor conditions and warm-season process temperatures without special lubrication. Downstream integration with self-locking worm stages provides gravity-load holding for vertical outdoor drives.<\/p>\n<\/div>\n<\/div>\n
