\u2605 IP67 \u2014 The Only Right-Angle Series in the Korea Ever-Power Precision Range with Submersion Protection<\/div>\n

EP-ABR and EP-ADR are limited to IP65. EP-AER is the only right-angle planetary gearbox series in the Korea Ever-Power precision range where IP67 full-submersion protection (1 m depth, 30 minutes) is available as an upgrade option. For washdown environments, outdoor installations, and food-processing right-angle drives, EP-AER is the only right-angle product that provides this protection level.<\/p>\n<\/div>\n

The EP-AER series right-angle large-flange planetary gearbox<\/strong> is the direct 90-degree version of the EP-AE inline large-flange series<\/a>, adding a right-angle output direction change while preserving all three of EP-AE’s defining characteristics: the oversized large flange<\/strong> whose outer diameter extends beyond the gearbox body for high overturning moment resistance, the IP67 upgrade option<\/strong> available on no other right-angle series in the precision range, and the fixed \u22648 arcmin single-stage backlash<\/strong> specification without P0\/P1\/P2 grade selection. Seven frame sizes from EP-AER050 to EP-AER235 cover 14 N\u00b7m to 2,000 N\u00b7m output torque with \u226597% single-stage efficiency and \u221210 \u00b0C to +90 \u00b0C operating range.<\/p>\n

The EP-AERS compact variant<\/strong> extends the same large-flange right-angle IP67 specification to four smaller frames (050S\u2013120S) covering up to 330 N\u00b7m, for applications requiring the same interface and environmental properties in smaller installed dimensions.<\/p>\n

Large Flange + Right-Angle + IP67 \u2014 Three Properties That Define the EP-AER Application<\/h2>\n
\n

<\/p>\n

\n
\n
\n
\ud83d\udca7<\/span> IP67 at the Right-Angle Output \u2014 Food Processing and Washdown<\/strong><\/div>\n

In food and beverage processing lines where the right-angle drive unit must survive CIP (clean-in-place) high-pressure steam washing and pooled water accumulation around the machine base, IP65 provides water-jet protection but not sustained submersion protection. EP-AER with IP67 covers 30 minutes at 1 m depth \u2014 protecting the right-angle drive unit during all standard Korean food-plant HACCP washdown cycles, including the pooled-water accumulation phase that exceeds IP65 protection.<\/p>\n<\/div>\n

\n
\ud83d\udd32<\/span> Large Flange at the Right-Angle Output \u2014 Overturning Moment Resistance<\/strong><\/div>\n

When a right-angle gearbox drives a load that applies an overturning moment at the output flange \u2014 a heavy conveyor head, an arm mechanism, a rotary positioner with offset workpiece \u2014 the large flange’s extended bolt-circle radius resists this moment through a greater number of bolts at a greater radius. In right-angle configurations this matters particularly because the motor and gearbox assembly creates an additional moment arm: EP-AER’s large flange carries both the driven-side structural load and the assembly weight moment.<\/p>\n<\/div>\n

\n
\ud83d\udd04<\/span> Right-Angle Output \u2014 Motor Perpendicular to Driven Axis<\/strong><\/div>\n

For Korean food processing, outdoor equipment, and washdown-environment machines where the servo or induction motor must be positioned perpendicular to the output axis \u2014 motor inside a protected enclosure alongside the machine, output shaft running through a sealed wall into a wet or outdoor zone \u2014 EP-AER’s right-angle output separates the motor from the load environment. Combined with IP67 sealing on the right-angle gearbox itself, the motor remains in a dry protected space while the gearbox output is fully exposed to the wet environment.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\u25b8 When the right-angle drive must be IP67: <\/span> EP-AER is the only available option among right-angle precision planetary gearboxes in the Korea Ever-Power range. If IP67 is not required and sub-5 arcmin backlash is, use EP-ABR or EP-ADR with the appropriate P0\/P1 grade. If both IP67 and right-angle output are required, EP-AER is the sole solution \u2014 with the trade-off that backlash is fixed at \u22648 arcmin (no P0\/P1 tighter option available).<\/span><\/div>\n<\/section>\n

Applications \u2014 Right-Angle Large-Flange IP67 in Korean Industry<\/h2>\n

\"planetary<\/p>\n

\n
\n

Food Processing Right-Angle Conveyor Heads \u2014 IP67<\/h3>\n

Korean food processing lines \u2014 poultry and seafood conveyor transfer heads, filling station drives, CIP-compatible accumulation conveyors \u2014 require right-angle drives where the motor is positioned perpendicular to the conveyor belt axis (motor inside a dry protected cabinet, output shaft through a sealed bulkhead into the wet conveyor zone). EP-AER with IP67 handles the continuous CIP washdown, steam-cleaning, and pooled water that occurs in these zones. The large flange carries the conveyor belt tension overturning moment at the transfer head without bolt-face fretting. AER090 and AER120 at ratios 20\u201350 cover the most common Korean food-line conveyor head torque ranges.<\/p>\n<\/div>\n

\n

Outdoor Wastewater Treatment \u2014 Large Flange, IP67, Right-Angle<\/h3>\n

Korean wastewater treatment plant aeration and agitator systems use horizontal motors driving vertical agitator shafts \u2014 a 90-degree direction change through the tank wall. The right-angle drive unit sits at the tank top, exposed to splashing and accumulated water. EP-AER IP67 protects against the coastal spray and monsoon rain accumulation that exceeds IP65 protection in outdoor Korean treatment plant environments. The large flange carries the agitator shaft overturning moment from fluid resistance. AER120 and AER155 at ratios 25\u201350 cover most Korean wastewater agitator drive torque requirements. Pairs with self-locking worm reducers for additional speed reduction and gravity holding on power failure.<\/p>\n<\/div>\n

\n

Heavy Rotary Table Side Drive \u2014 Large Flange Right-Angle<\/h3>\n

Korean heavy industrial rotary tables \u2014 steel billet handling, large fixture rotation, welding turntable systems \u2014 where the table drive motor cannot be positioned below or behind the table (floor-mounted with motor inside the base, output shaft driving the table from the side) use a right-angle drive. The large flange of EP-AER carries the combined overturning moment from the table workpiece weight and the motor-gearbox assembly cantilever, without the bolt-face micro-fretting that occurs at a standard flange under these combined loads. AER155 and AER205 at ratios 20\u201350 cover the torque range for Korean heavy industrial side-entry table drives.<\/p>\n<\/div>\n

\n

Pharmaceutical Clean Room \u2014 IP67 Right-Angle Drives<\/h3>\n

Korean pharmaceutical equipment requiring right-angle drives in process zones subject to spray cleaning, deionised water rinsing, and occasional submersion-level cleaning specifies IP67 for the drive unit. EP-AER with IP67 documents the required protection level for GMP machine qualification audits in Korean pharmaceutical manufacturing facilities. The large flange’s structural interface supports the moment loads from mixing paddles, bottle transfer arms, and conveyor heads in a single sealed, IP67-certified housing. AER070 and AER090 at ratios 15\u201335 cover most Korean pharmaceutical process drive torque requirements.<\/p>\n<\/div>\n

\n

Agricultural Machinery Right-Angle Drives \u2014 AERS Compact<\/h3>\n

Korean precision agriculture seeder and spreader mechanisms where the drive shaft must turn a corner to reach a working head mounted at 90 degrees to the drive motor axis use EP-AERS (050S\u2013120S, up to 330 N\u00b7m) for compact right-angle large-flange installations. The IP65 standard sealing is suitable for outdoor agricultural exposure; IP67 can be specified for equipment installed in flood-prone field conditions or subject to regular pressure washing. Downstream agricultural bevel gearboxes distribute the AERS output to multiple seeder heads from a single right-angle drive unit.<\/p>\n<\/div>\n

\n

Marine and Port Equipment \u2014 IP67 Large Flange<\/h3>\n

Korean port and marine equipment \u2014 dock leveller actuators, mooring equipment, shipyard positioning fixtures \u2014 combines outdoor coastal spray exposure, occasional standing water, and large moment loads at the drive output. EP-AER IP67 at AER205 and AER235 delivers the large-flange structural capacity for heavy port loads with the full-submersion protection required for equipment installed at tidal height where temporary immersion at dockside is possible. The right-angle output allows the motor to be positioned in a protected dry housing while the gearbox output shaft faces the exposed marine environment. Pairs with CV joint drive shafts for offset load connections in port equipment installations.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
