EP-NMRV-E030 Aluminium Coaxial Worm Gearbox — Overview
The EP-NMRV-E030 is a inline entry-level aluminium worm gearbox and the most compact inline unit in the NMRV-E coaxial series, built around a 030 mm worm gear centre distance. The defining characteristic of the NMRV-E series is its coaxial (inline) output configuration: unlike the standard NMRV030 where the output shaft exits at 90 degrees to the input, the NMRV-E030 has both the motor input and the output shaft on the same axis. This inline layout eliminates lateral shaft offset, enabling significantly more compact drive assemblies for small robotic actuators, compact conveyor drives, automation feeders, and inline pump drives. The unit retains the identical worm set, IEC-standard hollow bore input (56B5, 63B5, 63B14), and maximum output torque (200 Nm) as the right-angle NMRV030 — only the output direction changes. With die-cast aluminium A360 housing, IP65 shaft sealing, and 5–100:1 ratio range, the EP-NMRV-E030 is engineered for space-critical inline drive designs in light automation and robotics across Australia and international markets. All six mounting positions are supported, giving inline drive designers complete layout flexibility.

Core Features & Benefits
◯Coaxial Inline Output — Space-Saving Drive Layout
The defining feature of the EP-NMRV-E030: motor and output shaft aligned on the same axis. This eliminates the 90-degree lateral projection of a standard right-angle worm gearbox — reducing drive assembly width by up to 150 mm and enabling compact inline machine layouts in robotics, packaging, and conveyor applications.
△IEC-Standard Hollow Bore Input (56B5, 63B5, 63B14)
Hollow bore IEC input with motor flanges 56B5, 63B5, 63B14 allows direct motor mounting without adaptors. Compatible with standard AC motors, servo motors, and stepper motors — simplifying procurement and reducing commissioning time.
◆Corrosion-Resistant Die-Cast Aluminium Housing
A360 die-cast aluminium provides inherent corrosion resistance for food processing, pharmaceutical, coastal, and humid industrial environments — without the rust risk of cast iron. Smooth baked enamel surface is easy to clean in washdown zones.
■Identical Torque Rating to Right-Angle NMRV
The coaxial output configuration does not reduce torque capacity. The EP-NMRV-E030 delivers the same 200 Nm maximum output torque as the standard NMRV030, using the same precision-ground worm set and phosphor bronze wheel.
▶Six Mounting Positions — Full Orientation Flexibility
B3, B6, B7, B8, V5, and V6 mounting positions are all supported, enabling horizontal, vertical, and angled inline drive arrangements. The coaxial configuration is particularly effective in V5/V6 vertical orientations where a right-angle drive would require a 90-degree shaft offset fitting.
●Static Self-Locking at Ratios ≥ 40:1
At gear ratios of 40:1 and above, worm geometry provides static self-locking — preventing back-drive under static load without an external brake. This property is identical to the right-angle NMRV030 as the worm set is unchanged.
EP-NMRV-E030 (Coaxial) vs EP-NMRV030 (Right-Angle) — When to Choose Each
The NMRV-E030 and NMRV030 are mechanically equivalent units sharing the same worm set, torque ratings, and IEC input flanges. The only difference is output shaft direction. Use this table to determine which configuration suits your machine layout.
| Feature | EP-NMRV-E030 (Coaxial / Inline) | EP-NMRV030 (Right-Angle) |
|---|---|---|
| Output Direction | Coaxial / Inline — same axis as input | 90-degree right-angle to input |
| Drive Assembly Width | Narrower — no lateral shaft offset | Wider — output shaft projects laterally |
| Best Application | Inline drive layouts, compact machine frames | Right-angle drives, standard layouts |
| Output Torque | Up to 200 Nm (identical) | Up to 200 Nm (identical) |
| IEC Flange Input | 56B5, 63B5, 63B14 (same) | Same flanges (hollow bore IEC) |
| Double Output Shaft (DZ) | Not available (coaxial geometry) | Available (DZ suffix) |
| Housing Material | Die-cast aluminium A360 (same) | Die-cast aluminium A360 (same) |
| Weight | ~1.8 kg | ~1.8 kg (approx same) |
| IP Rating | IP65 standard (same) | IP65 standard (same) |
| Self-Locking | Identical — worm set unchanged | Identical — same worm set |

Selection Guide, Mounting Positions & Shaft Details
How to Select the Correct Ratio
- Calculate required output torque: M₂ = 9,550 × P (kW) / n₂ (rpm), multiplied by service factor (fs = 1.0–2.5).
- Find your ratio: i = n_motor / n_output. Select the closest available ratio from 5–100:1.
- Confirm torque capacity: The selected ratio’s rated torque must exceed M₂ × fs. If not, step up to EP-NMRV-E040.
- Note on coaxial layout: In the NMRV-E series the output shaft and motor shaft are coaxial. Ensure your machine layout can accommodate the longer axial assembly (motor + gearbox length along one axis) compared to the compact width of a right-angle unit.
Input & Output Shaft Details
Input: Hollow bore 9 / 11 mm | IEC flanges: 56B5, 63B5, 63B14 | Tolerance: H7
Output: Coaxial solid shaft 14 mm with keyway — on the same axis as the motor input shaft.
14 mm solid shaft with keyway, coaxial with input. Default supply.
Flanged coaxial output for direct bolt-on connection. Suffix: FL.
Double output shaft (DZ) is NOT available in the NMRV-E coaxial series due to the housing geometry.
Mounting Positions
| Position | Description | Shaft Orientation | Oil Level Note |
|---|---|---|---|
| B3 | Horizontal foot mount | Inline horizontal — motor behind, output in front | Standard fill level — default |
| B6 | Foot mount, output shaft down | Inline vertical downward | Reduce oil by ~15% |
| B7 | Foot mount, output shaft up | Inline vertical upward | Increase oil by ~15% |
| B8 | Foot mount, reversed | Inline horizontal reversed | Standard fill level |
| V5 | Flange mount, shaft down | Inline vertical downward | Reduce oil — see NMRV-E lube guide |
| V6 | Flange mount, shaft up | Inline vertical upward | Increase oil — see NMRV-E lube guide |
Important: For NMRV-E V5/V6 vertical mounting, use the NMRV-E lubrication diagram (not the standard NMRV diagram) to set the correct oil fill level, as the internal oil distribution differs in the coaxial configuration.
Frequently Asked Questions — EP-NMRV-E030
▶ What does the ‘E’ suffix mean in EP-NMRV-E030?
The ‘E’ suffix designates the coaxial (inline) output configuration. In the standard NMRV030, the output shaft is at 90 degrees to the input. In the NMRV-E030, both the motor input and the output shaft are on the same axis — making the unit significantly more compact in width for space-constrained machine layouts such as robotic actuators and inline conveyor drives.
▶ What are the input bore and IEC flange options for the EP-NMRV-E030?
The EP-NMRV-E030 features a hollow bore input accepting 9 mm and 11 mm motor shafts, with IEC motor flanges 56B5, 63B5, and 63B14. This supports direct mounting of standard fractional-horsepower AC motors, servo motors, and stepper motors up to 0.09 kW without separate adaptors.
▶ How much space does the inline layout save compared to the right-angle NMRV030?
The NMRV-E030 eliminates the 90-degree shaft offset of the standard NMRV, reducing the overall lateral width of the motor-gearbox assembly by approximately the full width of one housing face. In compact machine frames and robotic end-effectors where lateral space is limited, this can save 50–80 mm of total drive system width.
▶ What gear ratios are available for the EP-NMRV-E030?
The EP-NMRV-E030 offers the same 12 reduction ratios as the standard NMRV030: 5, 7.5, 10, 15, 20, 25, 30, 40, 50, 60, 80, and 100. Output torque and efficiency characteristics are identical to the NMRV030 — only the output shaft direction changes.
▶ Is the EP-NMRV-E030 suitable for servo motor integration?
Yes. The hollow bore IEC input and standard flange accept servo motor shafts with a matching adaptor kit. Please supply your servo motor output shaft diameter and flange dimensions at time of ordering. The coaxial layout is particularly popular for servo-driven positioning axes where a compact inline profile is required.
▶ What mounting positions does the EP-NMRV-E030 support?
The EP-NMRV-E030 supports all six standard NMRV positions: B3, B6, B7, B8, V5, and V6. In the inline configuration, the motor mounts axially behind the gearbox and the output shaft exits axially in front. All six orientations are available for wall, floor, or ceiling mounting.
