XT40-1-E-MB Enhanced Spindle Head (Rear-Mounted)
XT40-1-E-MB places the motor toward the rear of the enhanced XT40-1 spindle platform. Confirm the rear envelope, center height, belt path, guarding and service access before the assembly is released.
- Spindle interfaceNT40-E / BT40
- Published speed2,500 / 4,500 / 7,000 rpm (NSK option)
- Assembly reference35 kg spindle head; assembly weight is drawing dependent
- Published accuracy≤ 0.004 mm roundness
Send the operation, workpiece, tooling, target speed, load, duty cycle and machine interface drawing for configuration review.
Final specifications depend on the workpiece, tooling, cutting load, duty cycle, motor and machine interface.
XT40-1-E-MB rear-mounted layout
A rear-mounted motor arrangement for the XT40-1-E platform, selected around rear clearance, belt routing and maintenance access.
XT40-1-E-MB places the motor toward the rear of the enhanced XT40-1 spindle platform. Confirm the rear envelope, center height, belt path, guarding and service access before the assembly is released.
Application fit
Start with the workpiece and process. The model name is only a starting point; final selection follows the tooling, load and real machine layout.
Rear-clearance layouts
Use the rear-mounted arrangement when the machine structure provides a controlled rear service zone.
Modular machining units
Integrate the spindle, motor and belt package with a slide, column or special-purpose frame.
Guarded belt drives
Plan the belt path, guard, tensioning method and inspection access into the machine design.
Retrofit upgrades
Compare center height and rear projection against the existing power-head mounting.
Published selection data
| Model platform | XT40-1 enhanced boring and milling spindle head |
|---|---|
| Spindle interfaces | NT40-E or BT40, selected around the tool interface and change method |
| Published speed options | 2,500 rpm, 4,500 rpm and 7,000 rpm NSK-bearing option are shown in the published parameter data |
| Bearing arrangement | 2,500 rpm: NN3011/234411BM1 with 7010AC/DB; 4,500 rpm and the 7,000 rpm NSK-bearing option: 7011AC/TBT with 7010AC/DB |
| Lubrication | High-speed bearing grease |
| Published temperature rise | ≤ 20°C under the conditions represented by the published data |
| Published roundness | ≤ 0.004 mm; confirm measurement point, method and acceptance conditions |
| Published maximum power | ≤ 10 HP |
| Three-phase motor reference | 1.5–4 kW; 2-pole 3,000 rpm, 4-pole 1,500 rpm or 6-pole 1,000 rpm listed |
| Servo spindle motor reference | 1.5–5.5 kW; 2,000 rpm rated and 7,000 rpm maximum listed |
| Motor arrangement | Rear-mounted motor (MB) |
| Integration file | Request the matching dimensional drawing and compatible 3D file before integration |
| Layout check | Rear projection, belt routing, motor clearance and maintenance access must be confirmed from the selected drawing |
MB identifies the rear-mounted layout, not a universal motor or assembly weight. The spindle-head reference is 35 kg; motor, pulley, guard and accessory weight must be confirmed for the final build.

XT40-1-E-MB selection questions
Confirm these items before the drawing and quotation are approved.
Which spindle interface should I specify for XT40-1-E-MB?
Start from the tool interface, cutting load, tool-change method and required accuracy. Send the tool specification and operation so the complete spindle configuration can be checked.
Are all published speed values available on every configuration?
No. The drawings show configuration-dependent speed options. The approved limit depends on the spindle, bearings, motor, drive ratio, cutting load and duty cycle, so the final value must be confirmed in the quotation and drawing.
What does the rear-mounted motor (mb) arrangement change?
The rear-mounted motor (mb) arrangement changes the motor envelope, belt path, guarding and service access. Compare the matching drawing with the machine envelope before fixing the mounting position.
Can JNYO provide a dimensional drawing or 3D model?
Dimensional and compatible 3D files can be requested for integration review. Include the spindle interface, motor arrangement and tool-change requirements so the matching file is selected.
What information is needed for a quotation?
Send the workpiece material, operation, tool details, target speed, cutting load, accuracy requirement, machine interface drawing, motor preference, quantity and destination country.
Catalog source and configuration limits
JNYO product catalog, printed pages 13–14 (PDF page 10); Chinese edition, approximately 74 MB.
Spindle speed and motor speed are separate values; output speed depends on the selected drive ratio and complete configuration. Catalog roundness and temperature rise require defined measurement and operating conditions and are not guarantees of workpiece accuracy. HP and kW retain the source units.
NT40 rear-drawbar and BT40 automatic tool-change arrangements are shown separately. ATC does not by itself include through-spindle coolant; CTS also requires compatible tooling, a coolant passage, rotary union, supply, filtration and control interfaces.
Move from product review to machine integration.
Use the model as a starting point. The approved dimensional drawing and configuration record remain the final integration reference.
Confirm mounting faces, center height, spindle interface and machine envelope.
