Product Brief:
The B-604-BA-91-TE is a Kollmorgen B-series servo motor. “604” = frame size (160 mm outer diameter). “BA” = stack length variant (medium torque). “91” = shaft length code. “TE” = threaded shaft end (M10 × 1.0 tap) for direct encoder or coupling mounting.
Key Technical Specifications:

Material Composition:
- Stator: 0.35 mm silicon steel laminations, Class F copper windings
- Rotor: Sintered NdFeB permanent magnets, N42SH grade
- Housing: Anodized aluminum alloy (6061-T6)
- Shaft: Hardened stainless steel (AISI 420), ground to h6 tolerance
- Bearings: Double-sealed angular contact ball bearings (SKF/NSK equivalent)
Functional Features:
- Threaded shaft (M10 × 1.0) allows direct mounting of encoders, pulleys, or couplings without a separate hub
- High torque density: ~20 Nm/kg
- Low cogging torque for smooth low-speed operation
- Pre-balanced rotor for operation up to 5,000 RPM without vibration
Applicable Industries:
- Gantry systems
- Large-format printers
- Woodworking machines
- Metal cutting machines
- Heavy-duty conveyors
Installation Requirements:
- Mount using 4× M6 bolts on the Ø160 mm flange (bolt circle Ø130 mm)
- Shaft alignment tolerance: ≤ 0.05 mm TIR
- Maximum radial load: 200 N
- Maximum axial load: 100 N
Usage Notes:
- The TE (threaded) shaft requires a matching M10 threaded hub — do not use set-screw couplings on a threaded shaft
- IP65 rating requires the shaft seal to be installed; do not operate without it in wet environments
