Technical details

Standard stainless worm gearboxes: Assembly protection

Gearbox IP65; stainless motor IP66; assembled IP66 requires nitrile joint gasket

Stainless helical bevel gearboxes: series ratio / maximum torque

22: 4.83–70.24 / 50 Nm; 32: 7.33–77.55 / 90 Nm; 33: 7.33–324.18 / 100 Nm; 42: 7.29–77.36 / 150 Nm; 43: 7.29–323.37 / 150 Nm; ratios and torque limits belong to the named series and depend on configuration

Stainless helical bevel gearboxes: Dynamic efficiency

Up to 96% dynamic efficiency, depending on gearbox configuration

Stainless brake modules: Brake torque and motor frame

5 Nm: IEC 63/71; 10 Nm: IEC 80; 20 Nm: IEC 90

Stainless brake modules: Protection

IP68/69 when mounted between gearbox and motor; output shaft must not carry additional axial or radial loads

Electromagnetic clutches and brakes: torque range

7.5–480 Nm across seven sizes, depending on variant; 24 V DC

Incremental and absolute flange encoders: Incremental resolution

Up to 2048 pulses/revolution for incremental variants

Incremental and absolute flange encoders: Added drive length

Approximately 7–15 mm added drive length, depending on flange-encoder configuration

AEO authorisation: document dated 2017

AEO authorisation DK AEOF 16-1168671 names BJ-Gear A/S for customs simplifications and security/safety, effective 29 January 2017; current standing is unresolved.

Wind-electricity guarantees of origin: 2020

EWII guarantees of origin cover 100% of BJ-Gear’s estimated 2020 electricity consumption with Danish wind power; the statement applies to calendar 2020.

Stainless actuator construction and protection

AISI 304 stainless steel, IP69K configuration and FDA-approved sealing material; the sealing-material statement is not an approval of the complete actuator.

Supplied standard AC motor configuration

IP55 fully enclosed fan-cooled motors; insulation class F operated to class B temperature limits. Standard three-phase supply: 230/400 V ±10%, 50 Hz through 3 kW; 400/690 V ±10%, 50 Hz from 4 kW. Other voltages are order-dependent.

Supplied stainless AC motors

AISI 304 or AISI 316L; protection IP66–IP69K depending on configuration; TENV up to 0.75 kW or TEFC, with thermistors as standard.

Spring-applied brake variants

FDW: IP66; FDX: seawater-resistant IP67; FDS: IP65 holding brake with emergency-stop function. Standard IP54 applies when mounted under an electric motor fan cowl; variant selection determines protection.

Stainless levelling feet limits

Up to 10° slope and maximum 250 °C temperature for the described stainless levelling-foot range; available with or without fixing plate.
