H-Series helical gearbox - heavy parallel shaft

Capability Highlights

1 to 4 gear stages delivering nominal torque from 3,300 to 1,400,000 Nm
Flender H-Series exact dimensional and performance interchange
Advanced thermal management including enveloping air fans and cooling coils
Direct full-complement cylindrical roller bearings for maximum life

Typical Applications

Bulk material handling and long belt conveyors
Heavy-duty bucket elevators and hoists
Paper machine press roll drives
Extruder and mixer main drives

Engineering Focus

Nominal torque (T2N) vs application demand torque
Thermal capacity rating without external cooling
Output shaft configurations (solid, hollow with shrink disc, splined)
Horizontal vs vertical mounting oil level and sealing arrangements

Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Nominal Torque Range	3,300 to 1,400,000 Nm	Provides the sheer mechanical strength required to drive multi-ton industrial loads continuously.
Ratio Range	i = 1.25 to 450	Covers everything from high-speed pump drives to ultra-slow kiln rotations.

H parallel shaft helical gearbox	Heavy parallel-shaft helical reducers for conveyors, mixers, crushers, and large process equipment.	torque 3,300-1,400,000 Nm ratio 1.25-450 parallel shaft arrangement	Use this family when the drive train needs a Flender or SEW-style horizontal parallel-shaft replacement.
Heavy conveyor and hoist package	Drive packages with backstop, brake, fan, cooler, and shaft accessory review.	backstop or brake option thermal power check service factor review	Use this family when accessories and duty cycle determine whether a replacement is reliable.
Custom shaft arrangement	Solid shaft, hollow shaft, shrink-disc, and foot/flange mounting adaptations for legacy equipment.	shaft height match mounting foot pattern solid or hollow output	Use this family when the gearbox must match an existing foundation and connected machine shaft.

RFQ Checklist

Provide incumbent model code (e.g., Flender H3SH12)
Specify motor power, input speed, and exact required ratio
Define output shaft type (e.g., hollow shaft with shrink disc)
List required accessories (fan, heater, PT100, backstop)

Risk Controls

Thermal overheating in dusty environments: We offer optimized fan cowlings and external oil coolers for applications exceeding thermal nominal limits.
Shaft misalignment causing bearing failure: We supply precision motor swing bases, fluid couplings, and rigid couplings to protect the input/output shafts.
