Our Range Of Inline Geared Helical Unit

Looking for Inline Geared Helical Units & Motors? At Engineers Mate, we stock and supply a comprehensive range of industrial Inline Geared Helical Units. Designed for continuous-duty, high-torque, and energy-efficient applications, these gearmotors feature a coaxial configuration where the motor shaft and gearbox output align on the exact same axis.

Whether retrofitting an existing conveyor, replacing a failed drive on a production line, or specifying components for an OEM machinery project, our technical team provides instant access to premium inline helical gear units from globally recognised brands including Varvel, TEC, and Bonfiglioli.

Key Engineering Benefits & Operational Advantages

Maximum Operating Efficiency: Delivering up to 98% mechanical efficiency per gear stage, inline helical gearboxes minimise power loss to friction, substantially reducing energy costs and heat accumulation during continuous 24/7 duty cycles.
Superior Torque & Load Capacity: Precision-machined, hardened helical gear teeth distribute stress across a larger surface area, providing excellent resistance to heavy shock loads and high operational torque requirements (up to 18,000 Nm).
Ultra-Quiet Running Dynamics: Gradual tooth meshing absorbs vibrational energy and acoustic resonance, delivering whisper-quiet, low-decibel performance essential for enclosed processing areas and noise-sensitive plants.

Coaxial In-Line Footprint: Aligning the input motor shaft directly with the output shaft creates a compact, streamlined footprint ideal for straight-line drive installations along conveyor lines and machinery frames.

Technical Specifications & Stock Profile

Rugged Housing Construction: Available in lightweight, corrosion-resistant die-cast aluminium for smaller power demands and heavy-duty cast iron monobloc frames for high-vibration, harsh industrial environments.
Output Shaft Configurations: Stocked in metric standard single solid output shafts with precision keyways, as well as extended, double, or custom-machined shaft dimensions.
Broad Performance Capabilities: Available in power ratings up to 90kW and output speeds ranging from 0.6 RPM to 1,115 RPM.
Motor Coupling & Electrical Options: Direct-coupled or IEC flange-adapted to 230V single phase and 400V three-phase motors, with compatibility for ATEX-rated units, electric brake motors, and inverter-duty setups.
Flexible Mounting Options: Fully adaptable across foot-mounted (B3), output flange-mounted (B5 / B14), or universal combination foot/flange setups for seamless installation into existing machinery frames.

Typical Industrial Applications
Inline helical geared units are widely specified across UK industry for:

Materials Handling & Conveyors: Smooth power transmission for belt, roller, and chain conveyors.
Mixers, Agitators & Pumps: High starting torque for viscous fluids and continuous fluid movement.
Processing & Packaging Machinery: Reliable performance in indexing, lifting, and automated production line drives.
