FEATURES

Key Features

01. Powertrain & Mechanical Integrity

High-Torque Powertrain

The Spartan SSB 52 and SSB 55 are engineered with heavy-duty power transmission systems for demanding spiral and circular rebar bending. The SSB 55 features dual 5 HP motors, delivering a combined 10 HP to handle high-tensile TMT steel up to Ø40 mm.

97% Efficient Planetary Gear Box

Features an outstanding planetary gear system that transmits 97% of the motor’s input energy directly to the bending rollers. This delivers massive torque, reduces load inertia, and maintains a smooth rotational speed of 9.04 RPM with zero gearbox jerks.

Maintenance-Free Synthetic Grease

Premium synthetic grease provides excellent thermal stability across varying site temperatures while eliminating periodic gear oil changes, oil leakage, and frequent lubrication maintenance.

Wear-Resistant Bending Components

Critical high-friction rollers feature Electroless Nickel Plating (ENP) for enhanced surface hardness, wear resistance, and corrosion protection, helping extend component life during continuous rebar processing.

02. Smart Setup & Precision Adjustments

Easy Spiral Diameter Adjustment

High-strength roller adjustment knobs allow operators to quickly change the distance between rollers, making it easy to produce different spiral and circular rebar diameters for varied project requirements.

Screw-Jacking Pitch Control

A dedicated screw-jack-driven pitch adjustment system enables accurate control of helical spiral pitch, helping achieve consistent spacing for piling cages and other reinforcement applications.

Integrated Dimension Scale

Built-in metric scales on the roller adjustment blocks support precise setup and repeatable positioning, reducing manual measurement errors and shortening machine setup time.

Faster Rebar Bending Setup

The combination of adjustable rollers, pitch control, and integrated measurement scales helps operators switch between different spiral sizes and project specifications more efficiently, improving rebar fabrication productivity on-site.

03. Rigorous Safety & Electrical Reliability

Siemens/Schneider Control Panel

The electrical panel is built using premium starters, relays, timers, and converters from globally recognized brands like Siemens and Schneider, preventing electrical failures under severe site voltage fluctuations.

Guarded Safe Foot Pedal

Bending strokes execute only when the foot pedal is kept pressed and halt instantly once released. To protect operators from dynamic hazards and falling concrete block impacts, the pedal is fully enclosed in a rugged steel foot guard cover.

Rust-Resistant ENP Plated Rollers

Bending and guide rollers undergo Electrodeless Nickel Plating (ENP), providing maximum surface hardness, wear resistance, and long-term protection against site rust and abrasive steel scale.

What is the maximum rebar diameter and spiral range that the SSB 55 can process?

The SSB 55 is Spartan's heavy-duty flagship circular bender. It is engineered to process heavy-duty rebar diameters ranging from Ø8 mm up to Ø40 mm for TMT and high-tensile steel grades (such as FE 550D). It can form spirals and circular rings with a minimum diameter of 250 mm (for Ø8 mm bars) up to a minimum of 800 mm (for Ø40 mm bars). The maximum processable spiral diameter can extend all the way up to 3 meters (3000 mm), making it highly versatile for piling cages of any scale.

How does the pitch adjustment system work for helical piling spirals?

Standard circular benders can only bend flat, single-plane rings. The SSB 55 features a specialized Pitch Adjustment Point with a Screw Jacking System. By turning the integrated manual screw jack, operators can easily raise or lower the pitch guiding block. This guides the rebar vertically during the bending cycle, creating a precise, consistent helical pitch for structural piling cages.

What is the advantage of the SSB 55's dual-motor powertrain over traditional benders?

Bending large-diameter rebar up to Ø40 mm into tight circular spirals requires massive, continuous bending force. Traditional single-motor benders often experience severe motor strain and speed drops, leading to inconsistent ring shapes. The SSB 55 uses a high-performance dual-motor system (5 HP / 3.7 kW x 2) delivering a combined 10 HP of bending force. This dual-power configuration, paired with a 97% efficient planetary gearbox, ensures constant rotational speeds of 9.04 RPM and smooth, deformation-free circular profiles without overloading the power grid.

Does the SSB 55 gearbox require regular gear oil changes?

No. Traditional gearboxes utilize conventional gear oil that leaks easily and requires constant site refilling and maintenance flushing. The SSB 55 is engineered with an advanced Grease-Lubricated Gearbox that completely eliminates leakages. It utilizes premium synthetic grease backed by a lifetime warranty, which maintains high thermal stability across hot and cold climates and never needs to be changed over the lifespan of the gearbox.

What safety mechanisms are built into the machine to protect our operators?

Operator safety is a foundational focus of Spartan's designs: Guarded Foot Pedal: Operation only occurs when the pedal is pressed down and stops instantly the moment the foot is removed. Steel Foot Guard Cover: A heavy-duty metal canopy encloses the pedal, preventing accidental activation from falling rebars, site debris, or worker slips. Housed Electrical limits: Top-brand limit switches are fully enclosed beneath the top plate to securely restrict mechanical travel.
