Tsubaki Sprockets

Tsubaki sprockets are high-performance drive components engineered for precision, durability, and efficiency in industrial chain transmission systems. Designed for demanding environments in machine building, manufacturing, and processing plants, Tsubaki sprockets ensure smooth power transfer and long service life.

Tsubaki sprockets are designed to engage roller chains for the accurate transmission of rotational motion. Each sprocket is manufactured with high dimensional accuracy to match Tsubaki’s extensive chain range, ensuring perfect meshing and minimal wear.

The sprockets are available in a wide range of configurations — from standard pilot bore and finished bore types to hardened, coated, stainless steel, and engineering plastic versions. The precisely machined tooth profiles guarantee reliable torque transfer, reduced vibration, and optimized chain engagement.

Advantages and Features

  • Precision Engineering – Manufactured to tight tolerances for smooth and consistent chain engagement.
  • Hardened Tooth Options – Increased wear resistance for extended operating life.
  • Tough Tooth Technology – Reinforced tooth strength for use with high-strength chains such as Tsubaki’s G8 and Super-H Series.
  • Optional HV800 Coating – Special surface coating enhances tooth hardness and wear protection in harsh environments.
  • Material Flexibility – Available in carbon steel, stainless steel, and engineering plastic for different environmental and load requirements.
  • Custom Machining – Shaft bores, keyways, and tapped holes machined to specification.
  • Comprehensive Range – Sizes from RS40 to RS240, available in single, double, and multi-strand types.
  • Made-to-Order Options – Custom tooth counts, hub types, and shaft finishes available.
  • Maintenance Efficiency – Reduced replacement frequency and lower total cost of ownership.

FAQ – Tsubaki Sprockets

What is the difference between RS and BS/DIN sprockets?
RS sprockets are based on Japanese Industrial Standards (JIS), while BS/DIN sprockets follow European chain dimensions. Selecting the correct standard ensures perfect chain fit and performance.

What is “Tough Tooth” technology?
Tough Tooth sprockets feature hardened and optionally coated teeth with a Vickers hardness exceeding 800 HV, extending lifespan under heavy-duty or abrasive conditions.

Can Tsubaki sprockets be supplied with finished bores?
Yes. Bondy A/S offers in-house machining for custom bore diameters, keyways, and tapped holes to match your shaft design.

Which sprocket material is best for corrosive environments?
Stainless steel sprockets are recommended for chemical or washdown conditions. Engineering plastic types are suitable for light-duty and lubrication-free operation.
