TSUBAKI

TSUBAKI is a Japanese manufacturer of power transmission and conveyor components, with a history dating back to 1917. The company is known for its extensive range of roller chains, conveyor chains, sprockets, and related accessories, serving industries such as material handling, automotive, food processing, and general manufacturing. TSUBAKI products are engineered to meet ANSI and ISO standards, with a focus on durability and precision. Key product families include standard and heavy-duty roller chains (e.g., ANSI 40, 50, 60, 80 series), attachment links (SK-1, SK-2), connecting links, and bushed-bore sprockets (e.g., 40BTL, 50BTL, 50SDS series). The company also offers keyless bushings (PL series) for shaft mounting without keyways. TSUBAKI components are typically constructed from carbon steel or nickel-plated steel, with options for coated chains in corrosive environments. Sprockets are available in various tooth counts (e.g., 22, 24, 48 teeth) and pitch diameters, with bore sizes accommodating standard bushing series like 1610. 3G Electric supplies over 1,300 TSUBAKI SKUs, including chains, sprockets, and locking assemblies, with datasheets and global logistics support. The product range covers inch-system dimensions for compatibility with North American equipment, as well as metric options. TSUBAKI's design specifications, such as pitch, tensile strength, and wear resistance, are documented in technical datasheets available through 3G Electric. The brand is widely used in conveyor systems, packaging machinery, and industrial drives where reliable power transmission is required. 3G Electric's inventory includes both standard and specialized TSUBAKI components, enabling procurement for maintenance, repair, and operations (MRO) as well as original equipment manufacturing (OEM) applications.

Frequently asked questions

Common questions about TSUBAKI from 3G Electric.

What ANSI chain sizes are available for TSUBAKI roller chains from 3G Electric?

3G Electric stocks TSUBAKI roller chains in ANSI sizes 40, 50, 60, and 80, with pitches ranging from 1/2 inch to 1 inch. These include standard, nickel-plated, and coated variants. For example, the 60NEPCL connecting link is for size 60 coated chain with a 3/4-inch pitch, while the 80NPSK1CL attachment link is for size 80 nickel-plated chain with a 1-inch pitch. All chains meet ANSI B29.1 standards for interchangeability.

How do TSUBAKI keyless bushings (PL series) work for shaft mounting?

TSUBAKI keyless bushings, such as the PL1G model, use a multi-screw locking assembly to secure components onto shafts without keyways. The bushing has a tapered design that expands when screws are tightened, creating a friction fit. The PL1G fits a 1 7/16-inch shaft diameter, with a 2 35/64-inch outer diameter and 0.787-inch width, made from carbon steel. This eliminates keyway stress risers and allows for precise axial positioning.

What sprocket options does TSUBAKI offer for size 50 chain?

TSUBAKI provides bushed-bore sprockets for size 50 chain in various tooth counts. Examples include the 50BTL48 with 48 teeth (9.566-inch pitch diameter) and the 50SDS22 with 22 teeth (4.392-inch pitch diameter). Both are steel and require a bushing series (e.g., 1610 for the 40BTL24). These sprockets are designed for ANSI 50 chain with a 5/8-inch pitch and are suitable for moderate to high-torque applications.

Are TSUBAKI connecting links compatible with heavy conveyor chains?

Yes, TSUBAKI offers connecting links specifically for heavy conveyor chains, such as the C2080H CONNECTING LINK. This steel link is designed for ANSI C2080 chain with a 2-inch pitch and is rated for heavy-duty applications. It provides a secure connection for conveyor systems handling bulk materials or heavy loads. Standard roller chain connecting links (e.g., 60CUCL for size 60) are also available for lighter duty.

What materials are used in TSUBAKI attachment links?

TSUBAKI attachment links, like the 80NPSK1CL, are typically made from nickel-plated steel for corrosion resistance, or carbon steel for standard applications. The SK-1 attachment style is a straight sidebar design for single-strand chains. These links are used to add fixtures or carriers to roller chains for conveying products. Material selection depends on environmental factors such as moisture or chemical exposure.

Does 3G Electric supply TSUBAKI products?

Yes — 3G Electric (S) Pte. Ltd. supplies TSUBAKI products. We stock the TSUBAKI catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
