Product Groups


Roller Chains

U.S. Tsubaki offers the widest variety of chains on the market including premium roller chain, self-lube LAMBDA series chain, corrosion-resistant Neptune chain, fatigue-resistant super chain, and our latest generation of high-quality, long-lasting ANSI chain.

The revolutionary Super Stainless chain is a unique product that combines the corrosion resistance and extreme temperature operating range of the 600 AS series stainless steel chain with the strength of ANSI carbon steel chain. These chains can replace carbon steel chain 1-for-1 and feature a higher side-bar waist and greater fatigue strength, as well as hardened pins and bushings.


Engineering Class Chain

U.S. Tsubaki offers heavy-duty engineered chain, designed to withstand rigorous operating conditions across a range of applications. Greater reliability, productivity, and wear life are attributes associated with Tsubaki’s engineered class product.


Power Transmission Components

U.S. Tsubaki power transmission parts portfolio includes: Shock Relays, Torque Limiters, Couplings, Gear Motors, and POWER- LOCK keyless locking devices.


Roller Chain Sprockets

U.S. Tsubaki fi­nished bore sprockets come with a keyway and two set screws as standard. Stock sprockets are made from 1045 cold rolled carbon steel and are black oxide coated for maximum corrosion resistance and durability. No powdered metal is used. All stock sprockets have hardened teeth to RC 35 – 50 standard on ANSI 35 – 80 pitch. This ensures long service life with minimal wear. All hard edges are chamfered and de-burred for the best ­fit.


Engineering Class Sprockets

U.S. Tsubaki sprockets for Engineering Class Chain are made with quality, heat-treated carbon steel, which provides long wear life, resists abrasion, and withstands heavy shock loads. Sprockets can also be manufactured using special materials such as alloy steel, stainless steel, or bronze to meet specific needs.


Other Sprockets

Smart Tooth sprockets with wear-indicator technology ensure maximum uptime and drive system efficiency by providing visual confi­rmation of excessive sprocket wear. Incorporating this patented technology into sprockets reduces overall system cost by offering predictable maintenance intervals to avoid catastrophic failure. Wear indicator technology is available on ANSI 100 through 240 pitch, and Engineering Class sprockets with pitch lengths greater than 4 in.


KabelSchlepp Cable and Hose Carriers

KabelSchlepp UST Tsubaki LogoTsubaki’s KabelSchlepp division has a proven history of technical excellence in developing products to address the challenges of managing, protecting, and guiding cables and hoses in motion applications.

  • Cable Types for Cable Carriers: Control, Power, Data, BUS, Coaxial, Fiber Optic, High Voltage, OEM, TRAXLINE

Cam Clutches

Tsubaki Cam Clutch (sprag style) products are designed to transmit torque in one direction of rotation, and overrun (freewheel) in the opposite direction of rotation. All utilize the same principles of operation. The three most common types of applications are:

  1. Backstopping: In backstop applications, clutches are used to prevent reverse rotation of drive shafts. With the outer race of the clutch anchored stationary, the inner race can overrun freely in one direction of rotation. Reverse rotation is prevented by the automatic engagement of the clutch. Typical backstop applications are in conveyor systems and gear reducers.
  2. Indexing: In this mode of operation, reciprocating motion applied to the driving race of the clutch is transformed into uni-directional intermittent motion at the driven race. For example, on a feeding roller, the clutch is mounted on the roller and a torque arm is connected to the driving race of the clutch.
  3. Overrunning: Clutches used in this type of application overrun at either the inner or outer race during the majority of the clutch operating time, and are occasionally called upon to lock up and drive. A typical application is a two-speed drive, where an electric motor and a geared motor are connected to a single driven shaft through one-way clutches.
