Friction wear tester
TYPE: 40

Standard model of new friction and wear tester
Hop-up type acrylic cover that can be covered during measurement, newly developed orthogonal balance arm method, etc.
The birth of a new generation standard model of Tribo Gear.
Equipped with a Y-direction stage as standard, making testing easier.
Perform friction and wear tests comfortably with the Tribo Gear TYPE 40, which is easier to use and more accurate.


Newly developed “Orthogonal balance arm method” adopted. To higher measurement accuracy.

A load transducer that measures frictional force is placed directly above the stylus to eliminate unnecessary mechanisms and measure more directly.
This has eliminated high response and setting errors as much as possible.

In addition, the sliding direction of the sample table is orthogonal to the arm to eliminate load fluctuations on the outward and inbound routes.
Greatly improved the reliability of wear experiments.

Easy operation from software

Since it is operated by the touch panel, you can easily enter the measurement conditions.
In addition, a color liquid crystal panel is used so that the measurement operation status can be grasped at a glance.
If you use the optional tribo software, you can easily enter conditions, analyze, and even test operations from your computer.

Compatible with various JIS standards

By exchanging the attachment, it is possible to perform tests conforming to JIS K7125 (P8139) and P8147.

Large flip-up acrylic cover / simple sealing function
A large flip-up acrylic cover that can be used during testing is standard equipment.
As an option, the cover can be easily sealed to support tests in specific environments such as atmosphere and temperature.

Equipped with Y-direction stage as standard equipment

The “Orthogonal Balance Arm” is designed to stroke 13mm in the Y direction.
This makes it possible to measure another location without changing the sample as standard.

Real-time measurement of changes in frictional resistance due to wear

By repeating the friction of the reciprocating motion, the number of reciprocating movements in which the surface condition changes and the coating peels off is calculated from the increase or decrease in frictional resistance.
