KATO Suretorq Hinges

KATO Suretorq Hinges

High Performance Even After 50,000 Cycles.

KATO Suretorq hinges were developed to offer lightweight solutions for devices requiring position control and are manufactured using a high quality stainless steel body. Holding a given angle within design parameters, the Suretorq range shows a very small percentage drop-off in initial torque even when cycled in dual directions. At 50,000 cycles, Suretorq hinges show less than a 10% drop off in performance.

In order to assist customers reduce design and development cost, the entire standard range of sizes has been fully tested and inspected. For additional information contact KATO Tech-Group .

Suretorq hinges are suitable for a wide range of applications such as Notebook PC, Digital Cameras, Medical, and Dental devices.

KATO Suretorq hinges come in two ranges:

Suretorq ST010 - ST040 Range

ST010 - ST040 Range

(Left or Right Hand Mounting)

Suretorq ST060 - ST080 Range

Calculating Torque Requirement

Calculating Torque Requirement

Use the following formula: T = W x L x Cos(A)

Where:

A - Angle
L - Distance of Center of Gravity
T - Torque
W - Weight of Object to be Supported

Example:

W = 2 lbs. L= 4 in. Angle = 0°
T = (2) (4) Cos(0°)
T = 8lbf - in.

Notes:

1. If 2 Hinges are used: 8lb-in/2 = 4lb-in per Hinge.

2. To convert from lbf-in to kgf-mm, multiply by 11.5212.
