KATO Hexatorq Hinges

KATO Hexatorq Hinges

Smooth. Constant. Torque.

Conventional spring type hinges can lose their stiffness and seize up to damage mating parts if used in high temperature environments or where excessive cycling increases the temperature inside the hinge.

KATO Hexatorq Hinges (KH) uses an innovative hexatorq design utilizing a modern engineered plastic resin which requires no lubrication. In fact, in an elevated temperature application, Hextorq hinges experience a predictable drop-off in torque, returning to original torque values after a minimal cool down period. This means no damage to your expensive part!

Hexatorq hinges are offered in standard sizes to meet virtually all common application requirements. We've done the testing for you! Our standard sizes and configurations were determined through extensive design, endurance testing and product validation. By utilizing KATO's Hexatorq hinges you can significantly reduce your typical design and manufacturing time.

KATO Hexatorq hinges come in two styles:

KATO Hexatorq Hinges With Brackets

With Brackets

(Left or Right Hand Mounting)

KATO Hexatorq Hinges Without Brackets

Without Brackets

Features & Benefits

  • Consistent torque, designed for 30,000 cycles or more without failure.
  • Smooth operation throughout a 360° range of motion.
  • Holds position throughout full range of motion, no spring-back.
  • Corrosion resistant stainless steel and engineered resin design.
  • Light-weight, compact, maximizing space, and weight saving.
  • Hex configuration provides for easy mold-in mounting without brackets.
  • No lubrication required! Eliminates the possibility of contamination and corrosion to sensitive parts.
  • FOD free design, no metal to metal friction means no foreign object damage from metal particles.

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.
