Torsion Springs Product Overview

♢ This series is MISUMI economy series Torsion Springs. It is manufactured in China, so its price is reduced significantly, up to 93% less than other similar MISUMI products.
♢ The torsion spring is a type of coil springs. The end of the torsion spring is fixed to other components. When other components rotate around the spring center, the spring will pull them back to the initial position to generate torque or rotation force.
It is used to control the movement of machine parts, alleviate impact or vibration, store energy, measure force, etc. It is widely used in computers, electronics, home appliances, cameras, instruments, doors, motorcycles, harvesters, automobiles and other industries.
The end of the spring can be wound into a hook-shaped or straight torsion arm.

Torsion Springs Product Features

♢ Torsion Springs It has complete specifications to satisfy requirements on various dimensions, torques and angles.
♢ Standard products right-hand wound are in stock and can be shipped next day after the order is placed, while the products left-hand wound can be shipped within 5 days after the order is placed.
♢ Alteration can be made to the length and bending in a short delivery time and small batches (shipping within 5 days for alteration to the length and 6 days for the alteration to the bending).
♢ The strength and service life can be guaranteed by using imported wire materials.
♢ The Torsion Springs is used to control the movement of machine parts, alleviate impact or vibration, store energy, measure force, etc. It is widely used in computers, electronics, home appliances, cameras, instruments, doors, motorcycles, harvesters, automobiles and other industries.

Torsion Springs Alteration

Torsion Springs Precautions

1. The Torsion Springs is prone to breakage if the pressure change exceeds the maximum value. The spring will break under high stress as the load curve rises due to the increase of the spring constant.
2. In applications without pre-twisting, the spring may be twisted due to vertical vibration caused by the gap. With pre-twisting, the spring works stably.
3. In applications where the spring is placed transversely, it may cause abrasion and breakage of the guide pin and spring.
