Frequently Asked Questions - OK648-A Vevor

What is the required supply voltage?
The Vevor OK648-A linear actuator operates at a rated voltage of 12 V DC. Use a suitable 12 V DC power adapter.
What is the duty cycle of this actuator?
The duty cycle is 25%. This means it should not run continuously; for example, for 2 minutes of operation, allow 6 minutes of rest.
Is the actuator waterproof?
The protection rating is IP65, which protects against water splashes and dust. However, it is not fully waterproof: do not immerse it in water.
What is the maximum load the actuator can support?
The maximum rated load is 9000 N (approximately 917 kg). Be careful never to exceed this limit to avoid risk of damage or injury.
How to install the actuator correctly?
Install the actuator so that the load force is aligned with the center of the extension tube and the rear mounting adapter. Avoid lateral forces that could damage the unit.
Are there limit switches?
Yes, fixed limit switches (non-adjustable) are integrated. They automatically stop the motor when the tube is fully extended or retracted.
Why does the motor run slowly or lack power?
This may be due to insufficient power supply (voltage too low) or excessive load. Check the power supply and reduce the load if necessary.
What accessories are included with the actuator?
The kit includes 2 mounting brackets for easy installation. The power connector (female 6.3 mm type) is not included and must be chosen by the user.
In what types of applications can I use this actuator?
It is designed for uses such as hospital beds, electric sofas, adjustable desks, automotive and marine installations. Adjust the installation angle according to recommendations (100% thrust at 0°, 75% at 90°).
How to maintain and clean the actuator?
Disconnect the power supply before any maintenance. Clean with a dry cloth. Do not use harsh products. Cleaning and maintenance should not be carried out by children without supervision.

uitschuiven model OK628 résolu

bij het uitschuiven stop ik op een bepaalde hoogte, maar de actuator zakt gewoon.

Report this question
N Notice-Facile - 06/02/2026

Le problème que vous décrivez (l'actionneur redescend après un arrêt à mi-course) est courant avec les actionneurs linéaires sans frein mécanique intégré. Le Vevor OK648-A ne dispose pas de système de maintien de position automatique : une fois que vous arrêtez l'alimentation, la charge reprend son poids et l'actionneur redescend progressivement.

Les causes principales :

  • Charge trop proche de la limite – Si votre charge approche ou dépasse les 9000 N, le système ne peut pas maintenir la position sans alimentation continue. Vérifiez le poids exact supporté.
  • Arrêt avant les butées de fin de course – L'actionneur dispose d'interrupteurs de fin de course fixes. Si vous arrêtez manuellement avant ces points, il n'y a rien pour « verrouiller » la position.
  • Alimentation insuffisante – Une tension de 12 V trop faible peut réduire la force de maintien. Vérifiez votre alimentation.

Solutions pratiques :

  • Utilisez un contrôleur avec fonction de maintien (certains modèles gardent le moteur légèrement alimenté pour maintenir la position).
  • Installez un frein de charge supplémentaire (mécanique ou hydraulique) si le maintien est critique.
  • Réduisez la charge si elle approche les limites spécifiées.
  • Consultez la notice complète ou le SAV Vevor pour confirmer si ce modèle supporte une fonction de maintien.

IMPORTANT SAFEGUARDS

Vevor OK648-A - IMPORTANT SAFEGUARDS - 1

Please read and understand this entire manual before attempting to assemble, operate or install the product.

Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.

WARNING:

  1. The load added onto the actuator must be less than or equal to the rated load of the actuator.
  2. Install the actuator so the force of the load acts in the center of the extension tube and the rear mounting adapter.
  3. Use a 12V DC power adapter.
  4. All products have a working cycle and they cannot keep working non-stop.
  5. The linear actuator is not completely waterproof. Please do not immerse it directly in water.
  6. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

SAVE THESE INSTRUCTIONS

WARNING:

Changes or modifications to this product not expressly approved by the party responsible for compliance could void the user's authority to open the product.

Note:

This product generates, uses and can radiate radio frequency energy, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.

NOTE: please allow +5% tolerance due to manual measurement. This product is compatible with the corresponding female plus specifications (configured by the customer): 6.3MM 2P. Drawing6.3MM 2P Male, 6.3MM 2P Female.

Users should use caution to ensure that:

  1. The travel distance of the actuator satisfies the requirement of the structural design.
  2. The extended and retracted limit switches operate normally. The limit switches should stop the motor when the extension tube is fully retracted or fully extended.
  3. If the motor speed is too slow or it cannot provide sufficient power

(1) the power supply is insufficient and needs to be increased, or (2) the load being applied to the actuator is too great and needs to be reduced.

The linear drive is only responsible for the linear drive force.

  1. The loss caused by lateral and side forces cannot be estimated.
  2. The installation method produces a moment arm ratio.
  3. When the stroke exceeds 400 mm, the estimated value of the telescope tube's resistance to bending force and lateral force decreases.
