Office Chair Wheel Lock

The common types and solutions for office chair wheel locks are as follows:

Wheels with Brake Locking Function

These wheels achieve locking and unlocking through mechanical structures. Their diameters are mostly 60 millimeters, and they are wrapped with soft PU material on the outer layer, ensuring durability while reducing wear on the floor. The locking method is manual operation: When fixing is required, push down the brake device on the wheel, and the part of the wheel in contact with the ground will be jammed, preventing the chair from moving; to unlock, pull up the brake device to restore the sliding function. A set usually contains 5 wheels, which can evenly distribute pressure, ensuring the stability of the chair in the locked state. This is suitable for office environments that require frequent switching between moving and fixed scenarios.

Gravity Self-Locking Wheels

Designed based on the weight-sensing principle, these wheels are equipped with a gravity-triggered mechanism inside. When the user sits on the chair, the wheels are pressed by gravity, and the internal mechanical structure (such as a spring or hydraulic device) automatically increases the resistance to the left and right rotation of the wheels, making the chair difficult to move; when the user gets up or lifts the chair, the gravity disappears, the lock is released, and the sliding function is restored. The advantage is that no manual operation is required, making them suitable for scenarios that require quick adaptation to different usage states, such as conference rooms or home office areas. However, it should be noted that people with lighter weights may not be able to trigger the lock, and after long-term use, the internal mechanism may experience reduced sensitivity due to wear.

Fixed Foot Pads

Achieve fixation by physically replacing the wheels: Pull out the original casters and insert the matching fixed foot pads (usually made of rubber or plastic), allowing the chair to be in direct contact with the ground and relying on friction to prevent displacement. The fixing effect is the most stable, suitable for scenarios with extremely high safety requirements, such as homes with elderly people or children or laboratories that need to remain absolutely still. However, it sacrifices mobility convenience, as the foot pads need to be removed and reinstalled each time the position is adjusted, and frequent insertion and removal may damage the wheel-axle interface of the chair.

Selection Advice: If both flexibility and fixity are required, prioritize wheels with brake locks or gravity self-locking wheels; if extremely high stability is required and no movement is needed, fixed foot pads are more suitable.
