The internal components of forklift wheels vary depending on the type of wheel
(such as drive wheels, steering wheels, load-bearing wheels, etc.) and specific design,
but typically include the following key parts:
1. Wheel Hub
The core supporting component of a wheel, usually installed on the axle through bearings,
is used to connect the wheel to the axle.The materials are mostly cast iron, steel or aluminum alloy.
2. Bearing (Bearings)
Ball bearings or tapered roller bearings: Reduce friction when the wheel rotates and ensure smooth
operation.Regular lubrication is required to prevent wear.
3. Rim
The metal outer ring of the fixed tire, in conjunction with the tire, forms a seal (for pneumatic tires)
or directly supports (for solid tire)
4. Components related to tire types
Pneumatic tire
Inner tubes (some are designed with and some are tubeless tires).
Valve stem: Used for inflation and deflation.
Solid tire
Solid rubber or polyurethane filling, without inner tube structure.
Cushioning tires: They have an elastic layer inside (such as a honeycomb structure), lying between
pneumatic and solid tires.
5. Seals
Oil seal: Prevents the leakage of lubricating grease and at the same time blocks dust and moisture from
entering the bearing.
6. Fasteners
Bolt/nut: Fixes the wheel hub to the axle or rim.
Retaining rings/retaining rings: Used for axial positioning of bearings or hubs.
7. Braking components (such as drive wheels)
Brake drums/brake discs: Some forklift drive wheels are integrated with braking systems.
Brake pads/shoe pads: Braking is achieved through friction.
8. Shock absorption components (for some models)
Rubber pads/springs: Used for shock-absorbing wheels (such as forklifts on uneven roads).
