The elastic rubber wheel option provides a softer contact surface than harder wheel materials, helping absorb vibration when carts travel across floor joints, small bumps and slightly uneven surfaces.
This helps reduce impact transferred to:
The trolley or equipment
Goods being transported
Tools and instruments
The operator pushing the cart
Elastic rubber is particularly suitable for applications where smoother movement and operating comfort are important.
Compared with harder wheel materials, elastic rubber helps reduce rolling noise during regular trolley movement.
This makes the caster suitable for warehouses, workshops, service areas and other environments where carts are frequently moved by hand.
The compliant rubber surface reduces hard contact between the caster and the floor, making it a suitable option for facilities where floor protection needs to be considered together with load capacity.
Elastic rubber provides good contact with the floor and helps maintain stable movement during normal material handling operations.
Swivel Cross Section : Double ball bearings and double-track design enable higher load-bearing capacity and smoother rotation.

The swivel structure uses a double-ball-bearing and double-track design to support smooth rotation and directional changes.
This helps improve maneuverability when carts need to turn frequently in:
Warehouses
Production areas
Workshops
Storage areas
Logistics facilities
For equipment requiring different movement patterns, swivel, rigid and brake configurations can be selected according to the actual cart design.
This caster series is designed for equipment that may encounter moisture during normal industrial use.
The waterproof configuration improves suitability for:
Damp warehouse areas
Cleaning equipment
Utility carts
Service trolleys
Industrial environments subject to routine cleaning
For continuous washdown, chemical exposure, salt water or corrosive environments, please provide the actual working conditions so that the appropriate wheel material, bracket and mounting structure can be confirmed.
Different wheel materials provide different performance characteristics.
Recommended when the main priorities are:
Shock absorption
Quiet rolling
Floor protection
Comfortable manual operation
Better performance over minor floor irregularities
PU wheels can be considered when customers require a balance between rolling performance, durability and load handling.
PVC options may be suitable for general-purpose trolley and equipment applications depending on the operating environment.
PP wheels provide a harder rolling surface and may be suitable for applications where low deformation and easier rolling on smooth floors are important.
The final material should be selected according to the load, floor surface, operating environment and required service conditions.
This caster series is available in:
Orange

Langyi Elastic Rubber Waterproof Industrial Casters are suitable for:
Warehouse trolleys
Logistics carts
Material handling equipment
Workshop utility carts
Tool carts
Mobile workstations
Cleaning and service equipment
Storage and picking carts
Mobile racks
General industrial equipment
For specialized outdoor, food-processing, chemical or other demanding environments, the operating conditions should be confirmed before caster selection.
Choosing the correct caster requires more than checking wheel diameter.
Buyers should consider:
Include the weight of the trolley, machine or equipment itself.
Calculate the maximum expected goods or material load.
Confirm how many casters will support the equipment.
Consider whether the floor is:
Smooth epoxy
Concrete
Tile
Uneven
Fitted with joints or thresholds
Confirm whether the caster will be used in:
Dry indoor areas
Damp environments
Areas subject to cleaning
Outdoor conditions
Specialized industrial environments
Consider whether the equipment requires:
Swivel movement
Fixed direction
Brake function
Frequent turning
Caster capacity should not be calculated simply by multiplying the rated capacity of one caster by the number of wheels.
In actual use, loads may not be distributed evenly because of:
Uneven floors
Weight imbalance
Sudden direction changes
Impacts
Thresholds
Dynamic movement
A suitable safety margin should therefore be considered when selecting casters.
For a new trolley or equipment project, provide Langyi with:
Equipment weight
Maximum payload
Number of casters
Floor conditions
Required wheel size
This information helps determine a more appropriate caster configuration.
Elastic rubber is a good choice when the application places greater importance on:
Shock absorption
Low noise
Floor protection
Operator comfort
Smooth manual movement
Harder materials such as PP may be more suitable when easy rolling on smooth floors is a higher priority.
