Industrial Wheels — The Key Component of Warehouse and Production Equipment

The design of industrial wheels directly affects the maneuverability of carts and platforms, the safety of personnel, and the overall efficiency of in-house logistics.

The Benefits of Choosing the Right Wheels:

Equipment Mobility.
Easy movement of carts, racks, machines, and tooling.

Reduced Physical Strain.
Less effort required from operators, minimizing the risk of musculoskeletal injuries.

Safety and Floor Protection.
Controlled starting and braking, no slipping, and no damage to floor surfaces.

Reduced Downtime.
Durable components, predictable wear, and quick maintenance ensure continuous operation.

Types of Wheels and Castors

Swivel Castors — Free Maneuvering and On-the-Spot Rotation

Allow smooth steering and easy rotation in any direction.

Fixed Castors — Stability for Straight and Long-Distance Movement

Ensure precise tracking and stability when moving in a straight line or over long paths.

Combination Trolleys — 2 Swivel + 2 Fixed Castors for Balanced Control

Provide an ideal balance between directional stability and maneuverability.

With Brake — Wheel and/or Swivel Locking

Equipped with wheel and/or swivel locks, selected according to operating conditions.

Wheel Tread Materials

Elastic Rubber — Smooth running, low noise, and gentle on floors; medium wear resistance.

Polyurethane (PU) — High durability, low rolling resistance, and excellent floor protection; optimal for intensive use and heavy loads.

Nylon / Polyamide — Minimal rolling resistance, excellent chemical resistance, and high hygiene; may produce more noise on hard floors.

Cast Iron / Steel — Designed for heavy loads and high temperatures; require strong flooring and generate increased noise.

Types of Wheel Bearings

Plain Bearing (Bushing) — Simple and cost-effective; suitable for low speeds and intermittent operation.

Roller Bearings — Higher load capacity at a moderate price.

Ball Bearings — Minimal rolling resistance for long-term continuous operation.

Wheel Mounting Types

Top Plate Mounting (4-Bolt Fixing) — The standard for industrial trolleys; the dimensions of the plate and the bolt hole spacing are critical.

Bolt Hole Mounting — Designed for light-duty and transport equipment.

Stem Mounting — Used for stands, medical, and laboratory furniture.

How to Choose — A Quick Checklist

Load Capacity.
Calculate using the formula:
Wheel load capacity ≥ (weight of the load + weight of the trolley) / number of castors × safety factor (typically 1.3–1.5).

Floor Surface.
Hard / even — PU or nylon; delicate — rubber or soft PU; thresholds or uneven surfaces — choose a larger diameter.

Environment.
Moisture, oils, chemicals, temperature, or clean-room conditions — choose the appropriate wheel tread material and bearing type accordingly.

Operating Mode.
For long travel distances, speeds above 4–6 km/h, or continuous multi-shift operation — prioritize ball bearings and wear-resistant treads.

Maneuverability.
The layout of movement routes determines the proportion of swivel castors and the type of brakes required.

Noise.
For office, medical, or night-shift environments — choose rubber or soft PU wheels with a cushioned tread.

Common Mistakes

Selecting by wheel diameter only, without considering load capacity or floor surface conditions.

Saving on bearings when operating continuously or under heavy use.

No load capacity margin for thresholds, ramps, or impact loads.

Ignoring temperature or chemical exposure, which leads to premature wear and failure.

Maintenance and Service Life

Maintenance and Service Life

Regularly check the fastenings, tread wear, and swivel head play.

Lubricate the bearings if they are serviceable.

Keep the wheel tread clean — abrasive debris accelerates wear.
