Wheel conveyors Functions/Applications
Choosing a wheel conveyor
① Checking the products to be transported and the work environment
Check product conditions carefully since wheel conveyors are subject to more constraints than roller conveyors. Otherwise, the selection process is mostly the same as for roller conveyors.
① Product conditions
- Outer dimensions (length, width, height) and direction of flow
- Weight per item (if multiple types, maximum and minimum)
- Shape and construction of products (cardboard cases, plastic boxes, wooden crates, etc.)
- Condition of bottom surface (exercising caution with regard to cans and plastic cases)
② Transport volume conditions
- Will the conveyor be filled with products, or will there be spacing between products?
③ Work conditions
- Room temperature, high temperature, or low temperature?
- Moisture and humidity
④ Loading conditions
- How will products be placed on the conveyor?
② Choosing the width
First, choose the abacus-style conveyor width or Korocon Carrier wheel spacing based on the outer dimensions of the products being transported.
① Abacus-style conveyor
- Add at least 50 mm to the width of the bottom surface of the products being transported.
② Korocon Carrier
- To determine the wheel spacing, multiply the width of the bottom surface of the products being transported by 0.6 to 0.7.
- The wheel spacing can only be adjusted for straight installations. Curved installations cannot be adjusted.
- The width of products that can be transported within the wheel spacing adjustment range is between 160 and 750 mm.
③ Choosing a wheel model (Korocon Carrier)
Taking into consideration the wheel characteristics, choose a wheel model that suits the operating conditions. (Consider the wheel strength when using Korocon wheels with a non-standard frame.)
④ Choosing the wheel pitch
Choose the wheel pitch so that the products being transported are always supported by at least four wheels. Exercise care to ensure that the load on any given wheel does not exceed the allowable load.
⑤ Choosing the frame and leg pitch (Korocon Carrier)
On linear sections, there should be one leg every 1,800 mm. Intermediate legs are required on curved sections. For a more detailed indication of leg spacing, convert the product weight per meter using the chart to the right indicating the strength per two frame sections and choose a leg pitch so that the allowable load is not exceeded.

⑥ Choosing the slope (angle of incline)
The slope varies with factors such as the state of the bottom surface of the products being transported and their construction and weight. The chart to the right provides general guidance.

Wheel conveyor models and standard specifications
Since the PS, LS, SRS, and NTS models use the same greased bearings as driven models, they have somewhat higher rolling resistance values.

Part names
Abacus-style conveyor
FW = Frame inner width, W = Conveyor width (steel frame: W = FW + 60 aluminum frame: W = FW + 50), L = Conveyor length, H = Conveyor height, P = Wheel pitch, θ = Curve angle, Leg mounting holes (steel frame: ø9 aluminum frame: ø8.5)
Korocon Carrier
W1 = Frame inner width, L = Conveyor length, H = Conveyor height, P = Wheel pitch, θ = Curve angle, R = Curve radius, W1 = 115 (100), 230 (220), 340 (330), 450 (440) (Figures in parentheses apply to the OKR38BS.)
*The basic unit for Korocon Carrier models is one wheel row, but they are generally used with two wheel rows. Two- and three-row types incorporate an end base, and units with a length of 2,400 mm or longer also incorporate a center base.
