Flexible Chain Corner Wheels

A flexible chain corner wheel is a driven turning unit used on flexible (modular) chain conveyors. It replaces the plain curve rail wherever the conveyor has to make a tight horizontal 90° or 180° loop, such as around machinery or in a compact layout.
It consists of a circular plate that cradles the chain, a curved aluminum guide track, and the wheel itself — normally made of 6063-T5 aluminum alloy with a nylon (plastic) contact face. The chain runs around the wheel, and the wheel positively drives and turns the chain instead of letting it slide through a passive bend.

Horizontal Curve Rails

Vertical Curve Rails

– It turns the flexible chain through 90° or 180° at a defined radius (e.g. R150 / R160 / R170), matching the chain width (63 / 83 / 103 mm series).
– It provides positive drive and tension, reducing chain wear, noise and slipping in the corner.
– The nylon face protects the chain and the conveyed products; aluminum keeps it light.
– It is installed together with horizontal/vertical curve rails to route the conveyor around corners, elevation changes and machines.

In short: it is the powered “pulley wheel” that bends and drives a flexible chain conveyor around tight 90°/180° corners.

Flexible Chain Curves & Corner Wheels
Q1: What is the difference between Horizontal Curve and Corner Wheel?
A: Horizontal Curve is a passive sliding curved rail. Corner Wheel is rotating powered turn unit with smaller turning radius, less chain wear and noise.
Q2: What does 45‑Series /65‑Series mean?
A: Series number matches flexible chain width. It is NOT the turning angle. Turning angles are 30°/45°/60°/90°.
Q3: What radii are available for Horizontal Curve?
A: Standard radii: R500, R700, R1000 mm. Some wide‑chain models only have R700 & R1000.
Q4: What is Vertical Curve used for?
A: For uphill & downhill elevation change of conveyor lines, multiple incline angles optional.
Q5: How to choose curve radius R?
A: Larger radius suits high‑speed / fragile goods; smaller radius saves installation space for low‑speed lines.
Q6: Does Corner Wheel need an independent motor?
A: No. It runs by main‑drive chain tension, no extra motor required.
Q7: Can custom‑size curves be made?
A: Custom radii & angles are acceptable, subject to MOQ requirement.
