The Head Pulley Tail Pulley are not merely isolated components but a coordinated assembly for the conveyor's end drives. From the drive-end power transmission to the tail-end return guidance, the two must be designed in unison-regarding diameter, bearing center distance, shaft tolerances, and lagging configuration-to ensure the belt tracks in a straight line from head to tail. We supply them as a complete set, processed in the same batch, inspected to the same standards, and shipped together. Simply provide the installation dimensions of your existing conveyor, and we will manufacture the pulleys to spec; they are ready for immediate installation upon arrival, requiring no on-site modification or additional adjustments.
Product Advantages
Reduces belt mistracking and extends belt life
When the Head Pulley Tail Pulley are matched, the belt follows a consistent path from drive to tail, reducing edge wear and the need for tracking adjustments. This extends belt service life and lowers replacement costs.
Shortens installation time and minimizes downtime
Supplying them as a matched set means both pulleys arrive together with pre-aligned dimensions. There is no need to wait for one to be installed before measuring the other, significantly reducing downtime.
Targeted lagging options prevent unnecessary costs
We apply the right lagging for the job-using ceramic instead of rubber for the head pulley where appropriate, or wing-style instead of plain-face for the tail pulley. Selecting lagging based on operating conditions ensures effective anti-slip and self-cleaning performance while avoiding over-specification.
Customization Services
Head Pulley Customization
Based on your specifications for maximum tension, drive power, and torque, we calculate the shell wall thickness, shaft diameter, and bearing configuration. Diameter, shell length, and shaft-end dimensions are manufactured to match your existing drive station interface. Lagging options include herringbone rubber, diamond-pattern rubber, ceramic, or plain steel, with thicknesses ranging from 10mm to 20mm.
01
Tail Pulley Customization
Structural design is selected based on material characteristics-wing-style or spiral pulleys for materials prone to buildup, rubber-disc pulleys for sticky materials, and plain steel pulleys for clean operating conditions. The diameter and shaft-end dimensions are matched to the head pulley. Lagging options include rubber or smooth surfaces.
02
Bearings and Seals
Bearing brands include SKF, FAG, NSK, or high-quality domestic brands. Bearing housings are available in solid or split designs. Seals are selected based on dust and humidity levels in the operating environment.
03
Surface Treatment
Options include painting, hot-dip galvanizing, or heavy-duty anti-corrosion coatings, determined by the specific environment (e.g., mining, ports, or chemical plants).
04
Customization from Drawings/Samples
Customers provide drawings or samples; we verify the bearing center-to-center distance, shaft diameter, and keyway dimensions to ensure a matched set that allows for direct on-site installation. If no drawings are available, customers can provide installation dimensions, and we will generate drawings for confirmation.

Frequently Asked Questions (FAQ)
Q: Why should the head pulley and tail pulley be purchased together?
A: Purchasing them separately can lead to issues such as mismatched bearing center distances or inconsistent shaft diameter tolerances, requiring extra adjustments during installation or even causing belt misalignment. A matched supply ensures dimensional consistency and allows for direct installation.
Q: Can you manufacture head and tail pulleys based on my existing conveyor dimensions?
A: Yes. Simply provide the bearing center distance, mounting hole locations, shaft-end dimensions, and keyway specifications; we will manufacture the components according to these details to ensure a direct on-site replacement.
Q: How is export packaging handled?
A: Head Pulley Tail Pulley are packaged individually or as a complete set in wooden crates. Bearing seats and lagged surfaces are protected against rust and impact damage. Custom labeling and shipping marks are available upon request.
