A Medium Duty Polymer Sprocket Tapered Sleeve Conveyor Roller is an integrated component that combines a conveyor roller's function with a reliable drive mechanism. It's designed for medium-duty applications and uses a polymer (plastic) sprocket and a tapered sleeve to transfer motion from a drive chain directly to the roller, eliminating the need for separate bearings and sprocket assemblies.
In simple terms, it's a "ready-to-install" roller that you slide onto a shaft, lock in place with the tapered sleeve, and connect to a chain.
1. The Roller Tube
Material: Typically made from steel (painted, galvanized, or stainless) or sometimes polymer. For medium duty, it's often a galvanized steel tube with a wall thickness suitable for moderate loads.
Function: This is the cylindrical surface that physically carries the product. Its diameter and length define the roller's size (e.g., 50mm diameter x 500mm long).
2. The Polymer Sprocket
Material: Made from a high-performance engineering polymer like Nylon, Acetal (POM/Delrin), or Polyamide.
Function: This sprocket is permanently attached to one end of the roller tube (often press-fit, molded-on, or locked with a key). Its teeth are designed to engage with a standard roller chain (e.g., ANSI #35, #40, #50, etc.).
Why Polymer?
Reduced Noise: Much quieter than metal-on-metal contact.
Corrosion Resistance: Will not rust.
Lubrication-Free: Operates dry, reducing contamination risk in clean environments (e.g., food, packaging).
Cost-Effective: Generally cheaper to produce than a machined steel sprocket.
3. The Tapered Sleeve (or Taper-Lock Bushing)
Material: Usually precision-cast or machined steel.
Function: This is the brilliant part of the design. It's a bushing with a tapered inner bore and external threads. It fits inside the roller's end cap.
How it Works: When you tighten a hex nut on the external threads, the sleeve is pulled axially. Due to its taper, it is forced radially outward, creating an immense mechanical interference fit with the inside of the roller and simultaneously clamping down tightly onto the square or round drive shaft. This locks the roller securely to the shaft without any welding, set screws, or pins.
4. Bearings: Located inside the roller, allowing it to spin freely on the stationary drive shaft. They are typically pre-lubricated and sealed (e.g., deep-groove ball bearings).
Installation: The roller is slid onto the pre-installed square or round drive shaft of the conveyor frame.
Locking: The hex nut on the tapered sleeve is tightened with a wrench. This action expands the sleeve, locking the roller assembly firmly onto the shaft. This connection transmits torque from the shaft to the roller.
Driving: A chain, driven by a motor, is engaged with the polymer sprocket on the roller. As the chain moves, it turns the sprocket, which turns the entire roller (because the sprocket is fixed to the tube, and the tube is locked to the shaft via the sleeve).
Easy Installation & Removal: The tapered sleeve system allows for quick mounting and dismounting without specialized tools. Loosening the nut breaks the lock, allowing the roller to be slid off the shaft easily for maintenance or replacement.
Zero Maintenance: The sealed bearings and lubrication-free polymer sprocket mean no regular greasing or upkeep is required.
Excellent Alignment: The tight lock of the tapered sleeve ensures perfect roller-to-shaft alignment, preventing wobble and uneven wear.
Reduced Vibration: The polymer sprocket dampens vibration and noise compared to all-metal systems.
Cost-Effective: It's an all-in-one solution, reducing the number of parts to inventory and the labor time for assembly.
This type of roller is ideal for medium-duty powered roller conveyor systems such as:
Package Handling: In distribution centers and parcel services.
Food & Beverage Processing and Packaging: Where corrosion resistance and cleanability are important.
Boxed Goods Conveyors: For moving cartons in manufacturing and warehousing.
Assembly Line Conveyors: Where precise and reliable roller movement is needed.
Based on the R2224 series double polymer sprocket straight steel roller , the tapered sleeve sprocket driven roller is shockproof, abrasion resistant, and carbon steel roller clinder be covered in polypropylene (PP) tapered sleeves.
High performance polyamide sprockets are used as the roller's driving element instead of conventional steel ones, which results in comparatively less operating noise.
The bearing unit, which is made up of a precision ball bearing, polymer bearing housing, and end cover, is crucial. It's not just because it looks nice; it also runs quietly and smoothly.
The roller's end cap effectively withstands splashes of water and dust in a working setting.
To avoid causing the sprocket and chain to wear out too quickly, it is advised not to surpass a 5° angle between the tapered rollers (axis angle).
Typically, conveyed goods carry no more than 50 kg.
Working temperature range -5℃ to +40℃.

Application for Medium Load Curved Roller Convey
In essence, the Medium Duty Polymer Sprocket Tapered Sleeve Conveyor Roller is a smart, efficient, and user-friendly component. It combines the durability of a steel roller, the quiet, clean benefits of a polymer sprocket, and the supremely reliable and easy-to-use locking mechanism of a tapered sleeve, making it a very popular choice for modern conveyor design.
