China Custom Guaranteed Quality Finished Bore QD Sprocket Chain & Sprocket in Steel and Stainless Steel

Product Description

The Guaranteed Quality Finished Bore QD sprocket chain & sprocket in steel and stainless steel offers superior performance and longevity. The QD bushing is renowned for its ease of installation and removal, thanks to its tapered design which ensures precise clamping on the shaft. Additionally, it supports blind installation with its keyed post and hub.

Installation Guide

To properly install a QD sprocket, follow these meticulous steps:

  1. Ensure the tapered surface of the bushing and the interior of the driven product are clean and free of anti-seize lubricant.
  2. Insert the bushing into the sprocket or the designated part.
  3. Insert the cap screws loosely into the upper pull holes, keeping the bushing loose to allow for sliding fitment on the shaft.
  4. Using the keys on the shaft, slide the sprocket to the desired position, ensuring the cap screw heads remain accessible.
  5. Align the sprocket and alternately tighten the screws gradually until they are secure. Avoid using an extended wrench handle or allowing the sprocket to contact the bushing flange; there should be a gap between them.

Key Features

The QD sprocket is distinguished by its quick removal bushing design and flange that secures the bushing to the sprocket. It includes a four-degree taper and cap screws for seamless installation. The bushing’s hardened teeth are engineered to resist wear and withstand harsh conditions.

Size Variations

QD sprockets come in various sizes, catering to different applications. Single-strand steel sprockets are available with or without hardened teeth, and the sprocket diameter dictates the number of teeth it can accommodate.

Installation Precautions

Correct installation is crucial for the optimal performance of the QD sprocket. Follow these steps rigorously:

  • Inspect the sprocket hub for contaminants before installation.
  • Position the QD bushing correctly and use a torque wrench for even tightening.
  • Avoid overtightening to prevent premature bushing damage.
  • Ensure there is a clearance between the QD bushing flange and the chain hub to mitigate excessive stress.
  • Avoid using anti-seize lubricant on the tapered surfaces, as it can damage the sprocket and void warranties.

Quick Removal Bushing

The QD sprocket is designed with a tapered flange that links the bushing to the sprocket, secured by cap screws for easy removal and installation. The common sizes for QD sprockets include 40, 50, 60, and 120, with each sprocket incorporating features to facilitate maintenance.

Hardened Teeth

QD sprockets feature hardened teeth with a black oxide finish to prevent rust and improve efficiency. These teeth are precision machined for maximum durability, capable of withstanding adverse weather conditions. The innovative smart tooth technology includes a wear indicator pin that reveals when the teeth profile starts to reverse, ensuring timely maintenance.

Sprocket Quality Testing

Each manufacturing process is followed by rigorous inspections and testing to ensure the highest quality sprockets are delivered to the market.
