Product Description for the African-Series Motorcycle Sprockets
Release Date:
2026-03-06
Motorcycle sprockets designed for the African market are manufactured from high-strength alloy steel and undergo rigorous heat treatment and precision machining. Their surfaces are treated with multiple protective coatings to withstand high-temperature, high-humidity, and corrosive environments. Customization is available for tooth count, hole positions, pitch, and accuracy grade, making these sprockets suitable for agricultural machinery, urban road vehicles, and light-duty transport vehicles. We also provide comprehensive services, including packaging, delivery schedules, quality assurance, and technical support.
Product Overview
This series of sprockets is optimally designed to meet the diverse road conditions and climatic challenges in Africa, balancing cost-effectiveness with durability, and is suitable for light- to medium-duty motorcycles as well as modified vehicles. Custom production is available based on customer drawings or samples, accommodating various tooth counts and hole-pattern requirements.
Main Parameters
1. Tooth count range: 10 to 200 teeth available; custom specifications available upon drawing.
II. Pitch and Hole Configuration: Supports multiple pitch specifications as well as keyway, spline, or multi-hole layouts.
3. Dimensional Accuracy: Standard accuracy grades are suitable for everyday applications; higher accuracy can be achieved by upgrading the machining grade.
IV. Materials and Strength: Different wall thicknesses and stiffening rib designs are provided for each model to enhance load-bearing capacity.
Materials and Heat Treatment Processes
Commonly used materials include alloy structural steels or carburizing steels; when necessary, chromium- and molybdenum-containing alloys are employed to enhance strength and fatigue resistance. Heat treatment processes encompass carburizing and quenching, as well as through-hardening or tempering, to ensure a balance between gear tooth surface hardness and core toughness, thereby preventing brittle fracture and extending service life.
Surface Treatment and Protection
A variety of surface treatments are available to suit different service environments, including zinc plating, electrophoretic coating, phosphating, black oxide, and corrosion-resistant coatings. In coastal or high-humidity environments, it is recommended to use a thick-film anti-rust coating or an electrophoretic coating followed by baked paint, with additional application of rust-preventive oil for protection during transportation and storage.
Applicable Scenarios and Performance Advantages
I. Agricultural and Rural Roads: Sand-and-dust resistance and impact durability, suitable for harvesters, tractor attachments, and conveying equipment.
II. Urban and Township Roads: Balancing wear resistance with low-vibration characteristics to enhance power transmission efficiency and ride comfort.
III. Light-duty Transportation and Modification: High-load-bearing structural design that supports modified power output and payload requirements.
IV. Advantages: high wear resistance, fatigue resistance, customizable, and easy maintenance.
Installation and Maintenance Recommendations
1. During installation, ensure that the wheel orientation and tooth clearance are adjusted in accordance with the technical manual, and that the chain tension is properly set.
2. Regularly inspect the gear tooth surfaces for wear and the condition of the anti-rust coating, and replace or repair any components found to be abnormal without delay.
3. In dusty or sandy environments, it is recommended to install additional protective covers and shorten the maintenance intervals.
Packaging and Shipping
Factory shipments are packaged with rust-preventive inner packaging and secured in wooden crates or on pallets to meet the requirements of sea, air, and land transportation. Packing lists, material certificates, and heat-treatment reports can be provided upon customer request.
Ordering and Delivery Time
When placing an order, please provide the model number, number of teeth, pitch, drawing or sample of the hole pattern, material and surface treatment requirements, and quantity. Sample delivery and small-batch orders are typically processed quickly; lead times for large batches depend on process complexity and order quantity.
