A Type Pulley (SPA Type)
Product Identification:
A Type Pulley - SPA Type | Keywords: A-type Groove Adaptation, Light Load and High Speed, Universal Adaptation
Core Value: Specifically designed for A-type V-belts, the A type pulley has precise groove type and standard size, adapting to light-load and high-speed transmission scenarios. It has good transmission stability and versatility, and is a widely used light-load transmission component in industrial production.
Core Advantages:
The groove type of the A type pulley complies with the A-type V-belt standard, with high dimensional accuracy, precise fit with A-type V-belts, and a transmission efficiency of ≥95%.
The main body is made of gray cast iron HT200 or aluminum alloy, with light weight and small inertia, suitable for high-speed transmission (high allowable speed).
The hub is strengthened, with firm connection, suitable for medium-light load torque transmission, and stable operation without jitter.
The surface is subjected to rust prevention treatment, with simple structure, economical cost and strong versatility.
Material and Process:
The main body is gray cast iron HT200, subjected to precision casting + CNC machining process, the groove type is subjected to precision turning, the surface is subjected to blackening or painting rust prevention treatment, and the hub hole is equipped with a keyway (standard specification).
Application Scenarios:
Suitable for light-load and high-speed transmission systems such as small motors, fans, pumps, machine tool accessories, light industry machinery, covering general machinery, light industry, electronics, civil equipment and other industries, adapting to the transmission needs of various A-type V-belts using A type pulleys.
Installation and Maintenance:
Key connection installation, fixed by bolts or set screws after sleeving the shaft, with simple installation; daily maintenance needs regular inspection of groove wear and belt tension, avoiding belt slipping, with a long maintenance cycle.
Quality Assurance:
ISO9001 quality management system certification, 1-year warranty. It supports customization of specifications according to shaft diameter, number of grooves and reference diameter, regular models are available in stock, and provides A-type pulley selection parameter tables.
