Before variable frequency drives became common, machines relied on mechanical ingenuity to control speed and step pulleys remain a trusted solution even today. Designed with multiple pulley diameters on a single hub, step pulleys allow operators to change speed ratios quickly and reliably by shifting the belt position. As a precision-focused Step Pulley Manufacturer in India, JobWurx manufactures step pulleys that deliver accurate speed variation, stable belt tracking, and long-term durability for workshop and industrial machinery.
JobWurx step pulleys are engineered for applications where simple, dependable speed control is preferred over complex electronic systems.
A step pulley consists of two or more pulley steps, each with a different diameter, allowing multiple speed ratios from a single drive arrangement. JobWurx machines each step with consistent groove geometry to ensure smooth belt movement and uniform load distribution.
Key industry-relevant technical specifications include:
These specifications allow smooth speed changes without belt slip or excessive wear.
As a dependable Step Pulley Supplier in India, JobWurx supports OEMs, machine builders, and maintenance teams who require repeatable pulley geometry across production batches and replacement units.
Customers rely on JobWurx step pulleys for:
This reliability is especially important in machines that undergo regular speed adjustments.
Step pulleys are widely used where variable speed is required without the need for electrical control systems. JobWurx manufactures step pulleys suitable for both light-duty and medium-duty machinery.
Common applications include:
In these applications, mechanical speed control offers simplicity, safety, and low maintenance.
JobWurx also operates as a reliable Step Pulley Exporter from India, supplying pulleys to international machinery manufacturers and distributors. Export units undergo dimensional inspection, balance checks, and surface finish verification prior to dispatch.
Export advantages include:
JobWurx step pulleys are manufactured using:
Available configuration options include:
If the diameter difference between steps deviates by more than ±0.5 mm, speed ratios can shift by 3–6%, affecting machining accuracy and surface finish. JobWurx controls machining and inspection processes to ensure each step delivers predictable speed output and consistent torque transmission.
Jobwurx Industrial Ventures supplies and supports a wide range of industrial brands along with its own manufacturing capabilities, ensuring reliable and compatible solutions across applications.
