Single Screw Compressor: Components and Bearings
When you need a reliable, efficient way to compress air, single-phase screw compressors offer an innovative solution. These rotary-type positive-displacement mechanisms accommodate lower pressures and high volumes. With only three moving parts, these compressors can provide impressive longevity while keeping operational costs low.
WD Bearings provides your solution when you want to optimize your application. Our bearings are made with the highest-quality materials and manufacturing processes for consistency and next-level durability.
What Is a Single Screw Compressor?
A single-phase rotary screw compressor consists of a screw rotor and two symmetrical, star-shaped wheels. When the screw rotator rotates counterclockwise around its axis, it drives the two-wheel rotation. The two-wheel configuration rotates with one wheel in a clockwise motion and the other wheel in a counterclockwise motion. The volume gradually decreases throughout this process, causing air or gas compression.
This machinery is common in applications requiring a constant and consistent supply of compressed air. The ability to handle a high volume is ideal for industrial settings, manufacturing processes, and construction projects.
The Physical Influence of Bearings in Single Screw Compressors
The right bearings will operate smoothly for the application at hand. In the rotator, each screw channel works twice on both sides during a rotation to create a higher volume efficiency than other compressors. The symmetric wheels offset opposite radial forces, creating a balanced state. The gas force has no effect on the friction force.
Overall Bearing Life
At WD Bearings, we’re proud to use 99.98% VIM-VAR steel for our bearings. Our high-quality, durable materials offer a way to improve your operational performance.
Product Consistency
Our company is dedicated to producing quality results. We follow consistent manufacturing and quality control management practices.
Fracture Resistance
We provide bearings outfitted with robust components, like retainers and large rivets. Our durable designs resist damage from the vibrations of the screw rotators and star-shaped wheels.
The Social Influence of Single Screw Compressor Bearings
It’s important to choose the right components for your equipment so you can provide the highest performance possible. Your application’s performance plays a role in customer relationships and how your audience perceives your brand.
Common Bearings
Our professionals can help you choose the right bearings for your application. Some of the options we offer include:
- Four-point contact ball bearings: A four-point contact ball bearing supports axial loads in both directions and requires less space than double-row designs.
- Cylindrical roller bearings: A cylindrical roller bearing accommodates radial and axial loads with a greater load capacity and high-speed operations.
- Angular contact bearings: An angular contact bearing carries both radial and axial loads efficiently with nonstop contact.
- Deep groove ball bearings: The deep groove ball bearing handles radial and limited axial loads with a long lifespan.
- Tapered roller bearings: A tapered roller bearing transfers combined axial and radial loads evenly with reduced friction.
