Product Overview
Our Greenhouse Pillow Block Bearings are engineered to provide long-lasting, stable shaft support for a wide range of greenhouse structures and systems. Manufactured from high-strength carbon steel and protected with a zinc galvanization finish, these bearings are ideal for humid, high-moisture environments where corrosion resistance is a top priority.
They are compatible with common pipe diameters used in greenhouse systems, including 32mm, 48mm, 60mm, and custom sizes based on your design requirements.
Key Product Features
1.Corrosion-Resistant Construction
Greenhouses are constantly exposed to moisture, fertilizers, and temperature variations. Our pillow block bearings are made from premium-grade carbon steel, and the surface is hot-dip or electro-galvanized, offering superior rust resistance compared to untreated units.
2.Smooth Operation
Each bearing unit is precision-machined to allow low-friction shaft rotation, ensuring that greenhouse mechanisms like ventilation systems operate smoothly with minimal energy loss.
3.Easy Installation
The integrated base with bolt holes makes mounting fast and easy. The unit is pre-assembled and pre-lubricated, reducing the need for complex installation steps or additional preparation.
4.Durable and Reusable
These bearings are built for extended service life in outdoor agricultural conditions. They can be reused or replaced without affecting the surrounding structure, making maintenance quick and cost-effective.
5.Customizable Dimensions
Available in 32mm, 48mm, and 60mm pipe compatibility by default, with the ability to custom-manufacture other sizes or surface finishes for OEM clients.

Applications in Greenhouse Structures
Our pillow block bearings are specially designed for greenhouse systems and are compatible with various automation and support mechanisms. These include:
1.Roof Ventilation Systems
Mounted at key pivot points along the ventilation shaft, the bearings ensure smooth rotation and precise control over air flow. They support the shaft against torque loads and prevent premature wear.
2.Curtain Side Systems
Whether roll-up or sliding, curtain systems rely on axial support. Our pillow block bearings enable efficient movement of the curtain tube, making it easier to regulate temperature and humidity inside the greenhouse.
3.Manual and Motorized Drive Units
Bearings are essential in connecting the drive motors or manual cranks to the shaft systems. A strong and reliable bearing prevents misalignment and system jamming.
4.General Structural Support
In larger greenhouses or commercial tunnels, pillow block bearings are also used in conveyor systems, irrigation arms, and shading screen mechanisms.
Installation and Maintenance Tips
Mount on a level surface: Ensure the base is flat and aligned with the axis of rotation.
Use anti-rust bolts and washers to match the corrosion resistance of the bearing unit.
Regularly check lubrication, especially in motor-driven systems. Re-lubricate through the built-in port every 6–12 months depending on usage.
Replace if noisy or misaligned: Bearings should operate quietly; abnormal noise may indicate wear.
