SBR20UU Bearing Blocks Coavoo 2Pcs 20mm Plastic Slider for Linear Rail

Description

Product Overview

The SBR20UU bearing blocks from Coavoo are engineered to meet the demanding requirements of modern linear motion systems. Constructed from high‑grade engineering plastic, each block offers a 20mm open sliding interface that fits seamlessly into standard linear rail assemblies. The design incorporates a pressure plate that enhances stability while reducing wear, delivering a smooth, silent glide even under continuous operation. With a compact footprint—measuring just 3.27 x 2.17 x 2.13 inches—and a lightweight profile of 10.23 ounces, these blocks are easy to integrate into a wide range of CNC machines, 3‑D printers, robotic arms, and other precision equipment. Their waterproof, rust‑proof, and dust‑proof construction ensures reliable performance in harsh industrial environments, while the aluminum alloy components add extra rigidity where needed. The package includes two identical blocks, providing a complete solution for dual‑rail configurations.

Usage

Designed for versatility, the SBR20UU bearing blocks excel in applications that demand high precision and low maintenance. They are ideal for CNC milling machines where accurate positioning and repeatability are critical, as well as for 3‑D printing platforms that require steady, vibration‑free motion. The blocks also perform well in automated assembly lines, pick‑and‑place robots, and laboratory equipment where dust and moisture can compromise performance. Because the sliders are fully sealed, users can operate them in environments with coolant splashes, oil mist, or particulate exposure without fearing corrosion or degradation. Installation is straightforward: the blocks snap into the rail groove, and the pressure plate secures them in place, eliminating the need for additional fasteners or complex alignment procedures. This simplicity reduces setup time and allows technicians to focus on system calibration rather than mechanical adjustments.

Why Choose Us

Coavoo stands behind every bearing block with a commitment to quality and durability. Our manufacturing process follows strict ISO‑9001 standards, ensuring each component meets exact dimensional tolerances and surface finish specifications. The engineering plastic used in the SBR20UU series is selected for its high load‑bearing capacity, resistance to chemical exposure, and low coefficient of friction, which translates into longer service intervals and reduced downtime. Additionally, the integrated pressure plate design distributes forces evenly across the rail, minimizing stress concentrations and extending the lifespan of both the block and the rail. We provide responsive technical support and a clear warranty policy, giving customers confidence that their investment is protected. When you choose Coavoo, you benefit from a product that combines innovative design, rigorous testing, and a customer‑centric approach.

FAQ

What linear rail sizes are compatible with the SBR20UU blocks?

The blocks are designed for standard 20mm linear bearing rails, which are common in most CNC and automation setups. They fit both metric and imperial rail profiles that match the 20mm width specification.

Can the blocks be used in environments with coolant or oil exposure?

Yes. The engineering plastic material is fully sealed and resistant to water, coolant, and oil, making the blocks suitable for machining centers and other wet‑process applications.

How do I install the pressure plate on the block?

Installation is tool‑free. Align the pressure plate with the designated slots on the block, press it firmly until it clicks into place, and then slide the assembly into the rail groove. The plate locks the block securely without additional hardware.

What is the load capacity of each bearing block?

Each SBR20UU block can support a dynamic load of up to 150 kg and a static load of up to 300 kg, providing ample capacity for most medium‑size CNC machines and robotic applications.
