Description

Linear Rail SBR20 – 1 Meter Length

Specification

Linear Rail SBR Series: Available in 10 / 12 / 16 / 20 / 25 / 30 / 35 / 40 / 50 mm diameters.

Features

• Linear bearings offer a low-cost solution for linear motion systems, providing unlimited travel in conjunction with the cylinder axis. Due to point contact between the ball and the straight shaft, the load capacity is reduced.
• The balls rotate with minimal friction, enabling high precision and smooth motion.
• Flange linear bearings are categorized into: round flange, oval flange, guided wheel flange, guided oval flange, and extended round flange types.
• This unit comprises an aluminum housing, shafts, and an aluminum rail to prevent deflection.
• It is a complete sliding unit system that can be securely fastened with bolts to achieve high accuracy.
• The support rail unit ensures maximum rigidity and stiffness of the shaft throughout its entire stroke, guaranteeing optimal performance.

Comparison of HGH and SBR Linear Slide Blocks:

HGH Linear Guideway Blocks:

• Construction: Characterized by a rail with recirculating ball bearings, ensuring smooth operation and durability.
• Precision: Offers high precision, making it suitable for applications demanding accuracy, such as CNC machines and metrology equipment.
• Load Capacity: Capable of handling high loads and resistant to impact forces.
• Applications: Employed in heavy-duty industrial applications, including machine manufacturing, mechanical component production, and electronic assembly.

SBR Support Rail Guide Blocks:

• Construction: Features a cylindrical rail design with bearings that travel along the track, providing operational flexibility.
• Precision: Provides adequate precision; not recommended for applications requiring extremely high levels of accuracy.
• Load Capacity: Offers lower load capacity compared to HGH but exhibits greater flexibility.
• Applications: Suitable for general-purpose applications where high precision is not critical, such as 3D printers, small laser cutters, and general motion systems.

Summary of Differences:

• HGH: Ideal for applications demanding high precision and substantial load-bearing capabilities.
• SBR: Best suited for applications prioritizing flexibility and general use.

The selection between HGH and SBR should be based on the specific application requirements and desired performance characteristics.
