Description

Linear Rail SBR20

4 Meter Length

Specification

Linear Rail SBR Series Available Models: SBR10, SBR12, SBR16, SBR20, SBR25, SBR30, SBR35, SBR40, SBR50 (mm)

Features

• The linear bearing system offers a cost-effective solution for linear motion applications with unlimited travel along a cylinder axis. Due to the point contact between the ball and the straight shaft, the load capacity is moderate.
• The ball rotation operates with minimal friction, enabling high-precision and smooth motion.
• Flange linear bearings are available in various types: round flange, oval flange, guided wheel flange, guided oval flange, and extended round flange.
• This product is a sliding unit comprising an aluminum housing, shafts, and an aluminum rail to prevent deflection.
• It constitutes a complete sliding unit system that can be securely fastened with bolts, ensuring high accuracy.
• The support rail unit provides maximum rigidity and stiffness to the shaft across the entire stroke, guaranteeing optimal performance.

HGH Block vs. SBR Block Comparison

HGH Block (Linear Guideway)

• Structure: HGH linear guideways feature a rail with recirculating ball bearings, offering smoothness and durability.
• Precision: High precision, suitable for applications requiring fine accuracy, such as CNC machinery and metrology equipment.
• Load Capacity: High load-bearing capacity and resistance to impact.
• Applications: Used in heavy-duty industrial applications, including machine manufacturing, precision component production, and electronic assembly.

SBR Block (Support Rail Guide)

• Structure: SBR linear guides utilize a supported round shaft with recirculating ball bearings, providing operational flexibility.
• Precision: Moderate precision, not ideal for applications demanding extremely high accuracy.
• Load Capacity: Lower load capacity compared to HGH, but offers greater flexibility.
• Applications: Suitable for less precision-critical applications such as 3D printers, small laser cutters, and general motion systems.

Summary of Differences

• HGH: Recommended for applications demanding high precision and significant load capacity.
• SBR: Recommended for applications prioritizing flexibility and general-purpose use.

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