Product Description

Flanged straight linear bearings are core linear motion components designed for high-precision, smooth movement in a wide range of industrial and precision equipment. Characterized by a cylindrical main body that enables seamless sliding along a linear shaft and an integrated protruding flange, these bearings facilitate quick, secure mounting to housings or machine frames via bolts—eliminating the need for additional mounting brackets and simplifying assembly processes.

As trusted linear motion solutions, they are widely utilized across various industries proving indispensable in both precision-focused and high-volume industrial sliding applications:

Electronic equipment & Tensile testing machines
Digital 3D coordinate measuring equipment
Multi-axis machine tools & Punching machines
Tool grinding & Automatic gas cutting machines
Printers, Card sorting, and Food packaging machines

Primary Types of Flanged Linear Bearings

To meet diverse application requirements, flanged straight linear bearings are available in two primary types, each engineered with unique mechanisms to excel in specific operating conditions.

Flanged Linear Ball Bearings

These bearings leverage recirculating steel balls to minimize friction, enabling high-speed linear motion with exceptional accuracy. Constructed with heat-treated alloy steel shells, these bearings boast superior hardness and wear resistance, while polymer or resin retainers ensure quiet operation even at peak speeds. Equipped with double-seal designs, they effectively prevent dust, debris, and lubricant leakage, extending service life in standard industrial environments.

Versatile Configurations

They offer single or double length options, along with round, square, and oval/rectangular flange shapes—including end-mounted and center-mounted designs—to accommodate various installation layouts. Ideal for applications requiring rapid, precise movement, such as CNC machine tools, automatic printers, and digital measuring equipment.

Quality Control and Technical Excellence

All flanged straight linear bearings undergo rigorous quality control processes, from material selection to final assembly, to meet international industry standards. Whether for precision electronic equipment requiring micron-level accuracy or heavy industrial machinery demanding robust durability, these bearings provide reliable linear motion solutions tailored to specific needs.

Backed by technical expertise and comprehensive after-sales support, customers are assisted in selecting the optimal flanged linear bearing type, size, and configuration to maximize equipment performance and efficiency.

Frequently Asked Questions (FAQ)

What are the main advantages of flanged straight linear bearings? The integrated flange allows for quick and secure mounting directly to machine frames without extra brackets, simplifying assembly and ensuring high-precision alignment.

What types of flange shapes can I choose from? Bearings are available in round, square, and oval/rectangular flange shapes, with options for both end-mounted and center-mounted configurations to suit different installation spaces.

How do these bearings handle high-speed operation? Flanged linear ball bearings use recirculating steel balls and polymer retainers to minimize friction and noise, making them ideal for high-speed, accurate linear motion.

Are these bearings protected against dust and debris? Yes, they are equipped with a double-seal design that effectively prevents dust entry and lubricant leakage, extending the service life in industrial environments.

In which industries are flanged linear bearings commonly used? They are widely used in CNC machine tools, electronic equipment, 3D measuring tools, food packaging machinery, and industrial printers.

What materials are used in the construction of these bearings? The shells are typically made from heat-treated alloy steel for maximum hardness and wear resistance, combined with high-quality polymer or resin for internal retainers.
