Description
Product Overview
The 80/20 linear roller bearing is a precision T-slotted aluminum unibearing assembly engineered for the 25 series extrusions. It measures 52.4mm tall, 40.85mm wide, and 47mm long, riding smoothly on the 25mm side of the extrusion. The assembly includes pads, screws, and shims, with pads made from self-lubricating UHMW material to reduce friction and maintenance. This bearing is ideal for linear motion applications in industrial settings, offering durability and ease of integration into custom frameworks.

Usage
This linear roller bearing is suited for industrial and scientific environments, including automation systems, CNC machinery, and custom fabrication projects. It is designed for engineers, manufacturers, and DIY enthusiasts who require reliable linear motion components. The bearing assembly works effectively in applications where precise movement along T-slotted extrusions is needed, such as in conveyor systems, sliding doors, and robotic arms.

FAQ
What is the weight capacity of this linear roller bearing?
The bearing is designed for standard loads in linear motion systems; specific weight limits depend on the extrusion and application setup, but it handles typical industrial demands effectively.
Can I use this bearing with other series of extrusions?
No, this bearing is specifically made for 25 series T-slotted aluminum extrusions and may not fit or function properly with other sizes or types.
How do I maintain the UHMW pads?
The UHMW pads are self-lubricating, so no regular maintenance is required. Simply keep them clean from debris to ensure smooth operation over time.
What tools are needed for installation?
Basic tools like hex wrenches for the included screws are sufficient. The assembly is straightforward and does not require specialized equipment.
Is this bearing suitable for outdoor use?
While the aluminum and UHMW materials are resistant to corrosion and wear, prolonged exposure to harsh outdoor elements may affect longevity; it is best used in controlled environments.
