Thomson Industries 511H25B0 Long Ball Carriage

Product Description

The THOMSON INDUSTRIES 511H25B0 is a standard long ball carriage designed for use in linear motion systems requiring smooth, low-friction travel along round rail shafts. Built from steel and rated for industrial-grade applications, this carriage measures 103.5 mm (4.07 inches) in length, 70 mm (2.76 inches) in width, and 30.5 mm (1.2 inches) in height, with an assembly height of 36 inches. The transverse hole spacing is 45 mm (1.77 inches) and the lateral hole spacing is 57 mm (2.24 inches), with an M8 bolt hole pattern and a 23.5 mm overhang. It is installed by mechanical and automation technicians working on precision linear motion assemblies.

This carriage is suited for use in automation equipment, machine tool platforms, material handling systems, and similar industrial applications requiring repeatable linear travel. The 500 Series designation identifies it within the Thomson Industries standard round rail product family. It is appropriate for both horizontal and vertical shaft orientations depending on system design. Installation is typically performed by mechanical engineers or maintenance technicians familiar with linear bearing systems and precision shaft alignment.

Compatibility

Designed for use with Thomson 500 Series round rail linear motion shafting systems. Verify shaft diameter and rail configuration against your assembly drawings before installation.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with linear bearing and shaft alignment procedures. Power down and de-energize any connected actuators or drives before servicing the carriage or associated rail components. Ensure the mounting surface is flat and clean before torquing fasteners into the M8 bolt pattern. Do not force the carriage onto the shaft; misalignment during assembly can damage the ball elements and reduce service life.
