Thk HSR15280LGKRAIL Linear Guide Rail 280mm 15mm

Product Description

The THK HSR15280LGKRAIL is a linear guide rail designed for use in precision linear motion systems. This HSR-series rail measures 280mm in overall length, 15mm in overall width, and 15mm in overall height. It features a 4-way load design, meaning it supports radial, reverse radial, and lateral load directions simultaneously. Mounting holes are spaced 60mm apart and sized at 4.5mm x 7.5mm with a 5.3mm counterbore depth, allowing secure fastening to machine bases, stages, and structural members. The rail pairs with THK HSR15 series carriages to form a complete linear guide assembly. Installation is typically performed by mechanical technicians and machine builders working in automation, manufacturing equipment, or precision positioning applications.

This rail is suited for light-duty to medium-duty linear motion applications in industrial automation, CNC machinery, semiconductor equipment, medical devices, and custom fabrication setups. The HSR15 profile is a compact size appropriate for applications where space is limited but smooth, low-friction linear travel is required. A single rail is included per unit, and it is intended to mate with a compatible HSR15 carriage block sold separately.

Key Features

• 280mm overall length provides a defined travel envelope for compact linear stages
• 15mm width and 15mm height profile fits tight-clearance machine frames
• 4-way load capacity handles radial, reverse radial, and lateral forces in a single rail
• 60mm hole-to-hole spacing simplifies bolt-pattern layout during machine assembly
• Mounting holes sized at 4.5mm x 7.5mm with 5.3mm depth for standard socket head cap screws
• Part of the THK HSR series, a widely adopted standard in industrial linear motion

Compatibility

Designed for use with THK HSR15 series carriage blocks as part of a complete linear motion guide system. Specific compatible carriage part numbers should be confirmed against THK HSR15 series documentation prior to ordering.

Installation Notes

Installation should be performed by a qualified mechanical technician or machine builder familiar with precision linear guide assembly. Clean and deburr the mounting surface before fastening the rail to ensure proper alignment and flatness. Torque fasteners per the machine design specification using appropriate socket head cap screws that match the mounting hole dimensions. Pair the rail with a properly matched HSR15 carriage block and verify smooth travel across the full rail length before placing the assembly into service.
