Thk SRS9XGMUU+115LM Miniature Linear Guide Assembly

Product Description

The THK SRS9XGMUU+115LM is a miniature linear guide assembly combining a compact recirculating ball block with a matched guide rail in a single ready-to-install unit. The block measures 30.8mm in length, 20mm in width, and 8.5mm in height. The rail is 115mm long, 9mm wide, and 5.5mm high, yielding a 10mm overall assembly height with zero overhang. Transverse hole spacing is 10mm and lateral hole spacing is 15mm. The block uses M3 x 2.8mm mounting holes and features a 2-row ball circuit drawn from the SRS7GM series. This assembly is used in precision positioning stages, automation equipment, and instrumentation where minimal cross-section and smooth low-friction travel are required. Licensed mechanical technicians and automation integrators are the primary installers.

This unit is suited for compact linear motion applications in both light-duty industrial automation and precision instrument design. The miniature form factor makes it appropriate for pick-and-place systems, scanning stages, medical device sub-assemblies, and other space-constrained mechanisms. The preassembled block-and-rail format reduces alignment time during initial build or field replacement. No compatibility with specific third-party systems is stated by the manufacturer for this assembly.

Key Features

• Preassembled miniature linear guide - block and 115mm rail matched at the factory
• 2-row recirculating ball circuit for smooth, low-friction linear travel
• Block dimensions: 30.8mm long x 20mm wide x 8.5mm high
• Rail dimensions: 115mm long x 9mm wide x 5.5mm high
• 10mm transverse hole spacing and 15mm lateral hole spacing for straightforward mounting
• M3 x 2.8mm block mounting holes sized for standard metric fasteners

Compatibility

Designed as an OEM-style miniature linear guide assembly consistent with the THK SRS series block-and-rail format; confirm mounting hole pattern and rail width against your application drawings before installation.

Installation Notes

Installation is typically performed by mechanical technicians or automation integrators familiar with precision linear motion systems. The mounting surface should be clean, flat, and free of burrs before securing the rail to avoid introducing misalignment. Tighten block and rail fasteners to the torque values specified in the THK installation manual for the SRS series. Do not disassemble the block from the rail in the field, as recirculating ball elements may be displaced.
