THK 2RSR770L Linear Slide Rail With Ball Bearing Carriage

The THK 2RSR770L Linear Slide Rail with Ball Bearing Carriage is a miniature precision LM Guide assembly featuring a 70 mm rail and a compact carriage measuring approximately 22 × 17 × 8 mm, designed for smooth, low-friction, high-rigidity linear motion in equipment with limited installation space. Part of THK's RSR Miniature LM Guide Series, it employs a four-way equal-load recirculating ball design to deliver precise travel and stable positioning, using stainless steel for the rail, block, and balls and a top-mount installation style. With lubrication compatible with grease or oil and stainless steel construction for corrosion resistance, this guide is commonly used in electronics manufacturing equipment, pick-and-place systems, miniature robotics, precision inspection equipment, and laboratory automation; machine builders, maintenance technicians, and system integrators rely on it for new equipment builds, precision retrofits, repairs, and replacements of miniature motion systems. Common replacements include THK 2RSR760L, 2RSR780L, and 2RSR7100L.
