HSR25R1UU(GK) Block
The THK HSR25R1UU(GK) Block is part of the HSR series of linear-motion guide blocks, designed for smooth, precise, and high-rigidity movement on a matching 25 mm rail. It features a full-complement ball bearing construction that provides nearly equal load capacity in all directions, including radial, reverse radial, and lateral. The block has a carriage width of 48 mm, a height of 40 mm, and a block length of 83.1 mm.
The HSR25R1UU includes M6 tapped mounting holes and end seals (“UU” type) to protect the ball-bearing interior from dust and contaminants. Its design offers a basic dynamic load rating of approximately 27.6 kN and a basic static load rating of around 36.4 kN, ensuring robust performance under heavy loads.
Because of its balanced multi-direction load handling, sturdy construction, and precise low-friction motion, the HSR25R1UU(GK) block is ideal for CNC machines, industrial automation, and other precision machinery requiring reliable, smooth linear motion.
HSR15A1UU(GK) Block
The THK HSR15A1UU (GK) is a compact, high-precision linear guide designed for smooth, stable, and low-friction linear motion. It features a 15 mm-wide rail and a compact block measuring 47 mm in width, 24 mm in height, and 56.6 mm in length, making it ideal for applications where space is limited.
Inside the block, multiple recirculating ball bearings run along precision-ground raceways, providing smooth, accurate, and repeatable motion. Its four-way contact design distributes loads evenly in radial, reverse-radial, and lateral directions, ensuring rigidity and stability even under varied load conditions.
The HSR15A1UU (GK) is perfect for light to medium-duty tasks in small CNC machines, precision jigs, automation assemblies, measurement or inspection equipment, and other machinery requiring compact, precise linear motion. Despite its small size, it offers a high dynamic load capacity (~10.9 kN) and static load capacity (~15.7 kN), making it a reliable and versatile solution for precision applications.
