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.
