THK HSR30A1SS Linear Guide Block Flange Type A

THK HSR30A1SS Linear Guide Block is a standard flange-type (A) carriage for THK HSR30 profile linear guide rails, delivering high-load, precise, low-friction motion in recirculating-ball courses. The four-row, four-way equal-load design provides consistent rigidity and smooth travel in all mounting orientations. Key dimensions: block width 90 mm, height 42 mm, length 98 mm; rail compatibility 30 mm with 28 mm rail width; mounting hole spacing 72 × 52 mm; mounting thread M10; rail mounting hole pitch 80 mm. Dynamic load rating is 40.5 kN and static load rating 53.7 kN. Weight is approximately 1.1 kg. Material is hardened bearing steel, and features include precision-ground raceways, four-way equal-load capability, an interchangeable design, and long service life. This block is designed for use with THK HSR30 rails and is widely used in CNC milling machines, machining centers, gantry systems, pick-and-place robots, semiconductor equipment, automated assembly lines, precision inspection machines, medical equipment, and material handling systems. Maintenance teams, machine builders, and system integrators commonly select the HSR30A1SS for equipment repair, retrofit, expansion, and replacement.
