THK BNF3610S-5RRG0-562.5L-C5 Ball Screw Assembly

The THK BNF3610S-5RRG0-562.5L-C5 Ball Screw Assembly is a precision-ground rotary-to-linear motion solution that uses a 36 mm screw shaft diameter and 10 mm lead to deliver high-accuracy positioning in demanding equipment. With a C5 accuracy grade, an overall shaft length of 562.5 mm, and hardened alloy steel construction, it offers high rigidity, low friction, and smooth, long-lasting motion for CNC machining centers, machine tools, semiconductor equipment, precision automation systems, and industrial positioning machinery. The assembly features a single flanged nut with a 75 mm outside diameter, a 120 mm flange diameter, and an overall nut length of 111 mm; the base model provides a ball center diameter of 37.75 mm, a thread minor diameter of 30.5 mm, and dynamic and static load ratings of 50.1 kN and 126.4 kN respectively, along with 680 N/μm axial rigidity. Lubrication is grease or oil compatible. The suffixes "S" and "5RRG0" are THK factory configuration codes, and THK does not publicly document their exact meanings; they should be interpreted only with the original engineering drawing or order specification. Maintenance teams and system integrators rely on this BNF-series ball screw for equipment repair, retrofit, expansion, and replacement.
