THK BNF3610S-5RRG0-562.5L-C5 BALL SCREW ASSEMBLY

Description:

The THK BNF3610S-5RRG0-562.5L-C5 Ball Screw Assembly is a precision ground ball screw featuring a 36 mm screw shaft diameter, 10 mm lead, C5 accuracy grade, and an overall screw shaft length of 562.5 mm. Designed to convert rotary motion into precise linear motion, it delivers low friction, high rigidity, and excellent positioning accuracy for demanding industrial applications. Commonly installed in CNC machining centers, machine tools, semiconductor equipment, precision automation systems, and industrial positioning machinery. Maintenance teams and system integrators use this ball screw for equipment repair, retrofit, expansion, and replacement.

Applications:

The THK BNF3610S-5RRG0-562.5L-C5 belongs to the THK BNF Series of precision ground ball screws. The base model BNF3610 features a 36 mm screw shaft diameter and a 10 mm lead, making it suitable for high-load, high-precision positioning applications. The "562.5L" designation identifies an overall screw shaft length of 562.5 mm, while the "C5" suffix specifies the accuracy grade. The remaining suffixes "S" and "5RRG0" are THK factory configuration codes related to shaft-end machining, preload, or customer-specific manufacturing options and are not publicly decoded by THK; therefore, their meanings should not be inferred without the original engineering drawing or order specification.
