THK Co., Ltd. SHW27CA1ZZC1140L Linear Block Bearing

Description:

The THK SHW27CA1ZZC1140L Linear Block Bearing Assembly is a complete caged ball linear motion guide consisting of one SHW27CA flange-type bearing block mounted on a 1,140 mm SHW27 wide guide rail. It is designed to provide high rigidity, excellent moment load capacity, and precise linear motion for demanding industrial automation and machine tool applications. Commonly installed in CNC machining centers, semiconductor manufacturing equipment, robotic systems, precision inspection machines, packaging equipment, and automated production lines. Maintenance teams and system integrators use this assembly for OEM replacement, machine repair, retrofit projects, and new precision motion systems.

Applications:

The THK SHW27CA1ZZC1140L is engineered for precision linear motion systems where high load capacity, low-profile construction, and superior moment rigidity are required. Its wide-rail configuration provides stable single-rail operation with smooth, low-noise travel, making it suitable for factory automation, electronics manufacturing, material handling systems, medical equipment, vision inspection systems, and high-precision assembly machinery.
