Description

Misumi – LHFSWF16 – Flanged Linear Ball Bearing

The Misumi LHFSWF16 is a high-precision flanged linear ball bearing specifically designed to provide smooth, low-friction linear motion along a shaft. Engineered for performance and reliability, this component is ideal for a wide range of automation systems, CNC machinery, 3D printers, and industrial equipment requiring precise linear guidance. Manufactured by Misumi, a trusted name in mechanical components, the LHFSWF16 is known for its consistency, quality, and customizable options to meet unique design specifications.

This particular model, the LHFSWF16, is designed to work with 16mm diameter shafts, which are commonly used in medium-load linear motion systems. The bearing features an integrated flange that simplifies mounting and alignment during installation. The flange style used in this model is the round face flange with tapped holes, which allows the unit to be securely bolted to a flat surface without the need for housing blocks or additional support hardware.

Construction and Materials

The Misumi LHFSWF16 is constructed using high-quality bearing steel with a finely machined inner and outer race, designed to accommodate a set of precision-ground steel balls. These balls recirculate within the raceway, allowing for smooth and accurate linear travel with minimal friction. The outer surface is precision-machined and treated to resist corrosion and wear over time.

The flanged face is an integral part of the outer bearing housing, providing stable and secure mounting while eliminating alignment issues. Tapped holes on the face of the flange allow for easy installation on panels, plates, or machine frames. This integrated design reduces assembly time and space, making it ideal for compact or modular equipment.

Performance and Application

The LHFSWF16 is specifically engineered to support radial loads while maintaining a low coefficient of friction during linear motion. This makes it suitable for applications where:

• Smooth motion is essential (e.g., CNC machines)

• Accurate shaft guidance is needed (e.g., pick-and-place automation)

• Space-saving installation is a requirement

Because of its flanged design and compact footprint, it’s commonly used in:

• CNC routers and mills

• Linear actuators

• Lab automation equipment

• 3D printing systems

• Factory automation setups

The internal ball circuit provides recirculating motion, which means the steel balls continuously move along the grooves, maintaining contact with the shaft to ensure stability and alignment throughout the stroke.

Installation and Maintenance

Installation is simple due to the flanged face — you only need to align the flange and tighten the mounting screws into the tapped holes. The bearing can be used in conjunction with shaft supports, end blocks, and linear guides to create a complete linear motion system.

This bearing typically requires very little maintenance, especially when operated in a clean or semi-clean environment. However, lubrication is recommended for optimum performance. It is compatible with standard grease or oil-based lubricants used in linear motion systems.
