Overview
The Misumi LHFRM40 is a flanged linear ball bearing engineered to support and guide loads along a specified linear path. This single-bushing design delivers smooth, accurate linear motion for applications where precision and reliability are critical. The bushing features steel ball elements with hardened steel or stainless steel construction, making it suitable for various industrial automation and machinery applications.
Key Features
- RoHS10 compliant; medium-precision linear bushing with relaxed tolerances on outer diameter and length dimensions
- Multiple flange options: round flange, square flange, and compact flange configurations
- Shaft diameter support range from 6 mm to 40 mm (dr dimensions)
- Sealed design with optional lubrication; lithium soap-based grease recommended for optimal performance
- Anti-rust oil pre-applied at delivery to protect against corrosion
- Designed for low moment-load applications; double or multiple bushings recommended for offset loads
