Description
Linear Bush LM 20UUAJ Linear Motion Bearing
The Linear Bush LM 20UUAJ is a high-quality, adjustable metric linear ball bushing bearing designed for exceptionally smooth and precise linear motion. Engineered for durability and reliable performance, this bearing is an indispensable component for a wide array of industrial and automation applications.
The “UUAJ” designation signifies its key features: “UU” indicates that it is sealed on both sides with high-quality rubber seals, providing excellent protection against dust, dirt, and other contaminants, thereby extending its lifespan. The “AJ” denotes its adjustable type, allowing for precise clearance adjustments between the bearing and its shaft using washers. This adjustability ensures optimal performance and fit within your machinery.
Constructed from robust Chrome Steel SAE-52100 (with a hardened Gcr15 steel housing and heat-treated, hard chrome-plated Chromium steel balls), the LM20 UUAJ delivers high rigidity and a low coefficient of friction. Its internal resin retainer minimizes running noise, contributing to a quieter operational environment. Pre-lubricated with light oil, it is ready for immediate installation and use, making it an efficient choice for your linear motion needs.
