Frequently asked question (FAQ)

Question: What distinguishes the Linear Bushing LM Type from other linear motion bearings?
Answer: The Linear Bushing LM Type is designed with a high-precision steel outer sleeve and a single ball recirculation path. Unlike plain bushings, it uses rolling contact through hardened steel balls, resulting in low friction and high positioning accuracy. Its design ensures uniform load distribution and smooth linear motion, even under high-speed or repetitive stroke conditions.
Question: What materials and surface treatments are used in the Linear Bushing LM Type?
Answer: The outer sleeve is made from precision-ground steel with no additional surface treatment to maintain dimensional accuracy. The rolling elements (balls) are made of high-carbon bearing steel, providing high hardness and wear resistance. This construction ensures stability and longevity under continuous linear motion applications.
Question: How does the Linear Bushing LM Type accommodate load and movement?
Answer: The Linear Bushing LM Type supports loads through a contact area formed between the balls and the shaft, distributing stress uniformly along the contact lines. It is optimized for radial loads while allowing smooth linear reciprocating motion. However, it is not intended for rotational or moment loads unless specifically supported by a guide structure.
Question: What is the operational temperature range and lubrication requirement for the Linear Bushing LM Type?
Answer: The standard operating temperature is up to 80°C. Although it can be used without lubrication, applying lithium-based grease or oil is recommended for continuous operation to reduce wear and extend service life. The open type variants allow easier maintenance and lubrication access in high-duty applications.
Question: What are the available configurations of the Linear Bushing LM Type?
Answer: This series includes multiple styles such as Standard Type, Open Type, and Clearance Adjusting Type. The open type allows shaft clearance adjustment or preloading for increased rigidity. The clearance adjusting shape ensures optimal shaft fit for precision positioning and minimal vibration during motion.
Question: How is the Linear Bushing LM Type installed and aligned for optimal performance?
Answer: Proper shaft alignment and housing tolerance are critical. The shaft surface hardness should be above HRC 58, and roughness below Ra 0.2 μm. The housing bore tolerance should follow H7 specifications, ensuring correct interference fit without distortion. Misalignment may cause uneven ball contact and reduced lifespan.
Question: What accuracy grades are available, and how do they affect performance?
Answer: The Linear Bushing LM Type is available in High Grade and Precision Grade accuracy levels. Precision grade models feature tighter dimensional tolerances and reduced radial play, providing superior repeatability for applications such as semiconductor assembly, optical inspection, or fine machining systems.
