Product Advantages and Features
1. Compact Structure and Precise Adaptation: The INA Guide Rail KUVE 15 W L=70 adopts a narrow design ("W" stands for narrow rail series), with a width suitable for the installation space of small equipment. The standard length of 70mm (L=70) can directly meet the short-stroke transmission needs without additional cutting, greatly simplifying the equipment assembly process. It is especially suitable for transmission systems with limited space such as woodworking machinery and small CNC machine tools.
2. High Load Capacity and Stable Operation: As a ball-type linear guide rail, it has a built-in precision ball circulation structure, with a radial rated dynamic load of 4.2kN. It can stably bear combined loads in vertical and horizontal directions. During high-frequency reciprocating movements such as board pushing and component positioning in woodworking machinery, it can avoid jamming caused by uneven loads and ensure smooth transmission.
3. Wear Resistance, Durability and Low Maintenance: The guide rail body is made of high-hardness quenched steel (surface hardness ≥HRC58), combined with INA special grease, which has excellent wear resistance and a service life of more than 10,000 hours under normal working conditions. At the same time, the ball circulation system has good sealing performance, which can block the intrusion of wood chips and dust (suitable for dusty environments in woodworking workshops), reducing the frequency of daily cleaning and lubrication and lowering equipment maintenance costs.
4. High-Precision Guidance and Low Noise: Processed by precision grinding technology, the guide rail parallelism error is ≤0.02mm/m, which can achieve millimetre-level positioning accuracy, meeting high-precision needs such as board cutting positioning and engraving head movement in woodworking machinery. During operation, the friction coefficient between the balls and the rail contact surface is only 0.003-0.005, and the noise is controlled below 55 decibels, improving the workshop operating environment.
5. Wide Compatibility: It is compatible with the full range of INA slider of the same model (such as KUVE 15 B slider), and can flexibly match single-slider or multi-slider combinations according to load requirements. At the same time, it supports linkage with common transmission components (such as ball screws, timing belts), and can be easily integrated into the automated transmission system of woodworking machinery to improve the overall transmission efficiency of the equipment.

Product Application Scope
1. Engraving Head Transmission of Small Woodworking Engraving Machines: Suitable for short-stroke movement scenarios of engraving heads in small woodworking engraving machines, such as carving patterns on small solid wood parts (e.g., wooden combs, small decorative wooden plaques) and engraving textures on wood mouldings. The short length of 70mm can accurately match the movement stroke of the engraving head, and the narrow width of 15mm can save the internal installation space of the equipment; the positioning accuracy of ±0.01mm can ensure the neat edges of carved patterns and avoid texture misalignment caused by guide rail deviation, meeting the needs of fine carving.
2. Auxiliary Positioning Mechanism of Woodworking Panel Saws: Used in the auxiliary positioning link of board pushing in woodworking panel saws to support the pressure during board pushing. Its radial rated dynamic load reaches 4.2kN, which can stably bear the force when pushing man-made boards of different thicknesses (e.g., particleboard, MDF); the IP54 dust-proof and splash-proof grade and double-side rubber sealing rings can block the intrusion of wood chips and a small amount of cooling liquid generated during cutting, avoiding guide rail jamming, ensuring cutting accuracy, and adapting to the dusty working environment of woodworking workshops.
3. Sanding Belt Adjustment Component of Woodworking Sanders: Integrated into the sanding belt tension adjustment structure of woodworking sanders to realize fine control of sanding belt tension. The low friction coefficient (0.003-0.005) can make the sanding belt adjustment action smoother, facilitating operators to finely adjust the tension; the high-hardness quenched steel material (surface hardness ≥HRC58) can resist slight impacts and wear during sanding, reduce component loss, prolong the service life of the sanding belt adjustment mechanism, and ensure stable sanding operations.
4. Tenon Processing and Positioning Mechanism of Woodworking Mortise and Tenon Machines: Suitable for the positioning components of tenon processing in woodworking mortise and tenon machines to ensure the dimensional consistency of tenon processing. Matched with the INA KUVE 15 B standard slider, the 70mm length and compact structure can adapt to the narrow installation space of the positioning mechanism; the high precision with parallelism error ≤0.02mm/m can ensure the positioning accuracy during tenon processing, improve the fit of mortise and tenon connections, and help small and medium-sized woodworking mortise and tenon machines achieve automated transmission upgrades.
