Описание: Ball screw | KK module assembly | Guide screw | Linear guide | Profile module
KK module and embedded screw module are two common types of linear motion modules, which have significant differences in structural design and performance characteristics.
1、 Structural design differences
KK module: adopting an integrated design, the nut seat of the ball screw is directly integrated with the slider of the U-shaped linear slide, forming a "three in one" structure (screw, guide rail, slider integrated), without the need for additional installation of independent guide rails and multiple sliders.
Embedded screw module: The track is embedded inside the aluminum body, and the external design includes fixed installation holes and centralized oil injection nozzles, which can be maintained without disassembling the upper cover. The dust-proof structure of its steel strip is specifically optimized for dust-free environments, reducing the risk of dust generation.
2、 Performance Characteristics Comparison
KK module: Due to its highly integrated structure, low friction coefficient, and high rigidity, it is suitable for precision positioning scenarios (such as semiconductor testing).
Embedded screw module: Medium precision, strong rigidity, but the split structure may cause slight vibration, slightly inferior to KK module.
KK module: High acceleration, suitable for light loads and high-speed reciprocating motion.
Embedded screw module: with strong load capacity but low speed, suitable for stable handling scenarios.
KK module: easy maintenance, no need for frequent oiling, but internal cleaning is difficult.
Embedded screw module: The centralized oil nozzle design makes lubrication and maintenance convenient, and the steel strip can be quickly disassembled and cleaned, suitable for high dust environments.
Summary: How to choose?
Choose KK module: pursue precision equipment with high precision, small size, fast response, and ample budget.
Choose embedded screw module: Industrial environments that require dust prevention, easy maintenance, long travel or moderate load, especially clean room scenarios.
Both types of modules have their own strengths in design: the KK module improves efficiency through "integrated optimization", while the embedded module balances adaptability and cost through "split protection". The actual selection requires a comprehensive evaluation of load, environment, accuracy, and maintenance costs.
