1 For the supported models, see the table of options by model number on. For the M block dimension with QZ attached, see to. For notes regarding how to handle the QZ, see. feeds the right amount of lubricant to the raceway on the M rail. This allows an oil film to continuously be formed between the rolling element and the raceway, and drastically extends the lubrication and maintenance intervals. The structure of consists of three major components: (1) a heavy oil-impregnated fiber net (function to store lubricant), (2) a high-density fi ber net (function to apply lubricant to the raceway) and (3) an oil-control plate (function to adjust oil fl ow). The lubricant contained in is fed by the capillary phenomenon, which is used also in felt pens and many other products, as the fundamental principle. M Guide () Case (1) Heavy oil-impregnated fiber net (End seal) (2) High-density fiber net Ball Appearance Drawing (3) Oil control plate Flow of lubricant Structural Drawing Ball cage Features Since it supplements an oil loss, the lubrication maintenance interval can be significantly extended. Eco-friendly lubrication system that does not contaminate the surrounding area since it feeds the right amount of lubricant to the ball raceway.

2 Significantly Extended Maintenance Interval Attaching helps extend the maintenance interval throughout the whole load range from the light load area to the heavy load area. Heavy load Grease lubrication only 465km Grease + 962km M Guide: HSR35R1SS Condition Heavy load Medium load ight load oad 18.6kN 9.3kN 1.4kN Speed 50m/min 50m/min 300m/min Grease: 2cc/1 M block - initial lubrication only : 5cc 2/1 M block - initial lubrication only Medium load ight load Grease + Grease km 30000km Distance traveled (km) M Guide Running Test without Replenishment of ubricant Effective Use of ubricant Since the lubricator feeds the right amount of lubricant to the ball raceway, lubricant can be used efficiently.
