Miniature carriage units – corrosion-resistant with cylindrical roller flat cages

Preload Miniature carriage units RMWE..VA are preloaded (Table 1). Increasing the preload has the effect of increasing: â–  the rigidity
Locating face Set no.Set no. â–  the moment load carrying capacity â–  the guidance accuracy.However, preload also influences the displacement resistance and the operating life of cage guidance systems! Table 1 ·Preload class

156 192 Location of guideways and carriages The defined locating face on the carriage should be used in thedesign (Figure 2) â–  the locating face is on the opposing side to the marked face.If high rigidity and high load carrying capacity are required, theguidance elements should be abutted on both sides against locating faces of the adjacent construction (Figure 3).For high loads, the load carrying capacity of the fixing screws must be checked!If fixing is to be carried out in accordance with DIN 645-2, smaller screws should be used in conjunction with appropriate support washers.In order to avoid location defects, the holes in the adjacent construction must be carefully deburred.The counterbores of the guideway fixing holes have sharp edges! Risk of injury!The carriage must not be removed from the guideway! Incorrect fitting or dismantling can damage the cage!If corrosion-resistant fixing screws are used, their lower tensile strength and lower tightening torques must be taken into consideration!After the guideways have been fitted, the counterbores must be closed off using plastic closing plugs in order to protect against contamination (special design, page 11) (Figure 4)
