The GL type slide guide consists of a rail with 4 rows of precisely machined raceway groove and a block assembly consisting of the main body, steel balls, ball cushions, a retainer, a fiber sheet, and return caps. > By incorporating a ball cushion between steel balls, the metal contact between the steel balls is prevented, which allows for a reducion in noise levels. (See the noise data in Fig. A-44, page A-53.) > With large-diameter steel balls employed, this slide guide has a higher load rating and a longer life compared to low-noise guides offered by other companies. (See the load rating comparison data in Fig. A-44, page A-53.) > A lubricant-containing fiber sheet incorporated in the block supplies appropriate amount of lubricant to the raceway grooves at appropriate intervals, which can significantly extend the lubricant replenishment interval. > The steel balls are positioned at 45 > o contact angle so that the load capacity is equal in four directions (above, underneath, right and left). > Figure A-50 Structure of GL type Slide Guide return capblockside seal under-sealball cushionsguide railsteel ballsretainer fiber sheet A-42 >
