The BSG Recirculating Ball Slide Guide consists of a block and a guide rail, both having two R-shape raceway grooves machined by precision grinding. The block consists of a main body having raceway grooves and a resin return cap ensuring smooth circulation of balls. These precision steel balls roll in the respective raceway groove with contact at four points. The raceway surface over which the balls roll is an R-shaped groove, offering a large contact area. The Gothic arch groove, where the balls contact the raceway surface at four points, enables the load and moment to be carried in all directions.
Since precision steel balls are used as rolling elements, the rolling resistance is extremely small, ensuring smooth and stable operation. The block is a simple structure, so the slide guide is compact and inexpensive. Its compactness and light weight also make this product optimum for linear operation at high speed.
Stainless steel ball slide guide type (BSGSW) is available. The BSGSW type uses stainless steel for the block and guide rail, thus having superior corrosion resistance.
