Extra Wide Recirculating Ball Slide Guides

The BSGW Extra Wide type 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. With its increased number of rolling elements and increased width, this unit can replace the use of two linear guides. Stiffness in regard to moment load is increased, thus creating an effective compact linear motion mechanism.

1.    Smooth and Stable operation. Since precision steel balls are used as rolling elements, the rolling resistance is extremely small, ensuring smooth and stable operation.

2.    Compact, lightweight, and low price. 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.

3.    High load capacity utilizing the R-shaped groove. The raceway surface over which the balls roll is an R-shaped groove, offering a large contact area. Therefore, the product features a large load capacity and a long effective life.

4.    Four-point contact to carry load and moment in all directions. 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.

Stainless steel type (BSGSW) is available. The BSGSW type uses stainless steel for the block and guide rail, thus having superior corrosion resistance.
