In this series, the ball row is placed at a 45 degree contact angle. The rated load is uniformly applied to the linear moving block in radial, reverse radial, and lateral directions. Due to this feature, the linear motion guide rail series can be implemented in all directions. As this is a global series, it offers a variety of sizes to accommodate a variety of applications from large to small. Our HSR series includes HSR8, HSR10, HSR12, HSR15, HSR20, HSR25, HSR30, HSR35, HSR45, and HSR55 rails, with block lengths ranging from 160 millimeters to 1600 millimeters.

In many industrial applications, cylindrical roll bearings (CRB) play an indispensable role. From precision gears for robots and railway machinery, to geared motors for stationary machinery, to gearboxes for mobile devices and speed multipliers for wind turbines, CRBS support a wide range of loads with their superior performance.The main feature of CRBS is their ability to withstand high radial loads. With careful design, the shoulders of the inner and outer rings can be evenly distributed and thus able to withstand axial loads.

Providing linear to curved HRW guides is an ideal choice for micro to large machine tools. This high-precision guide rail series includes: HRW14LR, HRW17, HRW21, HRW27, HRW50, HRW12LR. Due to its low center of gravity, wide guide rail, and low overall height, the model can be used in areas that require space savings. This product is also suitable for compact and heavy-duty applications, as it has high rigidity in all directions and does not require reinforced side support.
