SGL Type
The SGL slide guide is a linear motion bearing utilizing the rotational motion of ball elements along four rows of raceway grooves. It can be used in various applications due to its compactness and high load capacity.
Structure and Advantages
SGL slide guides consist of a rail with four precisionmachined raceway grooves and a block assembly. The block assembly consists of the main body, ball elements, retainers, and return caps.
The use of larger ball elements and a raceway with grooves machined to a radius close to that of the ball elements increases the area of the contact surface. The results are load capacity and provides longer life.
Because a 4-row/2-point contact design is used, low wear and stable motion characteristics are achieved even under a pre-loaded conditions.
The ball elements are positioned at 45contact angle so that the load capacity is equal in four directions (above, underneath, right and left).
Because the ball elements are positioned to increase their self-aligning characteristics, the dimensional error caused during installation is absorbed.
The rail and block assembly may be Raydent treated to increase the corrosion resistance. This treatment is standardized with the symbol "RD", and suitable for use in clean room applications.
Side seals are provided as a standard. To improve the dust prevention characteristics, underseals and special rail mounting caps are also available.
