Slide linear guide SGL series

with ball bearingstainless steelfor heavy loads

The NB SLIDE GUIDE SGL type is a linear guide 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. The NB SLIDE GUIDE SGL type consists of a rail with 4 rows of precisely machined raceway grooves and a block assembly. The block assembly consists of the main body, ball elements, retainers, and return caps. High Load Capacity and Long Life The use of relatively large ball elements and raceway grooves machined to a radius close to that of the ball elements increases the contact area resulting in a high load capacity and a long travel life. Dust Prevention Side-seals are provided as a standard. To improve the dust prevention characteristics, under-seals, double-seals, scrapers, bellows and special rail mounting caps are also available. Low Friction Because a 4-row/2-point contact design is used, low friction and stable motion characteristics are achieved even under preloaded conditions. Fiber Sheet Extends Lubricant Replenishment Intervals 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. Omni-Directional Load Capacity The ball elements are positioned at 45° contact angle so that the load capacity is equal in four directions (above, below, right and left). Absorption of Mounting Dimensional Error Because the ball elements are positioned to increase their self-aligning characteristics, the dimensional error caused during installation is absorbed.
