The NB slide guide GL type realized low noise with a ball cushion embedded between the steel balls and significantly extended lubricant replenishment intervals by the use of fiber sheet. In addition, its compact size as well as high load capacity allows for the size and weight of machinery and other equipment to be reduced.

GL TYPE

NB - Slide guide - 7383 STRUCTURE AND ADVANTAGES

The GL type slide guide consists of a rail with 4 rows of precisely machined raceway groove and a block assembly consisting of the main body, steel balls, ball cushions, a retainer, a fiber sheet, and return caps.

Low Noise:

By incorporating a ball cushion between steel balls, the metal contact between the steel balls is prevented, which allows for a reducion in noise levels. (See the noise data in Fig. A-44, page A-53.)

High Load Capacity and Long Life:

With large-diameter steel balls employed, this slide guide has a higher load rating and a longer life compared to low-noise guides offered by other companies. (See the load rating comparison data in Fig. A-44, page A-53.)

Can Significantly Extend 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 steel balls are positioned at 45
o contact angle so that the load capacity is equal in four directions (above, underneath, right and left).
