Profile Guide Rails are linear motion bearings which incorporate a linear guides rail (inner race) with precision ground grooves along the entire length of rails, combined with a precision machined carriage block (outer race) with matched rolling elements tracking the inner race grooves. This combination of precision grooves and matched carriage provides for high-load capacities, smooth motion, long predictable life in a small compact work envelope.
The SEB type slide guide is a linear motion bearing in which the ball elements roll along two tracking grooves. This is the smallest and lightest slide guide series offered by Nippon Bearing. The compact design allows for the size and weight of machinery and other equipment to be reduced.
Structure and Advantages
The SEB type slide guide consists of a rail with precisely machined raceway grooves and a block assembly consisting of the main body, return caps and ball elements. Side-seals are available as an optional feature.
The NB SER type slide guide is a linear motion bearing utilizing the rotational motion of precision rollers placed in two rows. Despite its compact shape, it can be used in various applications requiring high load capacity.
Structure and Advantages
The NB SER type slide guide consists of a rail with two precision-machined raceway grooves and a block assembly. The block assembly consists of a main body, rollers, and bottom roller retainers. All of these components are made of metallic materials.
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 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.
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.
