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.
With the retained balls, the SEBS "B" type block is able to be removed from the guide rail, simplifying its installation and resulting in lower assembly costs.
By using Stainless Steel for the return caps, the SEBS "BM" type is constructed from only Stainless Steel making this the ideal choice for special environments such as high temperature, clean room, or vacuum applications.
A wide block "WA" type, a long block "AY" type, and a wide/long block "WAY" type are moment resistant slide guides available. One of these should be suitable for any demanding operating condition.
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 wide block design (WA Type) has an extremely high moment loading capacity. This will allow for single shaft designs in the most hostile environment applications.
Since all the components for the SER type guide are made of metallic materials, stainless steel provides excellent corrosion and thermal characteristics. The SERS type slide guide is ideal for clean-room or vacuum applications.
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 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.
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.
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.
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.
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.
