NA-type bearings come with a standard long stud and metal seal. Overall length is longer than other types as the bearing is fastened between two nuts. Two variations are available – concentric, where the mounting stud is aligned with the axis of rotation, and eccentric – allowing preload adjustments at the user’s discretion.

NAS-type bearings come with a standard short stud and nitrile rubber seal. High dust resistance is achieved by employing a contact seal. Overall length, including the mounting stud, is short, enabling compact design. Two variations are available – concentric, where the mounting stud is aligned with the axis of rotation, and eccentric – allowing preload adjustments at the user’s discretion.

NAL-type bearings come with a standard long stud and nitrile rubber seal. High dust resistance is achieved by employing a contact seal. The mounting stud is long, enabling freedom in design. Lock nuts are included as a standard accessory. Two variations are available – concentric, where the mounting stud is aligned with the axis of rotation, and eccentric – allowing preload adjustments at the user’s discretion.

NAB-type bearings come with a standard short stud and nitrile rubber seal. High dust resistance is achieved by employing a contact seal. A relief machined into the mounting stud enables the bearing to be directly screwed into a tapped hole. NAB-type bearings are only available in concentric design.

GS-type rails are available in 4 different sizes, the maximum length being 1410mm. Butt joints can also be specified to create even longer rails. As rail and spacer have been integrated, mounting is straightforward. The V-shaped edge has undergone induction hardening, but additional processing is possible as hardening has not been applied to the center section. Three grade variations are available for different usage environments: “C” is in a cold-drawn state; “N” has had precision polishing applied only to its V edge (raceway surface); and “P” has had all surfaces polished. A black oxide finish has been applied to all non-polished areas.

GF-type rails are available in 5 different sizes, the maximum length being 1410mm. Butt joints can also be specified to create even longer rails. Overall height is lower than the height of GS-type rails, enabling compact design. The V-shaped edge has undergone induction hardening, but additional processing is possible as hardening has not been applied to the center section. Three grade variations are available for different usage environments: “C” is in a cold-drawn state; “N” has had precision polishing applied only to its V edge (raceway surface); and “P” has had all surfaces polished. A black oxide finish has been applied to all non-polished areas.

These are unit products consisting of bearings, guide rail and mounting table. Preload adjustments are performed prior to shipping, thereby allowing installation immediately on delivery.
