Needle Roller Cages

Needle Roller Cages for General Usage are bearings that display excellent rotational performance. Their specially shaped cages with high rigidity and accuracy, precisely guide the needle rollers. Since needle rollers with extremely small dimensional variations in diameter are incorporated and retained, Needle Roller Cages for General Usage are useful in small spaces when combined with shafts and housing bores that are heat treated and accurately ground as raceway surfaces. They are suitable for the severe conditions of small and medium-sized engine and compressor connecting rods. They withstand rapid variations in loads and load directions, high temperatures and low lubrication.

Shell Type Needle Roller Bearings

Shell Type Needle Roller Bearings are lightweight with the lowest sectional height among needle roller bearings with outer ring, because they employ a shell type outer ring made from a thin special-steel plate which is accurately drawn, carburized and quenched. Since these bearings are press-fitted into the housing, no axial positioning fixtures are required. They are ideal for use in mass-produced articles that require economy. The shaft is used as the raceway. The needles and the cage are not removable. The drawn cup needle roller bearings fit into compact designs due to their thin outer ring.

Machined Type Needle Roller Bearings

Machined Type Needle Roller Bearings have an outer ring made by machining, heat treatment, and grinding. The outer ring has stable high rigidity and can be easily used even for light alloy housings. These bearings are available in various types and optimally selectable for different conditions such as heavy loads, high-speed rotation and low-speed rotation. They are most suitable for general-purpose applications.

Needle Roller Bearings with Separable Cage

In Needle Roller Bearings with Separable Cage, the inner ring, outer ring and Needle Roller Cage are combined, and they can be separated easily. This type has a simple structure with high accuracy. In addition, the radial clearance can be freely selected by choosing an assembly combination. These bearings have excellent rotational performance, because Needle Roller Cages are used. The outer ring cannot regulate the axial displacement of the needle roller and cage assemblies, this is why the bearing must be mounted so that the needle roller and cage assemblies are guided by the shaft or housing.

Roller Bearings

Roller Bearings, in which rollers are incorporated in double rows, are non-separable heavy-duty bearings. They can withstand not only radial loads but axial loads as well, which are supported at the contacts between the shoulders of inner and outer rings and the end faces of rollers. Therefore, they are most suitable for use at the fixing side of a shaft.

Axial Cylindrical Roller and Needle Roller Bearings(Thrust Bearings)

Thrust Bearings consist of a precisely made cage and rollers, and can receive axial loads. They have high rigidity and high load capacities and can be used in small spaces.Thrust Needle Roller Bearings use needle rollers, while Thrust Roller Bearings use cylindrical rollers.

Cam Followers

Cam Followers are bearings with a stud incorporating needle rollers in a thick walled outer ring. They are designed for outer ring rotation, and the outer rings run directly on mating track surfaces. Various types of Cam Followers are available. They are widely used as follower bearings for cam mechanisms and for linear motions.

Combined Type Needle Roller Bearings

Combined Type Needle Roller Bearings are combinations of a radial bearing and a thrust bearing. Caged Needle Roller Bearings are used as radial bearings and Thrust Ball Bearings or Thrust Roller Bearings are used as thrust bearings. They can be subjected to radial loads and axial loads simultaneously.

Roller Followers

Roller Followers are bearings in which needle rollers are incorporated in a thick walled outer ring. These bearings are designed for outer ring rotation, and the outer rings run directly on mating track surfaces. They are used as follower bearings for cam mechanisms and for linear motions.

Crossed Roller Bearings

Crossed Roller Bearings are high-rigidity and compact bearings with their cylindrical rollers alternately crossed at right angles to each other between inner and outer rings. A single Crossed Roller Bearing can take loads from any directions at the same time such as radial, thrust, and moment loads. These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc. which require compactness, high rigidity and high rotational accuracy.

Radial and Axial Plain Bearings

Spherical Bushings are self-aligning spherical plain bushings, which have inner and outer rings with spherical sliding surfaces. They can take a large radial load and a bi-directional axial load at the same time. They are divided into steel-on-steel types that are suitable for applications where there are alternate loads or shock loads, and maintenance-free types which require no lubrication.

Rod Ends

Rod Ends are compact self-aligning spherical plain bearings which can support a large radial load and a bidirectional axial load at the same time. Rod Ends have either a female thread in the body or a male thread on the body, so they can be easily assembled onto machines. Rod Ends are used in control and link mechanisms in machine tools, textile machines, packaging machines, etc.
