Product Description

Product Description

Yoke Type Track Rollers are the rolling
mechanisms whose outer ring rolls on a track. 
For example, these track rollers are applied to eccentric roller,
guide roller, rocker arm roller, cam roller and pressure
roller. For that, the outer ring is designed to a wall
thickness so as to be resistible to high load and shock
load. Both spherical outer surface (rolling surface) and
cylindrical outer surface are available for the outer ring.
The spherical outer ring can withstand edge-load acting
on the contact surface between the track and the track
roller, while the cylindrical outer ring (Tail code: X) has
track load capacity greater than the spherical outer ring.

Needle rollers are the load-carrying component of the bearing, and are the one common component of all needle roller bearing types.
These allow the outer and inner rings to rotate almost friction-free. They are most frequently manufactured from a steel alloy.
 

Raceways (if present) serve to guide the rollers within the bearing. These items are commonly manufactured from carbon chromium steel or other alloys to improve hardness, fatigue resistance, and dimensional stability.

 

Bearing cages separate rollers to keep the load evenly distributed around the bearing. They also reduce bearing noise, improve rolling conditions, and prevent sliding. Additionally, they contain rollers within a single assembly. Steel is the most commonly used cage material in needle roller bearings. Plastic cages can be used where operating conditions permit. Lubrication and surface treatments can reduce the amount of heat generated from friction. Some drawn cup needle roller bearings are designed without a cage, and contain a full complement of needle rollers.

Yoke type track rollers (general)The bearings are available with or without an inner ring, with or without axial guidance and in sealed or open versions. Proven areas of application of these products include cam gears, bed ways, conveying equipment and linear guidance systems.
