Yoke Type Track Rollers - NATRNATV Series

Product Description

The pulleys are available with a flat runner surface or a crowned one, which can be designed according to customer’s application. They can roll directly on the tray under heavy load and shock load. They are greased for life. Under normal operating conditions, they are maintenance-free, while they should be re-lubricated under severe working condition to prolong the working lifespan.Yoke type track rollers can support high radial loads and axial loads arising from misalignments and skewed running and are suitable for cam drives, slideways, conveying equipment etc. The bearings are available with or without an inner ring as well as in open and sealed versions.

MBY support rollers are basically needles or cylindrical roller bearings with a thick-walled outer race. The rollers are available either with a flat runner surface or crowned runner surface, which can be designed according to customer's application. With this outer race, the support rollers are able to roll directly in the raceway and bear a heavy load rating. The crowned runner surface should always be used where angular misalignments with respect to the track expected and edge stresses kept to a minimum. They are ready-to-fit units, filled with grease and are suitable for all types of cam drives, tracks, conveyor systems and etc. The support rollers can be divided into ones with axial guidance or without axial guidance. And from sealing structure, they can be divided into open type and sealed type. 

Applications of MBY support rollers: 
Automotive equipments;
Material handling equipments;
Mining & metals equipments;
Linear motion guide equipment;

Advantages of MBY support rollers: 
Optimized structure and reliable quality;
Modifying the contacting surface logarithmically to reduce the contact stress;
Used in wide range with different precision standards;
Reducing the fitting and maintaining costs with the ready-to-fit units;
Special oil supplying system and easily operating;
With thick-walled outer and can take up high radial load especially;
With axial guidance, support rollers can bear the axial impact load even at high speed;
