Reduced wear from yoke and stud type
track rollers
Ina has introduced a new range of yoke and stud type track rollers, the series NATR/NATV and KR/KRV, that offer significantly increased benefits over their predecessors.
Ina has introduced a new range of yoke and stud type track rollers, the series NATR/NATV and KR/KRV, that offer significantly increased benefits over their predecessors Representing a further significant advance in rolling bearing technology, the new series includes the "optimised Ina profile", a patented design for the outer ring profile that gives a substantial reduction in Hertzian pressure as well as limiting edge stresses under tilting

Guide to guidance systems and accessories includes both linear recirculating roller bearing and ball bearing guideway assemblies, as well as complete linear guidance systems.
Giving reduced wear and longer service life, the "optimised Ina profile" was first applied to track rollers based on cylindrical rollers, and has now been extended to needle roller type track rollers.
Greatly improved behaviour under skewed running and tilting is achieved by track rollers with contact seals now having a plastic axial plain washer to reduce friction, giving a positive effect on grease consumption.
To allow easier fitting, a hexagonal socket is incorporated in both ends of the stud type track rollers, making it possible to use an allen key on the flanged end whilst tightening the fixing nut on the threaded stud end.
Relubrication is now possible from either end, thanks to a lubrication nipple or, for larger sizes, a lubrication adapter is available that allows connection to a central lubrication system.
Conforming to draft standard ISO/CD 7 063, and available in outside diameters from 16mm to 90mm, the new track rollers were developed as a result of design innovations, reflecting the INA philosophy of refining existing products for improved performance and customer benefits.
