Tolerance
In common cases,the precision of the dimensions,shape and the rotation of this yoke type track roller is P0 grade.The outer diameter tolerance of the yoke type track roller with an arc outer diameter is 0 to -0.05mm,the width tolerance of NATR,NATV,NUTR bearings is h12.
Center adjustability
The yoke type track roller with diameter of cylindrical shape have very small center adjustability.With low load,the center adjustability is 3-4'which with middle and heavy load,it is 5-7'.The yoke type track with diameter of arc shape have a center adjustability of 15-20'.For bigger angle variation,the edge effect will increase with the different loads.This will decrease the life of the bearing.
RSTO and STO type yoke type track rollers
RSTO series yoke type track rollers RSTO type,without inner ring,can directly run on the quenched shaft.STO type has inner rings,its inner ring,outer ring and the combinative needle roller retainer assembly can be fitted separately.Because RSTO and STO type yoke type track rollers have no retaining edges and the end retaining rings,axial guiding is needed in fitting.the guiding surface must be precisely machined at least.

RNA22...2RS,NA22...2RS type yoke type track rollers
The diameter of such rollers is the same as STO series rollers but a little wider.Its double face sealed structure ensures no maintenance requested.The operational temperature range is
-20°C-120°C.When fitting the yoke type track rollers without inner rings (RNA22...2RS)series,noice no damage to the sealing rings should occur.The outer ring needs end face guidance.

NATR and NATR...PP type yoke type track rollers
NATR series roller contains outer ring,inner ring,needle retainer assembly and the retaining rings which are pressed and fixed by the two sides of inner ring.NATR...PP series has an additional sealing ring.This kind of yoke type track rollers have huge lubricant storage space,so they can be used for long period without re-grease.
NATV and NATV...PP type yoke type track rollers
NATV series yoke type track roller is basically the same as NATR series.The only difference is that NATV is full complement needle roller type.Therefore it can sustain heavier load under low speed.Frequent lubricating should be noticed.NATV...PP is a series with sealing ring structure.
