INA Yoke type track rollers NATR12-PPA
with axial guidance, axial plain washers on both sides

Yoke type track rollers can support high radial loads as well as axial loads arising from slight misalignment and skewed running; they are suitable for applications such as cam gears, bed ways and conveying equipment. The NATR-PP type design comes complete with axial guidance and axial plain washers on both sides. 

This design has a cage and is suitable for operating temperatures from -30°C to +100°C, restricted by the grease and the seal material.

Supplementary code in the post code is used to illustrate the bearing of some special structure, placed after the bearing code.
1. A description of the supplementary codes used in the dimension tables
These supplementary codes apply to bearings in existing standards and are part of the bearing designations (see dimension tables), which can not be used for other bearings.
A, B, C, E These symbols have no clear meaning, and are used to represent certain design features as required.
D-Split needle roller and cage assembly
P-bearing side with a sealing ring
PP-bearing with sealing ring on both sides
RS-bearing side with a seal ring
2RS-bearing with sealing ring on both sides
TN-plastic cage
V-sealed bearings
X- bearings and accessories with external dimensions that conform to international standards. This code is only for use during the transition period.
When the structure is generally spherical in shape, X is also indicated as a support roller with a cylindrical roller face and a curve roller.
Z-bearing with a dust cover on one side
2Z-bearing with dust cover on both sides
ZW-needle roller and cage assemblies, double row
2. With a special tolerance and precision bearing the supplementary code
The following codes apply only to certain types of bearings listed in the dimension tables.
P- stands for general dimensional tolerances and geometrical accuracy requirements (no additional designation is required).
P6- Bearings with high dimensional tolerances and geometrical accuracy
P5- Bearings with high dimensional tolerances and geometrical accuracy
P4- Dimensional tolerances and geometrical accuracy require extremely high bearings
C2 - The original radial clearance is less than C0
C0 - Normal original radial clearance (no additional code required)
C3- The original radial clearance is greater than C0
C4 - the original radial clearance greater than C3, for high dimensional accuracy and geometric precision and the original radial clearance is different from the normal clearance of the bearing, the code can be used in combination.
H + ... + ... - No inner ring bearing with narrower tolerance of the inscribed circle diameter, excluding drawn cup needle roller bearings.
G-Needle quality level.
SORT - Diameter classification of the needle in the needle roller and cage assembly, the tolerance limit in microns.
GP- noise-tested bearings.
2S, 3S, S This code is for two or more bearings, installed side by side, the load evenly distributed, the figures in front of the same series of the same size of the selected number of bearings. The bearings or parts are not interchangeable.
3. With a special structural bearing the supplementary code
(1) special bearings and parts
BIR-spherical inner ring raceway
BR-bearing surface by oxidation
AS.- Lubrication holes are available in the outer ring, with additional figures for the number of lubrication holes
ASR.- There are lubrication holes and grooves in the outer ring
EGS-inner ring raceway by turning out, no spiral grinding marks
FPM - G series seal ring made of fluorinated rubber
GS - Vertical bearing housings made of cast steel
IS.- There are lubrication holes in the inner ring
ISR.- There are lubrication holes and oil grooves in the inner ring
PB-SG series of vertical bearings in the rough drill hole
SK-Curved roller with hexagon hole
RGS-inner ring raceway allowance allowance
(2) bearings with special grease lubrication
SM 01 - lubricated with KP2K rolling bearing grease according to DIN 51825 at a temperature range of -30 ° C to + 120 ° C
SM 02 - Lubricate with K3N rolling bearing grease according to DIN51825 at a temperature range of -30 ° C to + 140 ° C
SM 11 - lubricated with KTC2E low temperature grease according to DIN 51825 at a temperature range of -50 ° C to + 80 ° C
SM 27 - lubricated with KH2R high temperature grease according to DIN 51825, temperature range -30 ° C to + 175 ° C
