INA NUTR and PWTR Track Roller Difference

[Michael Zhang]

NUTR Design: Outer Ring, Inner Ring, Cylindrical Roller, Side Plate
and Shield
PWTR: Outer Ring, Inner Ring, Cylindrical Roller, Side Plate and
Framework Seal

Designs are similar, but NUTR design have shield for dustproof; while
PWTR design is framework seals for dustproff, waterproof and prevent
impurities. Moreover, PWTR designs will have much better axial load
rating than NUTR designs, because PWTR design have a rib in the middle
of inside raceway of outer ring.

In addition, both of NUTR and PWTR designs will have superfinishing
raceway and cylindrical roller to decrease noise and rotation
performance.
