The Difference Between NBR Seal and FKM Seal of the roller bearing
Difference Between NBR Seal and FKM Seal of the roller bearing
differences are as follows:
seal: FKM sealing ring heat resistance characteristics and silica gel, can be
said to be the stage of vulcanized rubber polyurethane elastomer stronger, the
basic type of fluorine rubber number FKM or FPM, its product output can be
long-term in 200℃ application, and perfluoro
ether vulcanized rubber FKM can continue to be applied at 330℃.
seal: higher 100℃ application, from the heat
resistance of NBR sealing ring.
seal: FKM seal has high-quality physical and physical properties, has
advantages in elastic compressive strength and tensile elongation level.
seal: NBR seal has excellent physical reflectivity and production
seal: FKM seal has smooth organic chemical characteristics, it is also at the
present stage of all vulcanized rubber polyurethane elastomers in a variety of
substances with stronger characteristics. Fluorine rubber oil resistant silicon
ether, magnesium chloride oil, crude oil, base oil, double ester oil,
resistance to most of the organic chemistry, inorganic-organic solvent, resistance
to strong oxidizer, drugs, etc., in which fluorine rubber resistance of the
material not only to the following categories: low substructure of the ether,
ester, ketone, and all of the ammonia, amines, chlorosulfonic acid,
hydrochloric acid, ammonium sulfate type of gear oil.
seal: poor cold resistance, poor resistance to reactive oxygen species, poor
dielectric strength, low ductility.
seal: FKM seal has good resistance to weather embrittlement and reactive oxygen
species. The yield of fluoro glue products is still satisfactory after five
years of storage.
seal: NBR seal anti-aging performance is a little poor, general nitrile rubber
product output can be stored for ten years.
Ultra-low temperature characteristics
seal: because the organic chemical structure of FKM itself causes the cold
resistance of FKM is not very excellent.
the specific application of fluorine rubber ultra-low temperature
characteristics are also general, unless the addition of a unique preservative
can make fluorine rubber cold does minus 30 degrees, otherwise, the general
fluorine rubber only does minus 10 degrees.
seal: Generally NBR adhesives can be cold resistant -30℃, and with extremely super cold
resistance nitrile adhesives can be cold resistant -50℃.

roller bearing brief
roller bearing combines the traditional cylindrical roller bearing and
spherical roller bearing configurations. Its proprietary outer race and roller
profiles plus a cylindrical inner ring combine the key attributes of both
bearing types. This unique three-point contact design geometry provides
simultaneous misalignment and axial displacement performance, optimizes contact
stress distribution, and helps promote roller stability. The result is a more
dynamic, more reliable bearing.
roller bearing consists of an inner ring, outer ring, and roller/retainer
assembly. The separable components simplify installation, removal, and
inspection. The retainer holds the rollers in position, creating a single
assembly that prevents the rollers from being damaged during mounting and
dismounting. The inner ring and outer ring can be installed in either
direction, helping to avoid common mounting errors. No special tooling is
required. Three-quarter angle view of the three main ADAPT bearing components

roller bearing Applications
metal industry\'s tough environment places extreme demand on equipment. That
makes maintaining operations and reducing downtime essential in continuous
casters where performance and reliability are critical. The roller
bearing innovative design redefines the preferred choice of bearings for the
float position in strand roll support segments.
roller bearing for Paper Mill Applications
paper dryers to shaker screens and blowers and fans, the roller bearing
outperforms in tough environments. The roller bearing provides a better option
for handling misalignment and axial float.
roller bearing Design Attributes
range: 100 mm to 170 mm bore (3.94 in. to 6.69 in.)
design with a roller retainer to help eliminate roller fallout
full misalignment and axial displacement capabilities
internal geometry optimizes contact stress and roller stability
ISO dimensions simplify interchange with toroidal and spherical roller bearings
static radial capacity for maximum reliability
capability of +/-0.5 degrees
