OEM Factory for Bicycle Front Wheel Bearings - 381052X2/HC four row tapered roller Bearing – CWL
OEM Factory for Bicycle Front Wheel Bearings - 381052X2/HC four row tapered roller Bearing – CWL Detail:
Depending on their design, four-row tapered roller bearings provide the following main features and benefits:
Long service life
The four-cup design (four separate outer rings) provides optimal load distribution over all four rows of rollers.
Improved wear resistance
In particular,the bearings are made of extremely clean and homogenous steel and undergo a unique heat treatment, which improve the resistance to wear.
Improved sealing performance with less leakage and less frictional heat
The optimized seal design ensures high protection against external contamination but keeps friction and frictional heat low. This seal design also provides a better retention of lubricant, minimizes environmental impact and reduces maintenance costs.
Equal load carrying capacity for sealed and open bearings
The optimized and compact seal design enables identical internal design.
Total bearing interchangeability
Bearings with and without intermediate rings as well as open and sealed bearings are available with identical external dimensions. This allows total bearing interchangeability of current standard design bearings with those without intermediate rings and/or with optimized seal design.
Separable mounting and simpler inspection
Optimized designs without intermediate rings enable to dismount and separate the cage and roller assemblies and seals. This facilitates mounting, dismounting and also maintenance inspection routines.
Axial space-saving and cost-effective solution for roll necks
The roll necks can be relatively short, no separate axial bearings are required and identically designed chocks can be used on both sides of the roll.
Simple axial location on roll necks
Tighter inner ring width tolerances facilitate the tolerancing and dimensioning of surrounding components.
