  Angular Contact Enduro Bearings

Angular Conatct Bearings

Enduro produce a line of Angular Contact (A/C) cartridge bearings specifically designed for hubs. In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction and minimize wear. Wheel play can be adjusted out of the hub providing a more stable wheel, and making it easier to adjust disc brakes while still spinning freely.

  • LLB - Is a double lip seal making light contact, and also rides in a groove making a labrinth seal (reducing friction for less rolling resistance whilst maintaining a good seal, preventing contaminating particles entering the raceways)
  • Red seal indicates preload side - 5-10 lbs of preload required
  • Black Seal indicates side to go against frame
  • 15 Degree Contact Angle

Stainless Steel 440C steel balls and raceways:

Enduro Bearings manufactures some series of bearings using 440C stainless steel balls and races. This material provides maximum corrosion resistance in applications and environments where critical. Depending on the application, they are designed to ABEC-3 or ABEC-5 tolerances. Stainless steel has 20% less load capacity than the 52100 chromium steel, used in most of our bearings, but with far superior corrosion resistance

The ABEC 5 Standard

To meet the ABEC-5 standard, bearing design must pass all tests, which include noise testing at high RPM, extremely close tolerances for I.D. and O.D., roundness of ball, trueness of the races and micro surface finishes of balls and races.

Graphite/Nylon Ball Retainers

Nylon with graphite retainers are virtually frictionless while providing constant lubrication.

More Information
Manufacturer Part Number = SMRA 2437 LLB
Weight kg = 0.031000
Brand = ENDURO
UPC = 811780020702
Precision Grade = ABEC 5
Inside Diameter = 24mm
Outside Diameter = 37mm
Width = 7mm
Seals or Shields = LLB = This is a Nitrile material rubber with a steel insert. Rather than the standard 2RS type seal, by machining a groove into the inner race where the seal can rotate with better efficiency and less rolling resistance. Rather than one thick seal lip rubbing on a blunt surface, LLB type utilizes two razor thin sealing lips riding in the groove with light contact. The outside lip keeps the water and contaminates out, while the inner seal retains the grease for smooth function and long intervals between servicing.
Static Capacity (lbs) = 726
Material = Stainless Steel
