1-3/8 TYPE E 4-BOLT FLANGE

The 1 3⁄8" Type E 4-Bolt Flange Non-Expansion Bearing is Moline Bearing Company part 19311106: a mounted tapered roller bearing in the non-expansion position. It is fitted with a standard V-Guard contact seal and a double collar, set screw locking insert, in a solid Class 30 cast iron housing with a standard painted finish.

It carries a genuine Timken® Enhanced DEE tapered roller insert: case-hardened rollers and races made from vacuum-degassed steel, with a double-extended inner race, rated for high radial and thrust loads and slight angular misalignment. The housing is machined to close tolerances, and the unit is made, machined and assembled in the USA.

It ships assembled, adjusted, sealed and pre-lubricated with lithium complex grease, so it mounts straight from the box with no adjustment or cleaning.

Ratings

The dynamic load rating is 3,810 lbf and the static load rating is 15,760 lbf. Maximum speed is 3,200 rpm with the standard V-Guard contact seal fitted, and the seal is rated for 0° to 250°F. The insert accepts up to 0.05° of angular misalignment. Set screws torque to 165 in-lbs, and the locking system holds 3,100 lbf of radial load before the insert slips on the shaft. The grease fitting is 1/8-27 NPT.

Mounting dimensions

  • Bolt hole centers: 3 1⁄2 in
  • Bolt size: 1⁄2 in
  • Flange: 4 5⁄8 × 4 5⁄8 in
  • Length through bore: 3 in
  • Shipping weight: 6.7 lb

The full dimension table and the datasheet drawing are above.

This configuration

  • Non-Expansion. This position holds the shaft axially. Use one non-expansion bearing per shaft to locate it lengthwise.
  • Standard V-Guard Contact Seal. Moline's standard contact seal, with a lip riding on the insert to exclude contamination.
  • Double Collar. Two locking collars share the clamping load, improving holding power under reversing rotation or shock.
  • Set Screw Locking. Set screws in the collar bite into the shaft. Simple and widely used; best where rotation is in one direction.

The same size is also built as 19311106A (single collar), 19311106AL (single collar, labyrinth seals), 19311106L (labyrinth seals).

Replacement parts

The bearing insert is 19137DE or NPE19137DEE-401C4, and the housing on its own is Moline Bearing Company part 11101107. Open end cap 18621106 and closed end cap 18620107 fit this housing.

Applications

Type E units are specified where radial loads, thrust loads or both are high and misalignment is minimal. Moline Bearing Company lists conveying, screening, cranes, mining, forestry, oil, gas, power generation and aggregate among the industries that run them. It is dimensionally interchangeable with comparable Type E units, including Moline's Split E1000, ME2000 and ME3000 lines.
