3-7/16 ME2000 4-BOLT FLANGE EXPANSION DOUBLE COLLAR WITH GARTER SEALS

The 3 7⁄16" ME2000 4-Bolt Flange Expansion Bearing with Double Collar Insert and Garter Seals is Moline Bearing Company part 29111307DG: a mounted spherical roller bearing with Type E dimensions in the expansion position. It is fitted with a spring loaded garter 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 SKF or Timken spherical roller insert in a solid cast iron housing with an integrated center support, so it gives spherical-roller misalignment and expansion capability in a Type E footprint. ME2000 housings are made in the USA, and the units are assembled here.

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 56,900 lbf and the static load rating is 76,400 lbf. Maximum speed is 800 rpm with the spring loaded garter seal fitted, and the seal is rated for 0° to 250°F. The insert accepts up to 1.5° of angular misalignment. Set screws torque to 1,325 in-lbs, and the locking system holds 6,800 lbf of radial load before the insert slips on the shaft. The grease fitting is 1/8-27 NPT.

Mounting dimensions

  • Bolt hole centers: 7 in
  • Bolt size: 3⁄4 in
  • Flange: 9 1⁄4 × 9 1⁄4 in
  • Height above mounting surface: 5 5⁄16 in
  • Length through bore: 5 3⁄16 in
  • Shipping weight: 51.5 lb

The full dimension table and the datasheet drawing are above.

This configuration

  • Expansion. This position lets the shaft move lengthwise as it heats and grows. Pair it with a non-expansion bearing at the other end. The matching non-expansion unit for this shaft size is 29211307DG.
  • Spring Loaded Garter Seal. A contact seal with a garter spring keeping constant lip pressure on the shaft, holding its seal as the lip wears.
  • 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 29111307D (triple-lip contact seals), 29111307DL (labyrinth seals), 29111307 (single collar, triple-lip contact seals), 29111307G (single collar), 29111307L (single collar, labyrinth seals).

Replacement parts

The bearing insert is SLAA18. Open end cap 18621307 and closed end cap 18620307 fit this housing.

Applications

ME2000 units are specified where a Type E footprint needs more misalignment or expansion capability. Moline Bearing Company lists conveying, screening, air handling, laundries, food processing, and paper and forestry among the industries that run them. It is dimensionally interchangeable with competitive spherical roller bearing units in Type E dimensions, including Moline's Split E1000 and ME3000 lines.
