2-1/4 ME2000 2-BOLT PILLOW BLOCK NON-EXPANSION DOUBLE COLLAR WITH LABYRINTH SEALS

The 2 1⁄4" ME2000 2-Bolt Pillow Block Non-Expansion Bearing with Double Collar Insert and Labyrinth Seals is Moline Bearing Company part 29221204DL: a mounted spherical roller bearing with Type E dimensions in the non-expansion position. It is fitted with a balanced steel and Teflon labyrinth 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 22,400 lbf and the static load rating is 26,500 lbf. Maximum speed is 3,800 rpm with the balanced steel and Teflon labyrinth seal fitted, and the seal is rated for 0° to 350°F. The insert accepts up to 1.5° of angular misalignment. Set screws torque to 290 in-lbs, and the locking system holds 2,700 lbf of radial load before the insert slips on the shaft. The grease fitting is 1/8-27 NPT.

Mounting dimensions

  • Base to center height: 2 3⁄4 in
  • Bolt hole centers: 7 7⁄8 in (slots allow 7 1⁄8 to 8 5⁄8 in), for 5⁄8 in bolts
  • Housing base: 10 1⁄2 × 2 7⁄8 in
  • Overall height: 5 11⁄16 in
  • Length through bore: 4 5⁄16 in
  • Shipping weight: 17.5 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. The matching expansion unit for this shaft size is 29121204DL.
  • Balanced Steel and Teflon Labyrinth Seal. A labyrinth seal combining steel with a Teflon element, adding chemical resistance and a wider temperature range to a non-contact design.
  • 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 29221204DG (garter seals), 29221204D (triple-lip contact seals), 29221204 (single collar, triple-lip contact seals), 29221204G (single collar, garter seals), 29221204L (single collar).

Replacement parts

The bearing insert is SLAA11-204. Open end cap 18621203 and closed end cap 18620203 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.
