3 ME2000 2-BOLT PILLOW BLOCK EXPANSION

The 3" ME2000 2-Bolt Pillow Block Expansion Bearing is Moline Bearing Company part 29121300: a mounted spherical roller bearing with Type E dimensions in the expansion position. It is fitted with a standard triple lip contact seal and a single 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 40,545 lbf and the static load rating is 46,800 lbf. Maximum speed is 1,600 rpm with the standard triple lip contact 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 620 in-lbs, and the locking system holds 4,200 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: 3 1⁄8 in
  • Bolt hole centers: 8 13⁄16 in (slots allow 7 7⁄8 to 9 3⁄4 in), for 3⁄4 in bolts
  • Housing base: 12 × 3 in
  • Overall height: 6 5⁄16 in
  • Length through bore: 3 5⁄8 in
  • Overall unit width: 3 7⁄8 in
  • Shipping weight: 23.9 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 29221300.
  • Standard Triple Lip Contact Seal. Three lips in series for demanding contamination exclusion, at the cost of more running friction and heat.
  • Single Collar. One locking collar secures the insert to the shaft. Standard for unidirectional rotation and steady loads.
  • 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 29121300G (garter seals), 29121300L (labyrinth seals), 29121300D (double collar), 29121300DG (double collar, garter seals), 29121300DL (double collar, labyrinth seals).

Replacement parts

The bearing insert is SLA15-300, and the housing on its own is Moline Bearing Company part 11251215. Open end cap 18621215 and closed end cap 18620215 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.
