55MM ME2000 2-BOLT PILLOW BLOCK NON-EXPANSION WITH GARTER SEALS

The 55 mm ME2000 2-Bolt Pillow Block Non-Expansion Bearing with Garter Seals is Moline Bearing Company part 29221055G: a mounted spherical roller bearing with Type E dimensions in the non-expansion position. It is fitted with a spring loaded garter 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 22,400 lbf and the static load rating is 26,500 lbf. Maximum speed is 1,300 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 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 1⁄2 in
  • Bolt hole centers: 7 3⁄8 in (slots allow 6 11⁄16 to 8 in), for 5⁄8 in bolts
  • Housing base: 9 5⁄8 × 2 5⁄8 in
  • Overall height: 5 in
  • Length through bore: 3 1⁄8 in
  • Overall unit width: 3 5⁄16 in
  • Shipping weight: 11.8 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 29121055G.
  • 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.
  • 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 29221055 (triple-lip contact seals), 29221055L (labyrinth seals), 29221055DG (double collar), 29221055DL (double collar, labyrinth seals), 29221055D (double collar, triple-lip contact seals).

Replacement parts

The bearing insert is SLA11-055.

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.
