2-1/2 TYPE E 4-BOLT PILLOW BLOCK

The 2 1⁄2" Type E 4-Bolt Pillow Block Non-Expansion Bearing is Moline Bearing Company part 19341208: 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 11,600 lbf and the static load rating is 54,000 lbf. Maximum speed is 2,100 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 290 in-lbs, and the locking system holds 9,500 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: 8 1⁄2 in (slots allow 8 5⁄16 to 8 11⁄16 in), for 5⁄8 in bolts
  • Bolt spacing across: 1 7⁄8 in
  • Housing base: 10 1⁄2 × 3 1⁄2 in
  • Overall height: 5 1⁄2 in
  • Length through bore: 4 in
  • Shipping weight: 19 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 19341208L (labyrinth seals), 19341208A (single collar), 19341208AL (single collar, labyrinth seals).

Replacement parts

The bearing insert is 39250DE-40634 or NPE39250DEE-401C4, and the housing on its own is Moline Bearing Company part 11401207. Open end cap 18621208 and closed end cap 18620207 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.
