3-1/2 M2000 4-BOLT PILLOW BLOCK NON-EXPANSION WITH LABYRINTH SEALS

The 3 1⁄2" M2000 4-Bolt Pillow Block Non-Expansion Bearing with Labyrinth Seals is Moline Bearing Company part 19241308L: a mounted spherical roller bearing in the non-expansion position. It is fitted with a balanced steel and Teflon labyrinth 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, which gives it high load capacity and the most misalignment tolerance of Moline's lines. M2000 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 2,200 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 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

  • Base to center height: 3 3⁄4 in
  • Bolt hole centers: 10 in (slots allow 9 1⁄4 to 10 3⁄4 in), for 3⁄4 in bolts
  • Bolt spacing across: 2 in
  • Housing base: 13 × 3 7⁄8 in
  • Overall height: 7 1⁄2 in
  • Length through bore: 4 1⁄32 in
  • Overall unit width: 4 9⁄16 in
  • Shipping weight: 38 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 19141308L.
  • 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.
  • 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 19241308 (triple-lip contact seals), 19241308G (garter seals), 19241308DG (double collar, garter seals), 19241308DL (double collar), 19241308D (double collar, triple-lip contact seals).

Replacement parts

The bearing insert is SLA18-308. Open end cap 18621308 and closed end cap 18620307 fit this housing.

Applications

M2000 units are the choice where a high-capacity, self-aligning bearing is needed and shaft expansion or misalignment is expected. Moline Bearing Company lists conveying, screening, air handling, paper and forestry, and food processing among the industries that run them. It is directly interchangeable with other collar-mounted spherical roller bearings in single-piece housings, including Moline's M3000 line.
