2-1/2 M2000 4-BOLT PILLOW BLOCK EXPANSION WITH DOUBLE COLLAR INSERT

The 2 1⁄2" M2000 4-Bolt Pillow Block Expansion Bearing with Double Collar Insert is Moline Bearing Company part 19141208D: a mounted spherical roller bearing in the expansion position. It is fitted with a standard triple lip 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 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 37,768 lbf and the static load rating is 48,559 lbf. Maximum speed is 1,800 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 290 in-lbs, and the locking system holds 4,000 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 1⁄4 in (slots allow 6 7⁄8 to 7 5⁄8 in), for 1⁄2 in bolts
  • Bolt spacing across: 1 3⁄4 in
  • Housing base: 9 1⁄4 × 3 1⁄4 in
  • Overall height: 5 11⁄16 in
  • Length through bore: 4 5⁄16 in
  • Shipping weight: 17 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 19241208D.
  • Standard Triple Lip Contact Seal. Three lips in series for demanding contamination exclusion, at the cost of more running friction and heat.
  • 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 19141208L (single collar, labyrinth seals), 19141208 (single collar), 19141208DG (garter seals), 19141208DL (labyrinth seals), 19141208G (single collar, garter seals).

Replacement parts

The bearing insert is SLA13-208. Open end cap 18621208 and closed end cap 18620207 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.
