3-1/2 M2000 PILOTED FLANGE EXPANSION WITH DOUBLE COLLAR INSERT & GARTER SEALS

The 3 1⁄2" M2000 Piloted Flange Expansion Bearing with Double Collar Insert and Garter Seals is Moline Bearing Company part 19131308DG: a mounted spherical roller bearing in the expansion position. It is fitted with a spring loaded garter 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 56,900 lbf and the static load rating is 76,400 lbf. Maximum speed is 800 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 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.

  • Shipping weight: 33 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 19231308DG.
  • 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.
  • 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 19131308 (single collar, triple-lip contact seals), 19131308G (single collar), 19131308L (single collar, labyrinth seals), 19131308D (triple-lip contact seals), 19131308DL (labyrinth 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.
