2-3/16 ME3000 PILOTED FLANGE NON-EXPANSION WITH LABYRINTH SEALS

The 2 3⁄16" ME3000 Piloted Flange Non-Expansion Bearing with Labyrinth Seals is Moline Bearing Company part 29731203L: an Even-Lok™ mounted spherical roller bearing with Type E dimensions in the non-expansion position. It is fitted with a balanced steel labyrinth seal and a single collar, Even-Lok insert, in a solid Class 30 cast iron housing with a standard painted finish.

It carries a genuine SKF® Explorer spherical roller insert and locks to the shaft with Moline's Even-Lok™ concentric system, which grips nearly 360° of the shaft instead of at set-screw points, reducing fretting and slippage. A Hex-L key for mounting and dismounting ships with it. ME3000 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 30,100 lbf and the static load rating is 30,800 lbf. Maximum speed is 4,500 rpm with the balanced steel 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 290 in-lbs. The grease fitting is 1/8-27 NPT.

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 29631203L.
  • Balanced Steel Labyrinth Seal. A non-contact seal using a maze-like gap rather than a rubbing lip. No friction and no lip wear, so it suits high speed and high temperature.
  • Single Collar. One locking collar secures the insert to the shaft. Standard for unidirectional rotation and steady loads.
  • Even-Lok. Moline's concentric locking system, which clamps the insert evenly around the shaft rather than at set-screw points. Improves concentricity and holding power versus set screws.

The same size is also built as 29731203 (double-lip contact seals).

Replacement parts

The bearing insert is ABSY 22211-203. Open end cap 18621203 and closed end cap 18620203 fit this housing.

Applications

ME3000 units are for Type E-footprint mounts where vibration, slippage or fretting corrosion would loosen a set-screw insert. Moline Bearing Company lists conveying, screening, air handling, industrial laundries and high-speed fans 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 ME2000 lines.
