2 M3000 4-BOLT FLANGE NON-EXPANSION WITH LABYRINTH SEALS

The 2" M3000 4-Bolt Flange Non-Expansion Bearing with Labyrinth Seals is Moline Bearing Company part 19711200L: an Even-Lok™ mounted spherical roller bearing 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. M3000 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 21,700 lbf and the static load rating is 22,500 lbf. Maximum speed is 4,900 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.

Mounting dimensions

  • Bolt hole centers: 4 1⁄16 in
  • Bolt circle diameter: 5 3⁄4 in
  • Bolt size: 1⁄2 in
  • Flange: 5 1⁄4 × 5 1⁄4 in
  • Length through bore: 2 9⁄16 in
  • Shipping weight: 10.5 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 19611200L.
  • 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 19711200 (double-lip contact seals).

Replacement parts

The bearing insert is ABSY 22210-200. Open end cap 18621115 and closed end cap 18620115 fit this housing.

Applications

M3000 units are for drives that need expansion and misalignment capability, or where vibration, slippage or fretting corrosion are present. 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 comparable spherical roller bearing units, including Moline's M2000 line.
