2-3/16 M3000 WIDE SLOT TAKE-UP NON-EXPANSION

The 2 3⁄16" M3000 Wide Slot Take-up Non-Expansion Bearing is Moline Bearing Company part 19751203: an Even-Lok™ mounted spherical roller bearing in the non-expansion position. It is fitted with a standard double lip contact 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 30,100 lbf and the static load rating is 30,800 lbf. Maximum speed is 3,100 rpm with the standard double 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. The grease fitting is 1/8-27 NPT.

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 19651203.
• Standard Double Lip Contact Seal. Two lips in series, so the second continues to seal if the first is compromised. A step up in dirty conditions.
• 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 19751203L (labyrinth seals).

Replacement parts

The bearing insert is ABSY 22211-203, and the housing on its own is Moline Bearing Company part 11521203. Open end cap 18621203 and closed end cap 18620203 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.
