3-1/2 SPLIT E1000 CARTRIDGE WITH LABYRINTH SEALS
The 3 1⁄2" Split E1000 Cartridge Bearing with Labyrinth Seals is Moline Bearing Company part 19373308L: a tapered roller bearing cartridge. It is fitted with a balanced metal labyrinth seal and a double collar, set screw locking insert.
It is the replaceable solid cartridge from Moline's Split E1000 units: a genuine Timken® Enhanced DEE tapered roller insert, case-hardened and made from vacuum-degassed steel, in its own cartridge, so a worn bearing is swapped without removing the split housing from the shaft. Split E1000 units are made, machined and assembled in the USA.
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
Maximum speed is 1,640 rpm with the balanced metal labyrinth seal fitted, and the seal is rated for 0° to 350°F.

This configuration
- Balanced Metal Labyrinth Seal. A non-contact metal labyrinth seal — excludes contamination through path geometry rather than contact, so nothing 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 19373308 (standard V-Guard contact seal).
Replacement parts
The bearing insert is NPE42350DEE-401C4.
Applications
It fits Moline's Split E1000 split housings for a 3 1⁄2" shaft. The split housing is for shafts that cannot be dismantled to feed a solid bearing on, in the same high radial and thrust load service as Type E: conveying, screening, cranes, mining, forestry, oil, gas, power generation and aggregate. It is dimensionally interchangeable with comparable Type E units, including Moline's Type E, ME2000 and ME3000 lines.
