110MM ME2000 PILOTED FLANGE NON-EXPANSION DOUBLE COLLAR WITH GARTER SEALS
The 110 mm ME2000 Piloted Flange Non-Expansion Bearing with Double Collar Insert and Garter Seals is Moline Bearing Company part 29231110DG: a mounted spherical roller bearing with Type E dimensions in the non-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 in a solid cast iron housing with an integrated center support, so it gives spherical-roller misalignment and expansion capability in a Type E footprint. ME2000 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 91,700 lbf and the static load rating is 126,000 lbf. The insert accepts up to 1.5° of angular misalignment. Set screws torque to 1,325 in-lbs, and the locking system holds 11,000 lbf of radial load before the insert slips on the shaft. 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 29131110DG.
- 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 29231110 (single collar, triple-lip contact seals), 29231110G (single collar), 29231110L (single collar, labyrinth seals).
Replacement parts
The bearing insert is SLAA22-110.
Applications
ME2000 units are specified where a Type E footprint needs more misalignment or expansion capability. Moline Bearing Company lists conveying, screening, air handling, laundries, food processing, and paper and forestry 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 ME3000 lines.
