100MM M2000 WIDE SLOT TAKE-UP NON-EXPANSION WITH GARTER SEALS
The 100 mm M2000 Wide Slot Take-up Non-Expansion Bearing with Garter Seals is Moline Bearing Company part 19251100G: a mounted spherical roller bearing in the non-expansion position. It is fitted with a spring loaded garter seal and a single 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, which gives it high load capacity and the most misalignment tolerance of Moline's lines. M2000 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 69,900 lbf and the static load rating is 93,300 lbf. Maximum speed is 700 rpm with the spring loaded garter 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 1,325 in-lbs, and the locking system holds 8,400 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 19151100G.
- 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.
- Single Collar. One locking collar secures the insert to the shaft. Standard for unidirectional rotation and steady loads.
- 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 19251100D (double collar, triple-lip contact seals), 19251100DL (double collar, labyrinth seals), 19251100DG (double collar), 19251100 (triple-lip contact seals), 19251100L (labyrinth seals).
Replacement parts
The bearing insert is SLA20.
Applications
M2000 units are the choice where a high-capacity, self-aligning bearing is needed and shaft expansion or misalignment is expected. Moline Bearing Company lists conveying, screening, air handling, paper and forestry, and food processing among the industries that run them. It is directly interchangeable with other collar-mounted spherical roller bearings in single-piece housings, including Moline's M3000 line.
