This is the aftermarket replacement bottom (center) roller for several Bobcat® compact track loaders. This older style with threaded posts and nut installation if phasing out so when you order online you will likely receive the newer bolt version if you do not specify that you need the post type roller. This is also commonly known as part number 6689371 and 6686632.
You can also view the bolt style bottom roller listing as well. Evaluate all of your rollers during routine inspections and replace all of the failing rollers at the same time to be more efficient and to maximize the lifespan of the undercarriage.
This roller fits the following models:
- Bobcat® T140
- Bobcat® T180
- Bobcat® T190
- Bobcat® T200
- Bobcat® T250
- Bobcat® T300
- Bobcat® T320
- Bobcat® T630
- Bobcat® T650 (verify that you have a solid mount undercarriage, this does not work for the suspension mount systems)

Shaft Threading 3/4 UNC -- Max Torque NM 425 -- Max Torque 310 FT LB
This part number is the previous generation post and nut part number but we have a newer bolt-style roller that has replaced it as well.
Roller Installation Location
Older Bobcat® T190 models have three bottom track rollers per side, while newer models have four rollers per side so double check your machine prior to ordering. It is always best to replace the rear idler and the bottom roller to the rear of the machine at the same time. When the T190 loader drives without a load in the bucket the weight of the machine is on the rear idler and the bottom rollers that are towards the back of the machine so the wear on the back rollers are at a faster pace than the front rollers.
