2053169 Steel Track Roller for W2200 / W250FI Milling Machines

46 kg heavy-duty bottom roller for crawler undercarriage rebuild and replacement

Part Overview

The 2053169 track roller is the bottom roller that carries the machine weight and guides the track chain along the undercarriage of W2200 and W250FI cold milling machines. It is supplied as a complete, ready-to-fit aftermarket replacement: roller body, shaft, end flanges and mounting faces are finished to the original dimensions, so the unit goes onto the existing roller bracket without shaft modification or shim packs.

Specifications

What the Roller Does in Service

A 2-metre class milling machine puts most of its weight through the bottom rollers. Each roller takes vertical load, keeps the chain aligned on the track frame and lets the crawler roll with low friction while the drum is cutting. When a roller seizes or its running surface wears concave, chain pitch starts to climb, the track runs tight on one side and the whole undercarriage works harder.

Because milling work mixes abrasion, vibration and constant steering correction, the roller is a wear item with a predictable service window. Replacing it before the running surface breaks through keeps the chain, idler and sprocket out of the failure chain and protects the track frame from misalignment damage.

Replacement Indicators

• Visible flat spots or a concave groove on the roller running surface
• Roller no longer turns freely by hand, or turns with a grinding feel
• Grease weeping from the seal area, or a dry joint that will not hold grease
• Chain sitting low between rollers, with slack that will not adjust out
• Uneven wear between left and right track frames, or the machine pulling to one side
• Noise and vibration from the undercarriage rising with travel speed

Fitting Notes

1. Lift and block the machine, then release track tension before removing the roller retaining bolts.
2. Clean the roller bracket faces and check the bolt holes for elongation or cracking.
3. Fit the new roller with new high-strength bolts where the old ones show corrosion or thread damage.
4. Grease the unit at the fitting stage, torque to the machine specification, then re-tension the track.
5. Replace rollers in pairs on the same side when wear is even; a single seized roller usually means its neighbours are close to the limit.
6. Run the machine and re-check track tension after the first hours of operation.

Build and Inspection

The roller body is forged from steel and the running surface is hardened to resist abrasion from milled asphalt and concrete grit. Shaft ends are machined to the original diameter, the end faces are checked for squareness, and every unit is turned by hand and greased before packing so a stiff or noisy roller does not leave the warehouse. Units are supplied as aftermarket replacement parts with dimensional interchangeability to the original part number.

Packing and Ordering

Each roller is packed in an individual carton with foam and timber protection, then crated or palletised for sea and air freight; 46 kg per piece means a pair or a full undercarriage set can be consolidated on one pallet. Minimum order is 1 piece, stock items ship in 5-7 working days. Send your machine model, the quantity per side and your destination port and we will confirm the shipping weight and freight option before dispatch.

FAQ

Is this a new part or reconditioned? New aftermarket replacement, greased and hand-turned before packing.

Does it fit both W2200 and W250FI? Yes, both models use the same roller position and mounting dimensions.

How many rollers does one machine need? It depends on the undercarriage layout of your machine; tell us the model and we will list the quantity per side.

Can rollers be ordered together with track pads and idlers? Yes, mixed undercarriage orders can ship on one pallet.
