The IHI 35N Track Roller is a durable aftermarket undercarriage component designed for the IHI 35N mini excavator. Also known as a bottom roller or lower roller, it supports the track chain and helps distribute machine weight along the lower section of the crawler frame.

Xiamen Doozer manufactures replacement track rollers with a focus on strength, precision, and wear resistance. The roller is produced from high-strength steel and precision-machined to maintain consistent dimensions and reliable contact with the track chain. Controlled heat treatment improves the working surface’s resistance to repeated loads and abrasive wear, helping the roller perform in demanding construction and earthmoving applications.

The bottom roller works together with the track chain, front idler, sprocket, and upper rollers to maintain stable crawler operation. A worn roller can create abnormal track movement, vibration, and uneven wear across the undercarriage. Replacing a damaged or excessively worn roller with a properly matched IHI 35N track roller can help restore smooth track movement and reduce unnecessary stress on other components.

The IHI 35N parts catalog identifies a Lower Roller Assembly as part of the lower machine assembly. Aftermarket suppliers also specifically list bottom/track rollers for the IHI 35N mini excavator. Some catalogs additionally cover related IHI 35N-2, 35NX, and 35UJ variants, but fitment can differ between configurations. Therefore, the machine model, serial number, and original roller should be checked before ordering.
