E312 Caterpillar Excavator Carrier Roller
The E312 Caterpillar Excavator Carrier Roller is a forged steel component designed to support and guide the track chain on excavators in the 10 to 30-ton class. It is manufactured from 50Mn alloy steel, hardened to 48-52 HRC, and features a smooth, machined surface finish to reduce friction and wear. This roller is a direct replacement for Caterpillar models including EX100, EX200, and EX300 series.
The roller body is forged to ensure grain flow alignment, improving fatigue resistance under cyclic loading. The internal bearing assembly uses sealed ball bearings with grease lubrication, typical for heavy-duty undercarriage components. Surface finish is ground to a tolerance of ±0.02mm to maintain alignment with the track link. The color is standard yellow, achieved through a protective coating applied after heat treatment.
This carrier roller is purchased by repair shops, fleet operators, and mining contractors in Southeast Asia, Africa, and Latin America who maintain used Caterpillar equipment. It is sold individually or in sets of two or four. Lead time is typically 15 to 25 days. The supplier offers a 12-month warranty against material defects. Buyers should confirm the exact machine model and serial number to ensure fitment.

Sourcing E312 Caterpillar Excavator Carrier Roller from Reachong Machinery & Equipment Co., Ltd. - China Import Guide
Before ordering, confirm the exact excavator model and serial number to ensure the E312 roller fits your undercarriage. Compatibility lists provided by the supplier are general; variations exist between production years. Request a dimensional drawing or compare with your worn part before purchase.
Confirm the Incoterms, lead time, and packaging method. The supplier offers FOB Dalian or FOB Qingdao, with lead times of 15 to 25 days. Payment is typically by T/T, with 30% deposit. Ask for a packing list that includes batch numbers and inspection certificates. Shipments are usually by sea in wooden crates.
Inspect the roller upon arrival for surface cracks, bearing play, and coating damage. Rotate the roller by hand to check for smooth movement. If possible, perform a magnetic particle inspection to detect subsurface cracks. Retain the first batch for reference if ordering in multiple shipments.
