About This Part
The carrier roller on a Kobelco CKE2500 sits above the crawler frame rail and supports the return run of the track chain between the front idler and the sprocket. On a 250-tonne crane doing repeated pick-and-carry cycles, the top roller takes constant lateral load every time the machine slews with the chain under tension.
50Mn forged steel gives higher tensile strength and impact toughness than plain carbon steel. The dual-cone floating seals are pressure-tested to 2.4 MPa on every unit — a failed seal means oil loss and accelerated bearing wear within days on a working machine. CNC turning and grinding hold the tread and shaft journal to tight tolerance; out-of-round tread puts a bounce in the chain at travel speed.
Construction and Key Features
50Mn forged steel body — higher tensile strength and impact toughness than plain carbon steel. Stays round under repeated load cycles.
CNC turning + CNC grinding — tread and shaft journal held to tight tolerance.
Dual-cone floating seals — 2.4 MPa water pressure + air tightness tested on every unit. Fails either test: reworked or scrapped.
Anti-rust paint — for ocean freight and yard storage. Scrape the mounting face clean before fitting.
Custom orders — brand marking, colour, dimensions available for volume distributors.

Frequently Asked Questions
What is a carrier roller on a Kobelco CKE2500 crawler crane?
The carrier roller — also called top roller or upper roller — sits on top of the crawler frame and supports the upper run of the track chain between the front idler and the sprocket. Without it, the chain sags under its own weight and slaps the frame on every travel cycle.
How do I know when the CKE2500 carrier roller needs replacing?
Three things to check: tread surface gone flat or uneven; oil on the ground from a leaking seal face; roller not turning when you push the track chain through by hand. A seized carrier roller drags the chain instead of rolling under it.
Is this a genuine Kobelco OEM part or aftermarket?
Aftermarket replacement only. Kobelco model names are used solely to identify machine fitment. Supplied by ShunQi Track / PartsCrane / Quanzhou Shunqi Construction Machinery Parts Co., Ltd.
Can you supply a full set of Kobelco CKE2500 undercarriage parts?
Yes. Track rollers, carrier rollers, front idlers, sprockets, track shoes and track chain — all checked against the CKE2500 model before shipment. One shipment for the full set saves on freight.
Can you make a carrier roller by sample or drawing?
Yes. Send the worn roller or a dimensional drawing — outer diameter, overall width, shaft diameter, flange type, material grade and quantity. We come back with feasibility, lead time and price.
