The SK200 Top Roller is a heavy-duty replacement undercarriage component designed for KOBELCO SK200 excavators. Also known as a carrier roller or upper roller, it supports the upper track chain, maintains proper track alignment, and contributes to stable crawler movement across demanding job sites.
Manufactured from high-strength forged alloy steel and processed with precision machining, induction hardening, and advanced sealing technology, this top roller is built to deliver long service life, exceptional wear resistance, and dependable performance in harsh working environments.
Whether your excavator is operating in mining, quarrying, construction, or earthmoving projects, the SK200 top roller provides a durable and cost-effective replacement solution for maintaining undercarriage efficiency.
Engineered for continuous operation, the SK200 top roller provides reliable performance while reducing wear throughout the undercarriage system.
The reinforced roller shell and shaft assembly are designed to withstand high machine loads and demanding working conditions.
A hardened rolling surface minimizes abrasion from continuous track movement, extending both roller life and overall undercarriage durability.
The roller maintains consistent support for the upper track chain, helping improve crawler stability and reduce unnecessary vibration.
Premium floating metal seals effectively retain lubricant while preventing dust, mud, water, and debris from entering the internal components.
Accurate machining and balanced assembly contribute to smooth rotation, reduced friction, and improved operating efficiency.
Installing a high-quality SK200 carrier roller helps achieve:
The SK200 top roller is suitable for various heavy-duty applications, including:
Its durable construction makes it suitable for environments involving abrasive materials, uneven terrain, and long operating hours.
