Essential Undercarriage Components for Reliable Excavation Performance
Growshine International supports customized development of various spare parts, including specialized rotary supports, ring gear bearings, and other precision-engineered components. If you require unique specifications beyond the standard 240-8361 or 2408361, contact us for a tailored manufacturing solution.
The rotary support, often called a slewing ring or swing bearing, is a critical component in any excavator like the CAT 307 or CAT 308. Its primary function is to allow the upper structure of the machine (the cab, engine, and boom) to rotate freely and smoothly relative to the undercarriage. This precision bearing incorporates both a ring gear and bearing elements, facilitating the smooth transfer of axial, radial, and moment loads. The part 240-8361, also known as 2408361, ensures the structural integrity and operational precision of your mini excavator.
Growshine International is your trusted supplier for the CAT Caterpillar 307 and CAT 308 rotary support. The official part number is 240-8361, which is also commonly referred to as 2408361. This rotary support is a direct, high-quality replacement, ensuring reliable machine operation and minimizing downtime. As experts in Engineering Machinery Parts, we understand the need for durable components for heavy equipment. We offer guaranteed quality for your CAT 307 308 swing bearing replacement and other undercarriage needs. We also supply components for Final drive assembly for construction equipment, focusing on precision-engineered components for longevity.
At Growshine International, our core business is the import and export trade of high-demand spare parts, including Engineering Machinery Parts, Heavy Truck Parts, Agricultural Machinery Parts, and Auto Parts. Our goal is to provide a comprehensive supply chain solution, whether you are looking for a small excavator ring gear bearing price or large fleet maintenance components.
For instance, consider the Pinion Gear. This part is located in the Final Drive/Transmission and drives the ring gear. Example: Komatsu PC200-8 Final Drive Pinion Gear. We also stock the Oil Cooler. Located in the Engine or Hydraulic System, it regulates oil temperature. Example: Volvo FH16 Engine Oil Cooler. We are dedicated to the international trade in precision engineered components, ensuring you get the right component for your machinery.
Ensuring your Caterpillar mini excavator undercarriage parts are in top condition prevents costly repairs. The ring gear bearing is essential for smooth swing movement. We also provide high-quality sealing solutions. PROMOTION: Growshine International supplies AP1709, AP1709L bulldozer hydraulic pump skeleton oil seals. Click here to purchase!
Need to stabilize your steering? We offer parts like the Tie Rod End. This connects the rack/arm to the wheel spindle in the Steering System. Example: Ford F-150 Steering Tie Rod End. Another vital piece is the Crankshaft. Located in the Engine Block, it converts reciprocating motion to rotary motion. Example: John Deere 6155R Engine Crankshaft.
Furthermore, we supply advanced hydraulic controls. PROMOTION: Essential imported solenoid valves KDRDE5K-20/30C02-106, SKX5P-17-201 are available now. Click to see details!
As a global export of agricultural machinery components and heavy equipment parts, Growshine is highly versed in machinery components. The Track Roller is a key item. Location: Undercarriage. It supports the weight of the machine and guides the track chain. Example: Hitachi ZX130 Track Roller. We also stock parts for power generation, such as the Turbocharger Compressor Wheel. Located in the Turbocharger, it compresses intake air. Example: Garrett GT40 Turbocharger Compressor Wheel.

We also carry parts from other top brands: Click here to see our list of turbocharger brands: Garrett, Holset, BorgWarner, 3K, Schwitzer, IHI, Mitsubishi, Hitachi, CZ, Toyota, Komatsu, Bosch Mahle.
Fault Scenario: A Caterpillar 345D excavator experiences slow and weak swing movement, even after replacing the rotary support 240-8361.
Diagnosis & Solution: This issue often points to insufficient hydraulic pressure or flow to the swing motor. In many cases, the problem is not the main swing bearing (rotary support) but a malfunctioning swing motor relief valve or a failed Hydraulic Cylinder Rod Seal. Location: Hydraulic Cylinder. It prevents fluid leakage past the piston rod. Example: Caterpillar 345D Hydraulic Cylinder Rod Seal. Check the hydraulic pressure settings for the swing circuit and inspect the relief valves for sticking or breakage. This ensures your CAT 308 swing circle bearing maintenance investment is protected by a fully functional hydraulic system.
Growshine International is committed to Sourcing original quality auto spare parts, including critical engine components. We offer solutions for Engine overhaul kits for off-road vehicles.
Fuel system maintenance is key. Consider the Injection Pump. Location: Fuel System. It pressurizes and delivers fuel to the injectors. Example: Isuzu 4JB1 Injection Pump. We have essential engine gaskets available: PROMOTION: Get 4JB1 engine injector tapered gaskets 8941258591 and 8971713310. Click here to buy on 1688!
Our inventory extends far beyond the CAT 307 rotary support 240-8361. We are major suppliers for Agricultural Machinery Parts. The Tractor PTO Shaft is a common item. Location: Transmission/Rear Axle. It provides rotational power to implements. Example: Kubota L4701 Tractor PTO Shaft. For heavy truck maintenance, we stock components like the Air Spring. Location: Suspension System. It provides load support and damping. Example: Freightliner Cascadia Air Spring. We are your source for Cost-effective heavy truck brake linings and Reliable auto suspension system exporter solutions.
