Products Description
CG260/1E34F Brush Cutter Needle Bearing
CG260 / 1E34F Brush Cutter Needle Bearing – Precision Engine Component
This needle bearing is a direct replacement for the crankshaft assembly in the 1E34F engine platform, which powers CG260, BC260, TL26, and similar 25.4cc brushcutters.
The bearing reduces friction between the crankshaft and connecting rod, enabling smooth rotation and efficient power transfer. In a two-stroke engine, the crankshaft needle bearing is subject to high loads and RPM, making it a wear-prone component that can fail over time. This replacement bearing restores the engine's smooth operation and prevents more serious damage to the crankshaft or connecting rod. It is designed to meet original equipment specifications for the 1E34F engine platform.
Technical Profiles & Materials
Precision Engine Fitment – This needle bearing is manufactured to meet original equipment specifications for the 1E34F engine platform, which powers CG260, CG260A, CG260B, BC260, TL26, Zenoah BC260, and other brushcutters. The bearing is installed between the crankshaft and connecting rod at the lower end of the connecting rod.
High-Load Capacity – The needle bearing is designed to handle the high loads and RPM of a two-stroke engine. It reduces friction between the crankshaft and connecting rod, ensuring smooth rotation and efficient power transfer from the piston to the crankshaft.
Durable Steel Construction – Manufactured from high-quality bearing steel with precision-ground needle rollers, designed to withstand the high temperatures, vibration, and stress common in brushcutter engines. The durable construction ensures long service life under demanding conditions.
BC411 Compatibility Reference – A crankshaft needle bearing is confirmed as a compatible spare part for BC411 brushcutters and is cross-compatible with models including BC260, BC330, BG328/CG328, CG411, BC430/BC520, CG139, and GX25/GX35. This confirms the same bearing family is used across the CG260/1E34F platform and other popular brushcutter engines.

Products Application
Engine Overhaul & Rebuild
Direct replacement when rebuilding the 1E34F engine on CG260 and compatible brushcutters. The needle bearing is a critical component that should be inspected and replaced if worn or damaged. Symptoms of a failing bearing include knocking sounds from the engine, excessive vibration, or loss of power.
Friction Reduction & Power Transfer
The needle bearing reduces friction between the crankshaft and connecting rod, enabling smooth rotation and efficient power transfer from the piston to the crankshaft. A worn bearing increases friction, leading to reduced performance and potential engine damage.
Professional Workshop & Fleet Maintenance
For repair centers and landscaping contractors maintaining CG260, BC260, and TL26 brushcutters, having replacement needle bearings in stock facilitates quick engine rebuilds. The bearing is essential for restoring engine performance and extending the service life of the equipment.

FAQ
Q: How do I confirm this needle bearing fits my brushcutter?
A:Check your machine model number and engine type. This needle bearing is designed for the 1E34F engine platform, which powers CG260, CG260A, CG260B, BC260, TL26, and Zenoah BC260 models. A compatible needle bearing is also confirmed for BC411 brushcutters and cross-compatible with BC260, BC330, BG328/CG328, CG411, and other models.
Q: What are the symptoms of a worn needle bearing?
A: Common symptoms include knocking sounds from the engine, excessive vibration, loss of power, or difficulty starting. A worn bearing can cause the connecting rod to move irregularly on the crankshaft, leading to engine damage if not replaced promptly.
Q: When should the needle bearing be replaced?
A: The needle bearing should be inspected during any engine overhaul or if symptoms of wear appear. It is a critical component that should be replaced if it shows signs of wear, scoring, or damage. During a full engine rebuild, replacing the needle bearing is standard practice to ensure reliable operation and extend engine life.
