Description
Overview:
This Sprocket Bearing is a genuine Husqvarna component for small and mid-range petrol chainsaws, including the Husqvarna 135 and 140. It is a needle roller bearing with a robust steel cage designed to support the clutch drum/drive sprocket, allowing the sprocket to rotate smoothly on the crankshaft. By reducing friction and controlling wear at this critical interface, it helps maintain consistent chain drive and extends the service life of surrounding parts. Identified by OEM No. 503 53 92 01, it is made to Husqvarna's specifications for a precise fit and reliable operation in demanding cutting conditions. Suitable for professional users and DIY maintenance, it restores smooth sprocket function when the original bearing becomes worn or noisy.
Key Features:
- Genuine Husqvarna part for assured compatibility and performance (OEM No. 503 53 92 01)
- Needle roller design for smooth, low-friction rotation of the clutch drum/drive sprocket
- Precision-made to fit correctly and run true, helping to protect the crankshaft and sprocket
- Durable steel construction for long service life under heat and load
- Helps prevent chain speed fluctuation and premature wear of the rim or spur sprocket
- Suitable for routine service when replacing sprockets or clutch components
- Simple, straightforward replacement for worn or damaged bearings
- Supports reliable cutting performance across a wide range of Husqvarna models
Typical Applications:
Restoring smooth operation of the chainsaw drive system by supporting the clutch drum and sprocket. Ideal when the chain drive feels rough, the sprocket wobbles, or during scheduled maintenance alongside sprocket, clutch, or drum replacement. Suited to felling, logging, pruning, firewood cutting, and general property maintenance tasks.
