Description
Overview:
This genuine Stihl ball bearing (part no. 4243 640 5100) is a precision-made component for the angle drive gearboxes used on selected Stihl hedge trimmer attachments and long‐reach hedge cutters. Made from high‐grade steel with precision‐ground races, it supports smooth, low‐friction rotation of the drive shaft and maintains correct gear alignment under load. A sound bearing is essential to keep the angle gearbox running quietly and efficiently, helping to protect gears and seals from excess wear. Designed specifically for Stihl angle drive systems such as the HL‐KM 0‐145 and FH‐KM 145, it provides a reliable like‐for‐like replacement when the original bearing becomes noisy, rough, or shows play. Suitable for professional and domestic users who need dependable performance from their Stihl equipment.
Key Features:
- Genuine Stihl OEM part for assured compatibility and fit within the angle drive housing
- Precision manufacturing for smooth rotation, stable shaft support, and consistent gear meshing
- Durable steel construction to withstand the radial loads and speeds typical of angle gearboxes
- Helps reduce vibration and noise when replacing worn or pitted bearings
- Supports efficient power transfer from the drive to the cutting head
- Suitable for routine servicing or full gearbox overhauls
- Straightforward replacement for the original bearing when installed using appropriate tools; refer to the service manual
- Designed for the working conditions of hedge trimming, including frequent start/stop use and variable loads
Typical Applications:
Replacement of the angle drive bearing during maintenance of Stihl HL‐KM and HLA series gearheads, especially where there is roughness, play, or noise. Used during gearbox rebuilds after impact, contamination, or long service hours in landscaping, grounds maintenance, and domestic hedge care.
