Description
Overview:
The Needle Cage Bearing 12x17x13 is a genuine Stihl component for heavy‐duty chainsaws such as the MS 880 and MS 780. It supports rotating assemblies by guiding hardened needle rollers within a precision cage, helping to reduce friction, heat and wear under continuous high-speed use. The bearing size is 12 x 17 x 13 mm, which is approximately 0.47 x 0.67 x 0.51 inches, ensuring the correct fit where specified by Stihl. As an OEM part (9512 933 3170), it is made to Stihl tolerances for reliable alignment and smooth operation in demanding environments. Use it to maintain performance and extend service life in key engine or drive locations where a needle roller cage is required.
