The Timken 300 Series deep groove ball bearing is the heavy-duty big brother of the 200 Series. Built on a wider cross-section with higher load ratings, the 300 Series handles the punishing radial loads found in large combine headers, grain cart axles, and heavy tillage equipment. These bearings feature metric bores from 17mm to 60mm with machined bore precision for reliable shaft fits.

Where the 200 Series handles standard agricultural loads, the 300 Series steps in when equipment designers need more capacity in the same bore size. The deeper groove geometry provides superior radial load handling and moderate thrust load capability. Available in open, shielded, sealed, and max capacity (W) configurations with snap ring options.

Lambear Industries carries the 300 Series variants most commonly found in agricultural equipment across West Texas. If you’re replacing a bearing on heavy tillage or harvest equipment and the 200 Series doesn’t have enough capacity, the 300 Series is your answer.
