Product Introduction

The TRA181504 is a large-diameter tapered roller bearing crafted for the most rigorous industrial power transmission challenges. Sized at 90 x 150 x 38.5 mm, this heavy-duty bearing efficiently transmits massive radial and thrust forces in severe environments such as mining equipment and steel rolling mills. Forged in our high-capacity production facility from premium vacuum-degassed bearing steel, the TRA181504 features precision-crowned rollers that eliminate destructive edge stresses under heavy loads. Fully compliant with international quality standards, it stands as a highly reliable solution for B2B heavy machinery procurement.

Applications

Heavy mining crushers and rotary drives.
Steel mill rolling machinery and heavy gear reducers.
Marine propulsion systems and large winches.
