30332-A

When you're dealing with heavy truck axles or massive industrial gearboxes, the 30332-A tapered roller bearing is usually the go-to choice for handling punishing radial and one-way axial loads. It's an absolute beast on the shop floor. Weighing in at 29.6 kg with a hefty 160x340x75 mm footprint, the complete 30332-A makes life a lot easier for technicians since the inner cone and outer cup mount entirely separately. That one design tweak alone slashes downtime during messy rebuilds. But what really sets the 30332-A apart from cheaper alternatives is the modified line contact along its raceways. Instead of letting edge stress build up and eventually destroy the unit, this specific geometry basically eats the inevitable shaft deflections you see out on rough haul roads. Throw in a rugged stamped steel cage that holds its own up to 200°C, and it makes total sense why independent parts distributors keep the 30332-A stocked deep on their shelves for high-vibration replacements.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
