TAPERED ROLLER BEARING
Tapered Roller Bearing
Heavy-duty load capacity, engineered for automotive wheels and heavy-load transmission.
Tapered roller bearings support radial and single-direction axial loads through line contact between rollers and races. When installed in pairs, they offer high combined load capacity, making them ideal for heavy-duty applications and automotive wheel hubs.
Inner Diameter Range
25–60 mm
Accuracy Class
P0 / P6
Structural Form
Single / Pairs
Technical Features
Line-contact load bearing
Roller and raceway profile matching to improve stress distribution under heavy loads.
Pairwise Clearance Control
Control axial clearance according to assembly requirements to minimize on-site adjustment.
Surface strengthening
Optional surface treatments for improved durability in poorly lubricated conditions.
