The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factor e (from the data table): the larger the value of e, the larger the contact angle.

Tapered Roller Bearing Assembly - 25 mm Bore, 52 mm OD, 15 mm Cone Width, 13 mm Cup Width, Class K Precision Rating. Delivery time estimates are based on real-time product availability and standard ground shipping. Product inventory is reserved during Checkout.Tapered roller bearing cones and assemblies with a double row design can have three basic arrangements. The face-to-face (TDI) configuration joins the load lines toward the axis, the back-to-back (TDO) configuration separates the load lines toward the axis, and the tandem configuration sets the load lines parallel to one another.
