Product Overview: The Double Rowing Bearing for Trailer, specifically designed for Ifor Williams trailers, ensures optimal performance and durability. This unitized wheel bearing is the latest model, compatible with most Ifor Williams trailers manufactured after 1996. Engineered for reliability, this bearing is an essential component for maintaining the smooth operation of your trailer.

Features:
Ensure your trailer operates smoothly and reliably with the Double Rowing Bearing for Trailer. Ideal for those seeking quality and compatibility with Ifor Williams trailers.
The inner and outer ring raceways are segments of cones and the rollers are tapered so that the conical surfaces of the raceways, and the roller axes, if projected, would all meet at a common point on the main axis of the bearing. This geometry makes the motion of the cones remain coaxial, with no sliding motion between the raceways and the outside diameter of the rollers.
This conical geometry creates a linear contact patch which permits greater loads to be carried than with spherical (ball) bearings, which have point contact. The geometry means that the tangential speeds of the surfaces of each of the rollers are the same as their raceways along the whole length of the contact patch and no differential scrubbing occurs.
The rollers are stabilized and restrained by a flange on the inner ring, against which their large end slides, which stops the rollers from popping out due to the "pumpkin seed effect" of their conical shape.
The larger the half angles of these cones the larger the axial force that the bearing can sustain.
Tapered roller bearings are separable into a cone assembly and a cup. The non-separable cone assembly consists of the inner ring, the rollers, and a cage that retains and evenly spaces the rollers. The cup is simply the outer ring. Internal clearance is established during mounting by the axial position of the cone relative to the cup, although preloaded installations without clearance are common.
Metric tapered roller bearings follow the designation system defined by ISO 355.
