KOYO Single-row tapered roller bearings, Able to carry radial and axial load in one direction simultaneously. Combined radial and axial load can be also accommodated. Suitable for heavy load and impact load. The larger the contact angle (α) is, the greater the bearing resistance to axial load.
Koyo tapered roller bearings whose bearing numbers are suffixed by “J” are precision ground in accordance with the ISO 355 (Sub-unit, Metric Series) specifying
the outer ring width and small inside diameter as well as the contact angle, so that outer rings and inner ring assembly (inner ring, rollers and cage assembly) of
these bearings are internationally interchangeable.
Various part numbers in stock, welcome inquiry. Fast shipment within 2-3 working days.
