Other characteristics


Duplex bearings are two matched bearings which provide the following bearing characteristics: · accurate bearing positioning in radial and axial directions from a defined clearance to controlled rigidity. · limitation of the yield of the system. · higher load capacity compared to a single bearing. The matching of the bearings is achieved by loading each single bearing with the desired preload and then relieving the inner and/or outer rings until the surfaces of both rings are flush with each other. Two bearings machined in this way are assembled according to their markings and the instruction on the package, and loaded axially with the specified or required force. Depending on the matching used, either the inner rings or the outer rings, or even both rings are clamped together. The ball bearings must be mounted in accordance with the installation instructions on the packaging labels or the marks on the ball bearings. Deep groove radial bearings: Unless specified otherwise by the customer, GRW matches deep groove radial bearings with a preload of 5 N and a nominal contact angle of 15°. On request, preload and contact angle can be adjusted to customer's individual operating requirements. For Duplex bearings, radial clearance should be selected higher than normal to achieve a greater contact angle, rigidity, and axial loading.
